P0341: Camshaft Position Sensor "A" Circuit Range/Performance (Bank 1 or Single Sensor)
P0341 means the camshaft position sensor "A" signal on bank 1 (or the single camshaft sensor) is present but erratic or out of time with the crankshaft signal.
Standard title per SAE J2012 / ISO 15031-6 · Updated 2026-11-07 · By CarWhere Research
How P0341 sets
The powertrain control module (PCM) compares the camshaft position (CMP) pulses with the crankshaft position signal. If the CMP pulses are irregular, missing intermittently, or not where expected relative to the crankshaft, P0341 sets. Allowed tolerances vary by manufacturer.
Common causes of P0341
Roughly most likely first; the actual cause depends on the vehicle and needs testing to confirm.
- Intermittent camshaft position sensor
- Wiring rubbing on engine components or electrical interference
- Timing chain or belt stretched or misaligned
- Damaged camshaft tone wheel
- Variable valve timing actuator problems
- Low battery voltage during cranking
P0341 symptoms
- Check engine light on
- Extended cranking time
- Rough idle or hesitation
- Intermittent stalling
How P0341 is diagnosed
- Check freeze frame data and companion codes such as P0016 or variable valve timing codes.
- Test battery and cranking voltage.
- Inspect wiring routing and connectors near ignition components.
- Capture CMP and crankshaft waveforms together to check alignment.
- Inspect timing components if signal alignment is off.
Typical fixes for P0341
- Replace the camshaft position sensor
- Repair or reroute wiring
- Replace a stretched timing chain or misaligned belt
- Repair variable valve timing components
- Charge or replace a weak battery
Replace parts only after testing confirms the cause — a code names the circuit or condition that failed a check, not necessarily the faulty part. We don’t publish per-repair prices; for what households actually spend on upkeep, see car repair costs.

P0341 FAQ
What does code P0341 mean?
P0341 means the camshaft position sensor "A" signal on bank 1 (or the single camshaft sensor) is present but erratic or out of time with the crankshaft signal. The standard definition is "Camshaft Position Sensor "A" Circuit Range/Performance (Bank 1 or Single Sensor)."
Can I drive with a P0341 code?
Usually, for short distances. Hard starts, rough running, or stalling are possible, and a timing problem could be the cause, so get it checked soon.
Can a weak battery cause P0341?
On some vehicles, low voltage during cranking can make the camshaft signal look erratic. Testing the battery is a simple first step.
Does P0341 mean the timing belt jumped?
It can, but it is not the only cause. Sensor and wiring faults are more common, though timing should be checked if a cam/crank correlation code is also present.

Manufacturers can add their own sub-definitions and test conditions; confirm with the factory service information for your year, make and model. Before paying for a repair, check NHTSA for open recalls and your warranty booklet: federal law requires an emissions warranty on major emission-control parts such as the catalytic converter and engine computer.
