P0341 on a 2022 Toyota Camry
Camshaft Position Sensor Range / Performance
What does P0341 mean on a 2022 Toyota Camry?
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.

How to diagnose this on a 2022 Toyota Camry
-
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
Known Technical Service Bulletins for the 2020-2024 Toyota Camry
Manufacturers publish Technical Service Bulletins (TSBs) when a known issue affects a specific vehicle. These bulletins come from the NHTSA database for your Toyota Camry.

NHTSA #11028726 - ELECTRICAL SYSTEM Jan 27, 2026
Some 2018 – 2024 model year Toyota vehicles equipped with a Premium Audio with Dynamic Navigation System require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software.
NHTSA #11028722 - UNKNOWN OR OTHER Jan 6, 2026
Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
NHTSA #11028712 - ENGINE Aug 6, 2025
The specific condition covered by this program is for a small engine coolant leak that can occur from the flow shut-off valve that can allow coolant to drip on other parts of the vehicle. This can cause "Engine Maintenance Required" to be displayed on the instrument cluster or cause the A/C not to function normally. Although the flow shut-off valve is covered by Toyota’s New Vehicle Limited Warranty for 36 months or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to Flow Shut-off Valve Coolant Leak.

About the 2020-2024 Toyota Camry
The 2020-2024 Toyota Camry was commonly sold with the following powertrains: 2.5L I4, 3.5L V6, 2.5L Hybrid I4. Common trims include LE, SE, XLE, XSE.
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.
