Hva betyr feilkoden?
The engine control module (ECM) monitors the exhaust gas temperature and sets the code when the reading from the temperature sensor ahead of the catalytic converter is wrong. The car may then run with poorer performance, because a calculated value is used instead of the sensor signal.
Mulige årsaker
- Trouble code ECM-P054600 can cause this code
- Signal wire short-circuited to voltage
- Earth lead short-circuited to voltage
- Damaged temperature sensor at the catalytic converter
- Contact resistance, oxidation or open circuit in the connections
- Trouble code ECM-P054500 can cause this code
Hva du kan gjøre
- 1Check that the fuses are intact
- 2Twist and wiggle the wiring at the sensor and see whether the signal drops out
- 3Use a multimeter to check that the signal wire has no contact with voltage or ground
- 4If you have a diagnostic tool: see in live data whether the sensor value follows the engine warming up
- 5If the fault remains, have a workshop measure the sensor resistance and repair the wiring as needed
Symptomer du kan merke2
- The car runs with poor performance and lacks power
- The engine hesitates, surges or runs unevenly, especially during acceleration
Hva feilen kan påvirke1
- A calculated value is used instead of the sensor signal
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
