P0341: Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or Single Sensor)

What does P0341 mean?

The bank 1 camshaft A signal is present but its pattern is not plausible. Electrical interference, a damaged trigger wheel, or a sensor problem can all make cam timing information unreliable.

Generic OBD-II definition: Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or Single Sensor). Confirm applicability in your vehicle service information.

Common causes

• Poor sensor connection or failed cam sensor
• Wiring routed too close to ignition components
• Damaged cam reluctor wheel

Symptoms

• Long cranking or no start
• Reduced fuel economy
• May run normally in fallback mode

Diagnostic focus

A range/performance code does not itself prove the timing chain is stretched. Check correlation codes and waveform evidence rather than replacing timing components on this code alone.

Can I keep driving with P0341?

Severity: High A position-signal fault can cause stalling or failure to restart. Avoid normal use until diagnosed; arrange towing if the engine stalls, runs severely rough, or will not start reliably.

If the check engine light is flashing or the car runs badly, stop driving and have it checked.

Typical fixes

• Inspect bank 1 cam-sensor mounting and connections
• Check harness routing near coils and plug leads
• Compare cam/crank waveforms before deciding on sensor or timing repairs
