Co oznacza ten kod błędu?
Although the code is named for a low voltage, it is set when the signal from the front oxygen sensor in bank 1 is outside its permitted operating range, or when the sensor's pre-heating voltage disturbs the signal. The engine control module (ECM) monitors the sensor signal while driving and only sets the code once the test has started and the conditions are met.
Możliwe przyczyny
- Signal wire shorted to the pre-heating circuit
- Ground wire shorted to the pre-heating circuit
- Damaged front oxygen sensor
Co możesz zrobić
- 1Read the code, clear it and road test the car to see whether it comes back
- 2Use a multimeter to check that the wires to the oxygen sensor are not shorted to each other, especially the signal wire against the pre-heating wires
- 3Check that the ground wire to the oxygen sensor is not shorted to the pre-heating circuit
- 4If you have a diagnostic tool: read the oxygen sensor signal in live data with the engine running and check that it is not stuck outside the normal range
- 5If the wiring is intact, replace the front oxygen sensor
Objawy, które możesz zauważyć1
- Check engine light (MIL) on
Na co może wpływać usterka2
- Front oxygen sensor control is switched off
- Catalytic converter diagnostics are disabled
