P0341 on a 2017 Toyota Camry
Camshaft Position Sensor Range / Performance
P0341 on a 2017 Toyota Camry 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 2017 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.
This guide covers P0341 across the 2015-2019 Toyota Camry generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2015 through 2019.
Is it safe to drive a 2017 Toyota Camry with P0341?
In most cases a 2017 Toyota Camry 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 2017 Toyota Camry?
- 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
- Hesitation under acceleration
- Possible heat-soak failure pattern

| 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 2017 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

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.

The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.
NHTSA #11020657 - STRUCTURE Dec 6, 2024
To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
NHTSA #11012743 - STRUCTURE Dec 6, 2024
The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

About the 2015-2019 Toyota Camry
The 2015-2019 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.
