What this code means
P0341 may indicate that the PCM is seeing the camshaft position and crankshaft position relationship out of the expected phase relationship.
What the vehicle may do
- The engine may idle rough.
- The engine may be harder to start.
- The vehicle may feel low on power.
- The malfunction indicator may come on with few obvious drivability symptoms.
Possible fault areas
- Possible intake-side VTC control concern.
- Possible camshaft timing concern.
- Possible cam chain or tensioner concern.
- Possible cam-to-crank phase relationship concern.
Diagnostic path
Opening context
On this 2016 to 2024 Honda Civic with the 1.5 turbo engine, P0341 is a cam and crank phase code. In plain terms, the PCM is seeing the intake camshaft position signal and the crankshaft position signal not line up the way it expects. The car may have a rough idle, harder starting, reduced performance, or it may just set the light with little obvious complaint. The broad areas here are the intake-side VTC control, cam timing, the cam chain and tensioner, and the general cam-to-crank phase relationship. The key is not to guess at a sensor right away; work through the timing and VTC path in order.
Check related VTC faults first
Before going into the P0341 test path, start with the basic system checks and follow a structured diagnostic approach. If another intake-side VTC fault is present, handle that first. A problem in that system can affect the same cam phase control this code is judging, so clearing that context before chasing P0341 keeps the diagnosis from going sideways.
Work through the inspection items
Next, work through the P0341 inspection path. Check the VTC oil control solenoid valve A, inspect camshaft timing, inspect VTC actuator A, then move into the cam chain and cam chain auto-tensioner checks. Think of this as a mechanical and oil-control phase problem until the checks prove otherwise. If all of those inspection items come back normal, then do the PCM reset, CKP pattern clear, and CKP pattern learn.
First confirmation path
To duplicate the fault under the first confirmation path, turn the vehicle to OFF, LOCK mode, and allow the engine to cool below 104 °F (40 °C). Then start the engine and let it idle with no load: CVT in P or N, or manual transmission in neutral. If the failure duplicates here, that confirmation path is complete.
Second confirmation path with the scan tool
For the next confirmation path, turn the vehicle to ON mode, then select HDS IN-VTC. If the test result is not OK, the failure has been duplicated. At that point, stay on the diagnostic path instead of clearing the code and hoping it does not come back.
Third confirmation path and monitor check
For the third confirmation path, again turn the vehicle to OFF, LOCK mode, and let the engine cool below 104 °F (40 °C). Start the engine and let it idle with no load: CVT in P or N, or manual transmission in neutral. Watch HDS VTC Status and confirm it is ON. If it is not ON yet, keep the engine idling until VTC Status turns ON. Then monitor HDS OBD STATUS for P0341.
Cam chain inspection detail
For the cam chain inspection, check the chain for damage or stretch. Normal condition is that there is no damages or stretches. If that inspection is abnormal, there is a problem with the cam chain.
Takeaway and close
The takeaway on P0341 is simple: prove the VTC and cam timing side before blaming a signal. Check related intake-side VTC faults first, follow the inspection order, duplicate the monitor conditions, and verify that P0341 stays gone after the work is complete.

Final check
P0341 often needs a disciplined cam timing and VTC diagnosis before making any parts decision.
