What this code means
P0341 may mean the PCM is seeing the camshaft position and crankshaft position relationship as incorrect or out of expected sync.
What the vehicle may do
- The vehicle may run rough.
- The engine may have an extended crank.
- Power may be reduced.
- The warning light may come on with few noticeable symptoms.
Possible fault areas
- Possible VTC control issues.
- Possible camshaft timing concerns.
- Possible cam chain or tensioner concerns.
- Possible crank pattern learning concern.
Diagnostic path
Opening context
On this 2016 to 2024 Honda Civic with the 2.0 gas engine, P0341 is a cam and crank phase code. In plain language, the PCM is seeing the intake camshaft position signal and crankshaft position signal not lining up the way it expects. The vehicle may run rough, may have a longer crank, may lack power, or may just set the light with limited driveability symptoms. Broadly, this can involve possible VTC control issues, cam timing problems, timing chain or tensioner concerns, or the learned crank pattern side of the strategy. Treat it like a mechanical synchronization and VTC diagnostic, not just a sensor code.
Start with the basic checks and related VTC context
Start with the basic system checks and follow a structured diagnostic approach before getting deep into the P0341 path. If another VTC system code is present, handle that first, because it can point you toward the same system that affects the cam phase relationship.
Work through the P0341 inspection path
After that, work the P0341 path in order. The checks are centered around the intake-side VTC oil control, camshaft timing, the VTC actuator, the cam chain, and the cam chain auto-tensioner. Keep the order straight, because this code is about whether the cam and crank relationship is believable under the expected VTC conditions.
Cam chain check
For the cam chain inspection, check the chain for damage or stretch. A normal result is no damage and no stretch. If that inspection is abnormal, the path points to a cam chain problem.
If the listed inspections are normal
If all the inspection items in this troubleshooting path are normal, then do the PCM reset, CKP pattern clear, and CKP pattern learn. That step matters because the PCM is comparing cam phase against crank information, so the learned pattern has to be handled correctly before calling the diagnosis finished.
Confirmation procedure one
Keep verification separate from the component checks. For the first confirmation path, turn the vehicle to OFF, in LOCK mode, and let the engine cool below 104 °F (40 °C). Then start the engine and let it idle with no load. For a CVT, use P or N. For a manual transmission, use neutral. If the failure duplicates during this step, that confirmation path is complete.
Confirmation procedure two
For the second confirmation path, turn the vehicle to ON mode and run the HDS IN-VTC function. If that test result is not OK, the failure is duplicated.
Confirmation procedure three
For the third confirmation path, turn the vehicle OFF in LOCK mode again and let the engine cool below 104 °F (40 °C). Start the engine and let it idle with no load, again using P or N for a CVT, or neutral for a manual. Watch VTC Status on the HDS and let the engine idle until VTC Status turns ON. Once it is ON, monitor OBD STATUS for P0341.
Takeaway and CTA
The key with P0341 is to prove the cam and crank phase relationship under the right VTC operating conditions, then verify the repair and confirm the code stays gone. Don’t jump straight to a sensor call when the path is aimed at VTC control, cam timing, chain condition, tensioner condition, and crank pattern learning.

Final check
P0341 is often best approached as a cam and crank synchronization/VTC logic problem rather than assuming one failed sensor.
