Co oznacza ten kod błędu?

Although the code is named for a high signal from the front oxygen sensor in bank 1, it is set when the sensor responds too slowly as the mixture changes. The ECM checks the sensor's wear by measuring how quickly it responds. The test only runs while driving, and the code is only stored once the ECM has started the test and the conditions for it have been met.

Możliwe przyczyny

Short circuit between the sensor's current-carrying wires
Open circuit in the sensor signal wire
Open circuit in the wire that supplies the sensor's calibration current
Damaged front oxygen sensor

Co możesz zrobić

1Read the code, clear it and road test the car to see whether it comes back
2Clean soot and dirt from the connector and make sure it is fully engaged; do not use rust solvent spray or grease
3Use a multimeter to check the wires to the oxygen sensor for open circuits and for shorts to each other
4If you have a diagnostic tool: compare the oxygen sensor value in live data with the engine warm; it should change as the mixture switches between rich and lean
5If the fault remains after these checks, replace the front oxygen sensor
