Co oznacza ten kod błędu?
The engine control module finds that the control of the heater element in the front oxygen sensor on bank 1, sensor 1, has not worked for a certain period. The code belongs to electrical faults where the resistance is wrong.
Możliwe przyczyny
- Oxidised connectors with raised contact resistance
- The front oxygen sensor is damaged
Co możesz zrobić
- 1Make sure the fuses are intact. Their location is on the fuse chart or in the instruction manual
- 2Read the fault code with a diagnostic tool with the engine running and see whether it is active
- 3Check the connector on the front oxygen sensor for bank 1 sensor 1 for oxidation and contact resistance
- 4With a multimeter, check that the wiring to the sensor has no open circuit and no short to ground or supply
- 5Replace the front oxygen sensor if the fault remains after checking the connector and wiring
- 6Have a workshop with diagnostic equipment check the control of the heater element if the fault comes back
Objawy, które możesz zauważyć1
- The Check engine lamp lights up or behaves abnormally
