P0341 code definition
Camshaft Position Sensor Circuit Range/Performance
What the P0341 code means
P0341 is an OBD-II generic code that says the engine control module (ECM) detected the engine camshaft position sensor circuit is not within specifications. The sensor pulses do not correlate to the pulses of the crankshaft sensor.
What causes the P0341 code?
The camshaft sensor pulses less times than expected in a specified amount of engine revolutions when compared to the crankshaft sensor.
The wiring or connection to the speed sensor is getting shorted or losing connection intermittently.
What are the symptoms of the P0341 code?
- The Check Engine Light will be illuminated and the code is set in ECM memory.
- The engine could stall or not start when failure is present.
- The engine may have a misfire and may buck or jerk while driving for an intermittent connection.
- The engine may not start or have low power if it does start.
How does a mechanic diagnose the P0341 code?
Scans codes and document the freeze frame data in order to verify the problem.
Clears the engine and ETC codes and road test to verify concern comes back.
Visually checks the wiring and connections to the camshaft sensor for loose connections or damaged wiring.
Disconnects and checks the resistance and signal voltage from the camshaft sensor.
Checks for any corrosion in the sensor connections.
Checks the sensor reluctor wheel for breakage or damage on the camshaft or camshaft gear.
Common mistakes when diagnosing the P0341 code
Failure to check and remove the camshaft sensor to look for excessive amounts of metal on the sensor which may cause erratic or no readings from the sensor
Replacing the sensor when the failure cannot be duplicated
How serious is the P0341 code?
A failed camshaft sensor can cause the engine to run erratic, stall, or not start at all.
An intermittent camshaft sensor signal can cause the engine to run rough, jerk, or misfire while driving.
The Check Engine Light on will cause the vehicle to fail emission testing.
What repairs can fix the P0341 code?
Replacing the faulty camshaft sensor
Replacing a broken reluctor ring on the camshaft gear
Repairing corroded connections to the camshaft sensor
Additional comments for consideration regarding the P0341 code
Code P0341 is triggered when the camshaft sensor does not correlate to the position of the crankshaft. The crankshaft sensor should also be checked during the diagnostic checks for any problems that could cause the code to be received.
