Co oznacza ten kod błędu?

The camshaft sensor signal is a PWM signal, and the engine control module (ECM) checks it while the engine runs. The fault is stored when the signal stays constantly low, which can be caused by a short to ground in the signal wire. The code applies to the intake camshaft sensor on bank 1, or to the single sensor if the engine has only one.

Możliwe przyczyny

Signal wire short circuit to ground
Open circuit in the supply wire
Loose connections

Co możesz zrobić

1If you have a diagnostic tool, start the engine and read the fault status. 'Fault found' means the fault is permanent.
2Check that the fuses are intact.
3Use a multimeter to check that the signal wire to the camshaft sensor does not touch ground or the body.
4Use a multimeter to check that the supply wire to the camshaft sensor is not broken.
5Check that the connector at the camshaft sensor is secure, since loose connections can cause this code.
6If the fault returns, have a workshop check the wiring between the camshaft sensor and the control module.
