P2614 – Camshaft Position Signal Output Circuit/Open

System: Powertrain | Standard: ISO/SAE Controlled | Fault type: Circuit/Open

Definition source: SAE J2012/J2012DA (industry standard)

DTC P2614 indicates the powertrain control module detected a problem in the camshaft position signal output circuit that is consistent with an open circuit condition. In practical terms, the module is not seeing the expected camshaft position signal being output or carried through the circuit path it monitors, often due to a break in continuity, an unplugged connection, or poor terminal contact. The exact monitored circuit path, connector locations, and diagnostic logic can vary by vehicle, so confirm component locations, pinouts, and test procedures using the correct service information before testing or repairs. Treat this code as an electrical circuit integrity fault until testing proves otherwise.

What Does P2614 Mean?

P2614 means Camshaft Position Signal Output Circuit/Open. Based strictly on the official definition, the fault is in the circuit responsible for the camshaft position signal output, and the failure mode is an open (loss of continuity) rather than a signal that is simply too high, too low, or implausible. SAE J2012 defines how DTCs are structured and categorized; for this code, the key takeaway is that the module has identified an electrical circuit integrity problem affecting the camshaft position signal output path it supervises. The DTC alone does not prove a specific component is bad; it indicates the circuit is not electrically intact as expected.

Quick Reference

  • Subsystem: Camshaft position signal output circuit (camshaft position sensing/signal distribution path).
  • Common triggers: Unplugged connector, broken conductor, poor terminal fit, backed-out pin, corrosion causing an open, or an internal open in a related component.
  • Likely root-cause buckets: Wiring/connector integrity, camshaft position sensor or related signal source, power/ground to the signal source (varies by vehicle), module-side terminal issues, harness damage.
  • Severity: Often moderate to high; may cause hard starting, stalling, reduced performance, or a no-start depending on how the vehicle uses the cam signal.
  • First checks: Verify connectors fully seated and locked, inspect harness routing for damage, check for loose/backed-out terminals, confirm recent repairs didn’t leave something unplugged.
  • Common mistakes: Replacing the sensor immediately without continuity testing, overlooking connector pin fit, ignoring harness flex points, or chasing “timing” issues when the fault type is Circuit/Open.

Theory of Operation

The camshaft position signal is used by the control module to determine camshaft position and/or rotational phase relative to the crankshaft. Depending on vehicle design, the signal can be produced by a camshaft position sensor and then carried through a harness to the module, or it may be processed and distributed through additional circuitry. The “signal output circuit” wording indicates the monitored path is focused on the signal being delivered/available at an expected point in the circuit.

For a Circuit/Open fault, the module typically detects that the signal is missing or not transitioning as expected due to a loss of electrical continuity. Common ways this occurs include an open in the signal wire, an unplugged connector, poor terminal contact, or an internal open in the signal source. Because this is an open-circuit category DTC, diagnostics should prioritize continuity, connector integrity, and terminal tension over interpreting waveform “quality” or correlation concerns.

Symptoms

  • Check engine light: MIL illuminated and P2614 stored as current or history.
  • No-start: Engine may crank but not start if the cam signal is required for synchronization (varies by vehicle).
  • Hard start: Extended crank time, especially after hot soak or intermittent connection changes.
  • Stalling: Engine may stall at idle or during decel if the signal drops out due to an open in the harness.
  • Reduced power: Limited performance or protective operating mode when the module cannot rely on cam position input.
  • Rough running: Misfire-like behavior or unstable idle if the signal intermittently opens and reconnects.
  • Intermittent symptom pattern: Condition may appear/disappear with vibration, engine movement, or harness movement.

Common Causes

  • Open circuit in the camshaft position signal output wire between the sensor and the control module (broken conductor inside insulation, chafed-through section)
  • Connector not fully seated at the camshaft position sensor or at the control module, creating an open signal path
  • Terminal/pin issues causing an open: spread terminals, poor pin fit, backed-out pins, or damaged locking tabs
  • Corrosion or contamination at connector terminals leading to an effective open circuit under load or vibration
  • Damaged harness routing near heat sources or moving components causing intermittent opens that become hard opens
  • Camshaft position sensor internal open circuit (sensor electronics or internal solder joint failure)
  • Open in the sensor’s power feed or sensor ground return (the sensor cannot drive a valid output if it is not powered or grounded)
  • Control module input circuit open or poor internal connection (less common; confirm all external wiring first)

Diagnosis Steps

Tools typically needed include a scan tool capable of reading/recording live data and freeze-frame, a digital multimeter, and back-probing or breakout leads appropriate for the connectors. A wiring diagram and connector pinout for your exact vehicle are essential. If available, use a lab scope for signal integrity checks, but keep all measurements within service information procedures.

  1. Confirm DTC P2614 is active. Record freeze-frame data and any companion DTCs, especially those related to cam/crank signals, sensor power supply, or module voltage. Clear codes and see if P2614 resets immediately or only after a drive cycle.
  2. Perform a visual inspection of the camshaft position sensor area and harness routing. Look for unplugged connectors, damaged conduit, harness tension, chafing points, prior repair splices, or contact with hot or moving components.
  3. Inspect both the sensor connector and the module-side connector(s) involved (varies by vehicle). Check for bent pins, pushed-out terminals, spread terminal tension, corrosion, moisture, or damaged seals. Correct any obvious connector retention issues before deeper testing.
  4. With the ignition off, gently tug-test each wire at the connector rear (do not pull hard). A wire that stretches or pulls out indicates a broken conductor or poor terminal crimp that can create a circuit/open condition.
  5. Check the sensor power and ground circuits first, because a powerless sensor may appear as a missing output. Using the wiring diagram, verify the sensor’s feed and ground presence per service information. If either circuit is open, diagnose that open before condemning the signal output circuit.
  6. Test the signal output circuit for continuity end-to-end (sensor connector pin to module connector pin) using a multimeter with the circuit isolated as required by service procedures. An open reading indicates a break, backed-out pin, or terminal issue. If continuity is marginal, move the harness during the test to identify an intermittent open.
  7. Perform a wiggle test while monitoring either the continuity measurement (when safely isolated) or the scan tool PID that reflects camshaft position signal availability (naming varies by vehicle). Wiggle the harness at known stress points, at connectors, and along the engine-to-body transition. Any dropouts indicate an intermittent open that must be located and repaired.
  8. Check for short-to-ground or short-to-power on the signal wire only after addressing opens. A damaged harness can present multiple faults; however, stay focused on conditions that can result in a missing/open output. Correct any abnormal findings per wiring diagram.
  9. Perform voltage-drop testing across suspect connections in the sensor feed and ground circuits while the circuit is operating (where applicable). Excessive drop indicates high resistance that can mimic an open under certain conditions. Compare results to service information and repair poor connections.
  10. If wiring, connectors, and sensor power/ground test good, evaluate the sensor itself. If service information provides a functional test or substitution procedure, follow it. If a known-good sensor restores the signal and P2614 does not return, the original sensor is likely faulty.
  11. Only after confirming the entire external circuit path is intact, consider a control module input/circuit issue. Re-verify pin fit at the module, connector seating, and any inline connectors. If all external checks pass and the fault persists, follow manufacturer-approved module diagnostics.

Professional tip: When chasing a circuit/open code, prioritize pin fit and connector retention. A connector can look clean but still be electrically open due to a backed-out terminal or weak terminal tension. Use the correct terminal test probes and perform a controlled harness movement test while logging live data so you can correlate signal loss to a specific harness segment or connector.

Possible Fixes & Repair Costs

Repair costs for P2614 vary widely because the same “circuit/open” fault can come from simple connection issues or deeper harness or module problems. Total cost depends on the confirmed failure point, parts availability, labor time for access, and post-repair verification steps.

  • Repair or replace damaged wiring in the camshaft position signal output circuit after confirming an open with continuity testing
  • Clean, re-pin, or replace loose/corroded connectors and terminals (restore proper terminal tension and contact)
  • Correct routing and secure the harness to prevent stretch, abrasion, or heat damage that can reopen the circuit
  • Repair related power supply or ground distribution issues that indirectly cause the circuit to appear open (as verified by voltage-drop testing)
  • Replace the camshaft position sensor only if testing confirms the sensor or its internal circuitry is open (varies by vehicle design)
  • Repair or replace the control module connector, if pin fit or terminal damage at the module is verified as the open point
  • Perform required relearn/initialization procedures and clear codes after repairs, then confirm the monitor runs and passes

Can I Still Drive With P2614?

P2614 indicates an open in the camshaft position signal output circuit, which can lead to unstable operation depending on how the control system uses that signal. If you notice stalling, a no-start condition, severe misfiring, reduced power, or any warning that affects braking/steering, do not drive—have the vehicle towed and diagnosed. If the engine runs smoothly and the code is stored without symptoms, short, cautious driving to a repair facility may be possible, but verify with service information and avoid high-load conditions.

What Happens If You Ignore P2614?

Ignoring P2614 can allow an intermittent open to become a permanent open, increasing the chance of a sudden stall or no-start and leaving you stranded. Continued operation with an unreliable camshaft position signal can also cause drivability issues, poor performance, and recurring warning lights, and it can complicate diagnosis as additional codes may set due to unstable engine control inputs.

Key Takeaways

  • P2614 is specifically a camshaft position signal output circuit/open condition, not a “high,” “low,” or plausibility fault.
  • The most common confirmed causes are connector/pin issues and wiring opens; test the circuit before replacing parts.
  • Use a wiggle test and continuity checks to locate intermittents, and verify power/ground integrity with voltage-drop testing.
  • Severity varies by vehicle; it may be a mild warning or can cause stalling/no-start if the signal is critical.
  • Repairs should be based on the verified open point and validated by a completed monitor run after clearing codes.

Vehicles Commonly Affected by P2614

  • Passenger cars with electronically managed gasoline engines using camshaft position sensing
  • Light-duty trucks and SUVs with variable valve timing systems (design varies by vehicle)
  • Vehicles with engine harnesses routed near high-heat areas where insulation and terminals can degrade
  • High-mileage vehicles where connector pin tension, corrosion, or terminal fretting is more likely
  • Vehicles recently serviced near the camshaft sensor or engine harness where connectors may be left partially seated
  • Vehicles operated in environments that promote corrosion at connectors (humidity, road salt exposure)
  • Vehicles with tight engine bay packaging where harness chafing against brackets or covers is more common
  • Vehicles that experience frequent vibration or rough-road use that can aggravate intermittent opens

FAQ

Does P2614 mean the camshaft position sensor is bad?

No. P2614 only tells you the control module detected an open in the camshaft position signal output circuit. A failed sensor is possible on some designs, but wiring, terminals, and connector issues are often more likely and must be tested first.

What is the difference between “circuit/open” and “circuit high/low”?

“Circuit/open” points to a broken path or poor connection (unplugged connector, broken conductor, poor pin fit). “Circuit high” and “circuit low” indicate the signal is being driven too high or too low electrically (often shorts or reference/ground issues). The diagnostic approach and likely causes differ.

Can an intermittent connection set P2614?

Yes. A loose terminal, partially seated connector, or chafed wire can open only under vibration or engine movement. This is why a wiggle test and live-data logging during the same operating conditions that set the code are important for confirmation.

Will clearing the code fix P2614?

Clearing the code only resets stored fault information; it does not repair the open circuit. If the underlying open remains, P2614 will typically return once the monitor runs again or the circuit fault occurs during operation.

What should be checked first for P2614?

Start with the easiest, highest-yield checks: confirm connectors are fully seated, inspect for terminal damage or corrosion, look for harness damage near heat/moving parts, and perform continuity testing of the signal output circuit from end to end. Verify findings with service information for the specific vehicle.

After any repair, confirm the fix by clearing codes, running the applicable monitor, and verifying the camshaft position signal output circuit remains stable during a wiggle test and a road test under similar conditions to when P2614 originally set.
