P0341

Camshaft Position Sensor A Range/Performance Bank 1

The engine computer is not getting a camshaft sensor signal that looks correct. This can cause hard starting, rough running, stalling, or poor power. The problem may be the sensor, wiring, timing, or a mechanical engine issue.

Quick answer

AI-CITATION READY

What it means

P0341 means the PCM detected a camshaft position sensor A signal on bank 1, or on a single-sensor engine, that does not match expected range or timing. The signal may be intermittent, noisy, missing, or out of sync with crankshaft position. This can be caused by an electrical fault, a failed sensor, or incorrect engine mechanical timing.

Can you drive with it?

With caution. The vehicle may still run, but it can stall, run poorly, or fail to start. Avoid long trips and high-speed driving until the cause is diagnosed.

Most common causes

Faulty camshaft position sensor
Damaged, loose, or corroded wiring or connector at the camshaft sensor
Engine timing issue such as a stretched timing chain or slipped belt

Typical repair cost

DIY usually runs $20–$150. Typical shop repair lands around $150–$700, depending on the root cause.

04 / Causes

1	Faulty camshaft position sensor	high
2	Damaged, loose, or corroded wiring or connector at the camshaft sensor	high
3	Engine timing issue such as a stretched timing chain or slipped belt	medium
4	Low battery voltage, charging system problems, or poor engine grounds	medium
5	Contaminated sensor tip, oil intrusion, or debris affecting the signal	medium
6	Failed reluctor wheel, cam phaser issue, or internal mechanical engine fault	low
7	Faulty PCM or software calibration issue	low

05 / Diagnostic sequence

01Check for additional codes, especially crankshaft sensor, misfire, or timing-related codes.
02Inspect the camshaft sensor connector and wiring for damage, looseness, corrosion, or oil intrusion.
03Verify battery voltage, charging voltage, and engine ground condition.
04Clear the code and confirm whether it returns during idle, acceleration, or after a cold start.
05Use a scan tool to compare cam and crank sensor data for abnormal timing or dropouts.
06Inspect the sensor mounting area and reluctor path for debris, metal shavings, or physical damage.
07If the engine uses a timing belt or chain, check mechanical timing and tensioner condition.
08Test the camshaft sensor and circuit with a multimeter or oscilloscope if available.
09Replace the sensor only after wiring and timing checks confirm the signal problem is not elsewhere.

06 / Repairs

1	Repair damaged wiring, clean connectors, and secure loose terminals	$20–$150
2	Replace the camshaft position sensor if it fails testing or has an erratic signal	$50–$300
3	Correct low voltage, bad grounds, or charging system problems	$20–$250
4	Repair or replace timing belt, timing chain, tensioner, or cam phaser components	$300–$1,500
5	Update PCM software or replace PCM only after all other causes are ruled out	$100–$800

08 / FAQ

Is P0341 serious?

Yes. It can cause stalling, poor drivability, or a no-start condition.

Can a bad camshaft sensor cause a no-start?

Yes. If the PCM cannot read the cam signal correctly, the engine may not start or may start poorly.

Will clearing the code fix it?

No. Clearing the code only removes the warning. The fault will usually return if the problem is still present.

Can low oil cause P0341?

Low oil can affect cam phasers and timing components on some engines, which can trigger this code.
