P0341 on a 2012 Honda Pilot
Camshaft Position Sensor Range / Performance
P0341 on a 2012 Honda Pilot indicates camshaft position sensor range / performance. It usually stays drivable short-term but should be diagnosed promptly. The most common cause is failing camshaft position sensor (degraded signal) (typically $100–$400). Confirm the root cause before replacing parts.
What does P0341 mean on a 2012 Honda Pilot?
P0341 is set when the ECM does receive a camshaft position signal, but the signal does not behave the way it should — pulses are arriving at unexpected intervals, the cam-crank correlation is drifting, or the signal pattern is irregular. Unlike P0340 (no signal at all), P0341 means the sensor is communicating, but its output is unreliable. The result is rough running, hard starts, and sometimes stalling.
This guide covers P0341 across the 2010-2014 Honda Pilot generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2010 through 2014.
Is it safe to drive a 2012 Honda Pilot with P0341?
In most cases a 2012 Honda Pilot stays drivable for short trips with P0341 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0341 on a 2012 Honda Pilot?
- Check Engine Light is illuminated
- Hard cold start with extended crank time
- Intermittent rough running or misfires
- Stalling at idle or coming to a stop
- Reduced power, especially at higher RPM

| Loose or improperly torqued cam sensor mounting | Occasional | $20–$100 |
| Oil leak at the cam sensor port causing intermittent shorts | Occasional | $80–$350 |
How to diagnose this on a 2012 Honda Pilot
-
Compare cam and crank position signals in live data
Watch cam and crank position PIDs simultaneously while cranking and at idle. Healthy cam-crank correlation maintains a fixed offset. Drift in the offset under load suggests chain stretch; missing or noisy cam pulses point at the sensor or wiring.
Tools: Scan tool with dual-PID graphing
-
Scope the cam sensor signal directly
With an oscilloscope on the cam signal wire, capture the waveform during cranking and at idle. A healthy Hall-effect sensor produces clean square pulses. A variable-reluctance sensor produces clean sine pulses. Noisy, missing, or irregular pulses confirm a sensor or wiring problem.
Tools: Oscilloscope, Back-probe pins
-
Inspect the cam reluctor for damage
Remove the cam sensor and shine a light through the port to see the cam reluctor teeth. Damaged teeth, oil/sludge buildup, or a slipped reluctor wheel will produce P0341. Some engines have hand-pressed reluctors that have been known to slip on the camshaft.
Tools: Inspection mirror, Bright flashlight
-
Check for oil leaking into the cam sensor port
The cam sensor o-ring or gasket can fail and let oil into the sensor body. Oil intrusion shorts the internal electronics intermittently — the sensor reads correctly cold, fails when warm. Replace the sensor with a new o-ring.
Tools: O-ring kit, Clean rags
-
Inspect wiring for chafing
Cam sensor harnesses route near the engine top, exposed to heat and vibration. A chafe point against a metal bracket can create an intermittent short. Visually inspect every inch of the harness, especially where it bends around brackets or near the valve cover.
Tools: Flashlight, Inspection mirror

About the 2010-2014 Honda Pilot
The 2010-2014 Honda Pilot was commonly sold with the following powertrains: 3.5L V6. Common trims include LX, EX, EX-L, Touring, Elite, TrailSport.
P0340 vs P0341
The two cam sensor codes describe different failure modes of the same sensor:
- P0340 — no signal at all. Open circuit, dead sensor, missing power or ground.
- P0341 — signal present but degraded. The sensor is working but its output is unreliable. The diagnostic targets signal quality rather than presence.
P0341 is harder to diagnose because the sensor often passes basic resistance tests. A scope is the right tool — multimeter tests don’t reveal pulse-pattern problems.
When P0341 is actually a timing chain problem
On engines with documented chain wear (BMW N20/N26, Ford 5.4 3V, GM 3.6 LFX/LLT, VW EA888), P0341 can be the first symptom of chain stretch. The cam moves slightly out of phase with the crank as the chain wears — the cam sensor reports its position correctly but it doesn’t agree with where the ECM thinks it should be. Replace the sensor first as the cheap test; if P0341 returns and chain rattle is audible, the chain is the cause.
Oil-soaked cam sensors
If you remove a cam sensor and oil pours out of the port, the sensor body is oil-saturated and the internal electronics are compromised. Replace both the sensor and the o-ring / seal that let oil in. Just cleaning and reinstalling sets P0341 again within weeks.
