Was bedeutet der Fehlercode?
The engine control module (ECM) reads the camshaft position sensor for the exhaust camshaft on bank 2, which is the cylinder bank nearest the passenger compartment. The fault is set when the control module detects an incorrect number of segments over two crankshaft revolutions, which equals one camshaft revolution. The signal is therefore outside the expected range.
Mögliche Ursachen
- Occasional faults in the cable harness or connectors
- Camshaft position sensor fitted incorrectly
- Damaged camshaft position sensor
Was Sie tun können
- 1If you have a diagnostic tool, start the engine and rev it a few times until the diagnosis shows complete, then read the fault status for the code
- 2If the fault status shows Fault found, the fault is active; if it shows No fault found, the fault is not active at this moment
- 3Check that the camshaft position sensor is firmly fitted and in the correct position
- 4Check that the connector to the camshaft position sensor is secure and not oxidised
- 5Measure with a multimeter that the wires to the camshaft position sensor have no open circuit and that the signal cable has no contact with ground or supply voltage
- 6After a repair, check that the diagnosis completes and that the fault status shows No fault found
Symptome, die Sie bemerken können1
- The Check engine (malfunction indicator) light comes on or behaves abnormally
Was der Fehler beeinflussen kann1
- The control module uses the signal from the engine speed sensor instead of the camshaft position sensor
