P2367 – Cylinder 16 Knock Sensor Circuit

System: Powertrain | Standard: ISO/SAE Controlled | Fault type: Circuit | Location: Cylinder 16

Definition source: SAE J2012/J2012DA (industry standard)

DTC P2367 indicates the control module has detected an electrical circuit fault associated with the knock sensor input for cylinder 16. While knock sensors are used to monitor engine vibration patterns so the module can manage spark timing and protect the engine, this code is specifically about the circuit (wiring, connectors, sensor, and module input path), not a confirmed mechanical knock condition. Code setting criteria and available data (freeze-frame, pending vs confirmed, and monitor behavior) can vary by vehicle, so confirm the exact diagnostics and connector/pin details using the correct service information.

What Does P2367 Mean?

P2367 – Cylinder 16 Knock Sensor Circuit means the powertrain control system detected a fault in the electrical circuit associated with the knock sensor signal for cylinder 16. Under the SAE J2012 DTC structure, the code identifies the subsystem and a specific fault entry; however, the definition here is focused on a circuit problem rather than a performance correlation or a confirmed engine noise event. In practice, this points you toward verifying the sensor’s wiring/connector integrity, power/ground or shielding (as designed), and the control module’s ability to read that circuit reliably.

Quick Reference

  • System: Powertrain
  • Official meaning: Cylinder 16 Knock Sensor Circuit
  • Standard: ISO/SAE controlled
  • Fault type: Circuit
  • Severity: MIL illumination is possible, and the module may limit spark advance or alter engine control strategy, which can reduce performance and efficiency.

Symptoms

  • MIL/Check engine light: Lamp on or pending/confirmed DTC stored.
  • Reduced power: Noticeable lack of acceleration if the module defaults to a more conservative timing strategy.
  • Poor fuel economy: Increased consumption due to protective ignition/tuning changes.
  • Roughness: Light stumble or uneven feel under load if timing is being actively limited.
  • Knock control inactive: Scan tool data may show abnormal or fixed knock sensor activity for the affected cylinder input (varies by vehicle).
  • Intermittent behavior: Symptoms may come and go with vibration, temperature, or harness movement if there is a connection fault.

Common Causes

  • Connector issue at the knock sensor: Unseated connector, corrosion, moisture intrusion, poor terminal tension, or damaged locking tab causing an unstable circuit.
  • Harness damage: Chafed, pinched, melted, or cut wiring between the knock sensor and the engine control module, especially where the loom contacts brackets or hot surfaces.
  • Open circuit: Broken conductor inside the insulation, partially backed-out terminal, or internal break that shows up only with engine movement/vibration.
  • Short to ground or short to power: Wire insulation damage allowing the signal circuit to contact ground, a feed circuit, or another sensor circuit.
  • Poor ground path: Shared ground splice corrosion, loose ground fastener (varies by vehicle), or excessive resistance in the return path affecting sensor signal integrity.
  • Sensor failure: Internal knock sensor fault (electrical) for the cylinder 16 sensor/circuit as defined by the platform’s architecture.
  • ECM/PCM connector or pin-fit concern: Bent pins, fretting, contamination, or intermittent contact at the control module connector related to the knock sensor input circuit.
  • Incorrect part or installation issue: Wrong sensor type for the application, mismatched connector, or improper mounting/torque (varies by vehicle) leading to abnormal circuit behavior and repeat faults.

Diagnosis Steps

Useful tools include a scan tool capable of reading freeze-frame data and live data, a multimeter with back-probing leads, and vehicle-specific wiring diagrams/service information. A breakout lead set, load/proving light (where appropriate), and basic hand tools help with connector checks. If available, an oscilloscope can aid signal inspection, but avoid relying on generic “normal” values—use service specs.

  1. Confirm the DTC and capture data: Scan for P2367 and record freeze-frame, pending codes, and any related powertrain DTCs. Note engine speed/load and conditions when the fault set.
  2. Check for related electrical issues first: If multiple sensor circuit codes or module voltage codes are present, diagnose power/ground integrity to the control module before focusing on the knock sensor circuit.
  3. Locate the correct circuit for “Cylinder 16 knock sensor”: Use service information to identify which physical knock sensor and which ECM/PCM pins correspond to the cylinder 16 knock sensor circuit (architecture varies by vehicle).
  4. Perform a visual inspection: Inspect the knock sensor connector, wiring loom routing, and nearby heat sources. Look for rub-through, oil saturation, melted insulation, missing clips, and corrosion at terminals.
  5. Connector and terminal checks: With ignition off, disconnect the sensor and inspect for bent pins, pushed-out terminals, poor pin fit, or contamination. Repair terminal tension issues and verify the connector locks positively when reinstalled.
  6. Wiggle test for intermittents: Reconnect components, clear codes, and run the engine while gently flexing the harness at key points (near the sensor, along the loom, and at the module connector). Watch live data and DTC status for dropouts; repeat under similar conditions to the freeze-frame snapshot.
  7. Circuit continuity and open detection: With ignition off and connectors unplugged as required by service info, test continuity end-to-end on the knock sensor signal circuit. If continuity is unstable when flexing the harness, isolate the section with the internal break.
  8. Short-to-ground and short-to-power tests: Check the signal circuit for unintended continuity to ground and to power/other circuits (key off). If a short is found, trace the harness for contact points and repair insulation or routing.
  9. Voltage-drop testing under load: Where applicable and safe per service procedures, apply an appropriate circuit load and measure voltage drop across suspect connectors, splices, and grounds. Excessive drop indicates high resistance even if continuity seems acceptable.
  10. Verify sensor operation electrically per service info: If wiring and connections test good, follow the manufacturer procedure to evaluate the knock sensor electrically (resistance/signal check method varies). Replace the sensor only if it fails the prescribed test.
  11. Module-side verification: If the sensor and wiring are verified good, inspect the ECM/PCM connector for fretting, moisture, or pin damage, and verify pin fit. Consider module input integrity only after all external circuit faults are eliminated.
  12. Clear codes and validate the repair: Clear DTCs, perform the specified drive cycle or enable criteria, and re-scan for pending/confirmed faults. Confirm the condition does not return and that no new circuit codes appear.

Professional tip: Treat P2367 as a circuit problem until proven otherwise. A clean continuity check alone can miss high-resistance terminals and vibration-related opens, so combine visual inspection, a harness wiggle test, and voltage-drop testing. When the fault is intermittent, focus on recreating the freeze-frame conditions and logging live data while manipulating the harness and connectors to pinpoint the exact failure location.

Need wiring diagrams and factory-style repair steps?

Powertrain faults often require exact wiring diagrams, connector pinouts, and guided test steps. A repair manual can help you confirm the cause before replacing parts.

Possible Fixes & Repair Costs

Repair costs for P2367 vary widely because the underlying issue can range from a simple connection problem to component or control-module faults, and labor depends on sensor access and harness routing. Confirm the circuit failure with testing before replacing parts.

  • Repair wiring damage: Restore continuity by repairing chafed, pinched, broken, or heat-damaged sections of the knock sensor circuit harness for cylinder 16.
  • Clean and secure connectors: Remove corrosion, correct moisture intrusion, and ensure terminals are fully seated with proper pin fit at the sensor and control module connectors.
  • Correct power/ground issues: Repair shared grounds, reference feeds, or shielding/drain paths (varies by vehicle) that affect the knock sensor circuit’s electrical integrity.
  • Replace the knock sensor (if proven faulty): Replace only after verifying the circuit is intact and the sensor fails the specified tests in service information.
  • Address connector/terminal tension: Replace loose terminals, damaged locks, or spread pins that create intermittent opens or high resistance in the circuit.
  • Update or replace the control module (rare): Consider only after confirming all external circuit, connector, and sensor checks pass and service information supports module-level diagnostics.

Can I Still Drive With P2367?

You may be able to drive short distances if the vehicle runs normally, but treat P2367 as a powertrain electrical fault that can affect knock detection and engine control strategies. If you experience reduced power, severe drivability issues, abnormal noises, stalling, a no-start, or any warning that affects braking or steering, do not drive—have the vehicle inspected and repaired promptly.

What Happens If You Ignore P2367?

Ignoring P2367 can lead to ongoing MIL illumination and potential drivability changes because the control module may limit performance or alter ignition strategy when knock sensor circuit information is unreliable. Prolonged operation without restoring proper circuit function can increase the chance of poor fuel economy, hesitation, misfire-like behavior, or engine protection modes, depending on vehicle strategy.

Vehicles Commonly Affected by P2367

  • Engines with cylinder-specific knock monitoring: Configurations that assign knock sensing logic to individual cylinders (varies by vehicle).
  • Multi-bank engines: Layouts with longer harness runs and multiple sensor locations that increase exposure to heat and vibration.
  • Vehicles with under-intake sensor placement: Designs where sensor access requires removing components, increasing risk of disturbed connectors after service.
  • High-mileage powertrains: Aging wiring insulation and terminal tension loss can raise the likelihood of circuit faults.
  • Applications with extensive engine harness routing: More clips, brackets, and contact points can lead to chafing or pinched wiring.
  • Vehicles operating in harsh environments: Moisture, road salt, and debris can accelerate connector corrosion and terminal contamination.
  • Recently serviced engine bays: Work near the intake, cylinder heads, or harness junctions can leave connectors partially latched or wires strained.

FAQ

Does P2367 mean the engine is knocking?

No. P2367 indicates a cylinder 16 knock sensor circuit fault. The code points to an electrical circuit issue detected by the control module, and actual knock (a mechanical combustion event) is not confirmed unless additional testing supports it.

Should I replace the knock sensor immediately for P2367?

Not automatically. Start by checking the circuit and connectors for damage, poor pin fit, corrosion, and routing issues. Replace the knock sensor only if it fails the specified tests and the wiring/connector integrity is confirmed.

Can a wiring problem cause P2367 even if the sensor is good?

Yes. Opens, high resistance, short-to-ground, or short-to-power conditions in the harness or terminals can trigger a circuit DTC even when the knock sensor itself is functioning properly.

Will clearing the code fix P2367?

Clearing the code only resets stored fault information. If the underlying circuit problem remains, the code will typically return after the monitor runs again, sometimes immediately and sometimes after a drive cycle, depending on vehicle logic.

Why does diagnosis for P2367 require service information?

Knock sensor circuit design, connector pinouts, shielding/grounding strategy, and test procedures vary by vehicle. Service information provides the correct wiring diagram and the exact test steps needed to confirm the fault and avoid unnecessary parts replacement.

For best results, complete repairs only after verifying the cylinder 16 knock sensor circuit fault with the correct wiring diagram and test procedures for your vehicle, then confirm the fix by clearing the DTC and rechecking after a road test.
