P0341

Camshaft Position Sensor A Circuit Range/Performance Bank 1 or Single Sensor

Ignition / cam & crank Generic OBD-II High

What it means

P0341 means the camshaft position sensor's signal is present but doesn't line up with what the ECM expects relative to the crankshaft. The engine uses this signal to time fuel and spark, so a mistimed or erratic reading — from a failing sensor, a damaged tone wheel, or even stretched timing — can cause hard starting, stalling, and rough running.

High

Can I keep driving? May run rough, stall, or be hard to start, and can occasionally fail to start; drive cautiously and fix soon.

Common symptoms

What you'll notice

Check-engine light on
Hard starting or intermittent stalling
Rough idle and hesitation
Reduced power or acceleration

Common causes

Most likely first

Faulty camshaft position sensor giving an implausible or mistimed signalLikely
Damaged reluctor/tone wheel or debris on the sensor tipCommon
Damaged or shorted wiring in the sensor circuitCommon
Stretched timing chain or jumped timing causing cam-to-crank correlation to driftLess often
Loose connector, or a failed ECM (rare)Less often

How to diagnose & fix

Work through it in order

Read freeze-frame data and check for crank-sensor or timing-correlation codes (e.g. P0016).
Inspect the cam sensor connector and wiring for damage or corrosion.
Check the sensor tip and reluctor wheel for metal debris or damage.
Compare cam and crank signals; if correlation is off, inspect timing chain/belt and tensioner.
Replace the camshaft position sensor if the signal is out of range. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0341?+

Drive cautiously. The engine can stall or become hard to start, and a timing-related cause could worsen. Get it diagnosed before relying on the vehicle.

Can I just clear P0341?+

It will return once the ECM again sees the cam signal mistimed. Repair the sensor, wiring, or timing issue first, then clear and re-test.
