Was bedeutet der Fehlercode?
The circuit to the right knock sensor gives a signal that is too low. The cause may be that the cable is short-circuited to ground or broken, so that the circuit is open. The engine control module (ECM) compares the signal with its limits and sets the fault code when it lies outside them.
Mögliche Ursachen
- Signal cable short-circuited to ground
- Contact resistance in the knock sensor connections
- Break in the signal cable
- Short circuit between the knock sensors' signal cables
- Damaged knock sensor
Was Sie tun können
- 1Clear the fault code and test drive the car to see whether it returns
- 2Check that the cable from the right knock sensor is not broken and has no ground contact; with a multimeter, measure against the body
- 3Check the connectors in the wiring to the right sensor for contact resistance and oxidation
- 4If you have a diagnostic tool: read the knock signal from the right sensor in live data with the engine running and see whether the value is missing or too low
- 5Have a workshop with diagnostic equipment check and repair the wiring and replace the knock sensor if needed
Symptome, die Sie bemerken können1
- Poor performance and lack of power while driving
Was der Fehler beeinflussen kann2
- Ignition timing is retarded as a safety measure
- Boost pressure is reduced
