P0341 Quick Answer
The bank 1 camshaft position sensor signal is present but does not correlate correctly with the crankshaft signal — the cam pulse pattern, count, or phase relationship is outside expected limits.
What Does P0341 Mean?
Camshaft Position Sensor "A" Circuit Range/Performance (Bank 1). The bank 1 camshaft position sensor signal is present but does not correlate correctly with the crankshaft signal — the cam pulse pattern, count, or phase relationship is outside expected limits.
Symptoms
- Long crank or hard-start condition
- Random misfire codes alongside P0341
- Loss of cylinder-deactivation or VVT functionality
- Reduced fuel economy
Common Causes
- Worn or stretched timing chain causing cam-to-crank phase drift
- Damaged reluctor wheel or trigger ring on the camshaft
- Excessive air gap between sensor and reluctor
- Failing CMP sensor producing noisy or weak signal
- Wiring fault inducing dropout under vibration
- Co-occurs with P0016 (cam-crank correlation) on stretched-chain engines
Diagnosis Steps
You’ll need a scan tool capable of reading live powertrain data, a digital multimeter, and access to the wiring diagram for the specific platform.
- Read cam-to-crank correlation live data (where available).
- Inspect timing-chain wear indicator if the platform has one.
- Scope the CMP signal — square wave with clean edges expected, a noisy or missing-tooth pattern indicates reluctor damage.
- Verify air gap and sensor mounting.
- Measure CMP supply, ground, and signal continuity to the PCM.
Possible Fixes
- CMP sensor replacement (most common fix)
- Timing chain replacement when chain stretch is the root cause
- Reluctor wheel replacement
- Wiring repair
Can I Still Drive With P0341?
The vehicle will usually still drive with P0341 stored, but performance, drivability, or emissions will be degraded. The PCM may inhibit emissions monitors and limit closed-loop fueling adjustments. Drive to a workshop, but don’t ignore the code long-term.
How Serious Is This Code?
P0341 is a moderate-priority fault. It will not prevent the engine from running, but unaddressed it can cascade into related faults or damage downstream components such as the catalytic converter. Address within a few drive cycles.

FAQ
Will P0341 clear itself?
Only if the underlying fault was intermittent and self-corrected. Most root causes are persistent and require physical repair.
Can I clear P0341 without fixing it?
You can clear it with a scan tool, but it will return as soon as the fault condition reappears — typically within one or two drive cycles.
Is P0341 related to other codes?
Often, yes. Adjacent codes in the same circuit or system frequently set together — if P0341 is present, scan for related codes and address them as a group.
