P0341
Fix within a few daysThe engine computer is receiving an inconsistent or incorrect signal from the camshaft position sensor 'A' on Bank 1.
Code P0341 means your engine computer isn't getting a consistent signal from the camshaft position sensor. Common causes: Faulty camshaft sensor (60%), wiring issues (25%), crankshaft sensor (10%). Drivability: Limit driving, fix within a few days. Repair cost: $50-$200 DIY, $150-$500 professional.

Common Causes of P0341
Parts most likely causing this code, ranked by probability
The sensor itself has failed internally, sending an erratic or missing signal to the engine control module (ECM).
60% of P0341 cases are fixed by replacing this part
Damaged, corroded, or loose wiring or a faulty connector prevents the sensor signal from reaching the ECM reliably.
25% of P0341 cases are fixed by repairing wiring or connectors
An incorrect signal from the crankshaft position sensor can cause the ECM to misinterpret the camshaft signal, triggering P0341.
10% of P0341 cases are fixed by replacing the crankshaft position sensor
A stretched timing chain, jumped timing belt, or worn timing components cause the camshaft to be out of sync with the crankshaft.
5% of P0341 cases are fixed by addressing timing chain/belt issues
Check These First (Before Buying Parts)
- Visually inspect the camshaft position sensor's wiring harness and connector for any signs of damage, fraying, corrosion, or loose connections.
- Ensure the engine oil level is correct, as low oil can sometimes affect VVT systems that rely on oil pressure, which can indirectly impact cam sensor readings.
How to Diagnose P0341
- 1Visually inspect the camshaft position sensor wiring and connector for damage, corrosion, or looseness.
- 2Check for any related codes, especially for the crankshaft position sensor (P0335, P0336).
- 3Using a multimeter, test the camshaft position sensor's resistance and voltage output according to service manual specifications.
- 4If possible, use an oscilloscope to monitor the camshaft and crankshaft sensor signals for proper waveform and correlation.
- 5If the sensor and wiring check out, inspect the timing chain/belt for proper tension and alignment.
P0341 on Popular Vehicles
Honda Accord
2003-2012P0341 is common. Often caused by a failing camshaft position sensor, sometimes due to oil leaks contaminating the sensor or its connector.
70% fixed by replacing the camshaft position sensor
Nissan Altima
2002-2012Known for camshaft and crankshaft sensor failures. P0341 often indicates a faulty camshaft position sensor, sometimes accompanied by hard starting or stalling.
65% fixed by replacing the camshaft position sensor
Toyota Camry
2002-2011While less frequent than Honda/Nissan, P0341 can occur. Often related to the sensor itself or wiring issues, particularly if the engine has high mileage.

Frequently Asked Questions
What does P0341 mean?
P0341 indicates the engine control module (ECM) detects an inconsistent or incorrect signal from the camshaft position sensor 'A' on Bank 1. This sensor tells the ECM the exact position of the camshaft for proper engine timing.
Can I drive with P0341?
Limit driving, fix within a few days. If your engine is stalling, has significant power loss, or won't start, do not drive it. Driving with an intermittent signal can cause further damage or leave you stranded.
Will P0341 clear itself?
No, P0341 will not clear itself. The engine control module stores this code until the underlying issue is resolved and the code is manually cleared with a scan tool, or after several drive cycles without the fault recurring.
How do I fix P0341 myself?
Start by visually inspecting the camshaft position sensor wiring and connector. If they look good, replace the camshaft position sensor. If the problem persists, you may need to test the crankshaft position sensor or inspect timing components.
How much does it cost to fix P0341?
DIY repair costs range from $50-$200 for the sensor. Professional repair costs range from $150-$500, including parts and labor.
P0341 keeps coming back - why?
If P0341 returns, it's likely the initial diagnosis missed the true cause. Common reasons include faulty wiring that wasn't properly repaired, a secondary issue with the crankshaft position sensor, or a deeper problem with the engine's mechanical timing components.
Will P0341 fail emissions/smog test?
Yes, P0341 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on automatically results in a failure in most states.
What's the difference between P0341 and P0340?
P0340 indicates a general circuit malfunction for the camshaft position sensor 'A' (Bank 1), meaning the ECM isn't seeing any signal. P0341 specifically points to a 'range/performance' issue, meaning the signal is present but inconsistent or outside expected parameters.
P0341 on Honda Accord?
P0341 is a common code on Honda Accords, especially 4-cylinder models. It often points directly to a failing camshaft position sensor, which can be relatively easy to replace.
Questions to Ask Your Mechanic
Did you check the live data for both the camshaft and crankshaft position sensor signals to ensure they are correlating correctly?
Good answer: Yes, I monitored both signals on the oscilloscope. The camshaft signal was erratic compared to the crankshaft, confirming the cam sensor or its circuit is the problem.

Intermediate - requires careful visual inspection, basic electrical testing with a multimeter, and potentially an OBD-II scan tool for live data.
Cost of Waiting
Ignoring P0341 can lead to your engine stalling unexpectedly, leaving you stranded. In severe cases, if the ECM loses critical timing information, it can prevent the engine from starting at all. A $100 sensor replacement now prevents a tow bill and significant inconvenience later.
While You're In There...
The ECM compares signals from both the camshaft and crankshaft sensors. If you're already diagnosing timing sensor issues, checking or replacing the crankshaft sensor can prevent a related future problem, especially if it's easily accessible.
Tools You'll Need
- Basic hand tools (sockets, wrenches)
- Multimeter
- OBD-II scan tool (to clear codes and check live data)
- Service manual (for sensor specifications and location)
P0341 is a common engine code related to a critical but often straightforward sensor. Most repairs involve replacing an accessible sensor, and your engine will run smoothly again.

Your Next Steps
Step 1: Check the wiring and connector to the camshaft position sensor for any visible damage or looseness. Ensure it's securely plugged in.
Step 2: If the wiring looks good, replace the camshaft position sensor. This is the most common fix for P0341.
Step 3: After replacing the sensor, clear the code with an OBD-II scan tool and test drive the vehicle to confirm the repair. If the code returns, you'll need to investigate the crankshaft position sensor or mechanical timing components.
