P0341: Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or Single Sensor)
Updated November 14, 2026
The camshaft position sensor tells the engine computer where the camshaft is so it can time fuel and spark. P0341 means the signal is there but doesn't look right: it's erratic, has missing or extra pulses, or doesn't line up with the crankshaft signal the way the computer expects.

🔧 Want to check this yourself? An OBD2 scanner reads the code; models with live data also show the sensor readings used in the checks below. See code readers and scanners from $24.99 ↓ · Which scanner do I need?
Common causes
- A failing camshaft position sensor
- A loose or corroded connector, or wiring that's chafed or picking up interference
- A damaged camshaft tone wheel or reluctor
- A stretched timing chain or a timing belt that has jumped a tooth
- A problem with the crankshaft position sensor signal it's being compared against
Code meanings can vary slightly by manufacturer. Use these as a starting point and confirm with your vehicle's service information or a mechanic before replacing parts.
Symptoms
- Hard starting or long cranking
- Stalling or rough running
- Check engine light, sometimes with no other symptoms
Is it safe to drive?
If the engine stalls, runs rough, rattles or won't start, don't drive it; have it towed, since a slipped timing belt or chain can cause major engine damage. If it runs normally with a steady light, drive gently and get it checked soon, because it can stall without warning.
How to check it with a scanner
- Plug an OBD2 scanner into the port under the dashboard and read all stored codes and the freeze-frame data (the conditions when the code set).
- Scan for related codes, especially crankshaft sensor and cam/crank correlation codes, which point toward timing problems.
- With the engine off, inspect the sensor connector and wiring, especially where the harness runs near spark plug wires, coils or the alternator.
- Remove the sensor and check its tip for damage, oil sludge or metal debris.
- Listen for timing chain rattle at cold start, keeping hands and tools clear of the belts and fan. If you suspect timing, leave the inspection to a shop.
- After a repair, clear the code and drive normally for a few days to confirm it doesn't come back.
A basic code reader shows the code; scanners with live data let you watch sensor readings, which is what you need for most of the checks above. See OBD2 scanners under $100.

Read the code and freeze-frame data with an OBD2 scanner, then: Scan for related codes, especially crankshaft sensor and cam/crank correlation codes, which point toward timing problems.
