Co oznacza ten kod błędu?
The code concerns the signal from the oxygen sensor, which the engine control module (ECM) uses to assess the fuel and air mixture. It is set when the signal is too low, and the last measured value is then used.
Możliwe przyczyny
- Signal wire shorted to ground
Co możesz zrobić
- 1Read the code with a diagnostic tool and check whether it is active or only stored
- 2Check that the signal wire to the oxygen sensor is not shorted to ground, for example from chafing or moisture
- 3Use a multimeter to check that the signal wire from the sensor has no contact with ground (the body) when the connector is unplugged
- 4With a diagnostic tool you can read the oxygen sensor signal in live data when the engine is warm and see whether it responds to the throttle
- 5Have a workshop calibrate the oxygen sensor, and check the sensor if the fault remains
Objawy, które możesz zauważyć1
- No noticeable symptoms for the driver
Na co może wpływać usterka1
- The last value measured by the oxygen sensor is used
