Was bedeutet der Fehlercode?

The engine control module (ECM) monitors the heated oxygen sensor by checking its signal. The code is set when the sensor's heater circuit behaves abnormally. Although the code is named for a high signal, it concerns the heater circuit, and the fault may lie in the connections, the wires or the sensor.

Mögliche Ursachen

Contact resistance
Signal wire shorted to earth
Signal wire shorted to supply voltage
Open circuit in the signal wire
Damaged oxygen sensor

Was Sie tun können

1Check that the fuses are intact
2Inspect the oxygen sensor connections and check them for contact resistance, looseness and oxidation. Rust-dissolving spray and grease should not be used
3Use a multimeter to check that the signal wire is not shorted to earth or supply voltage and has no break
4If the wiring is in order, try a new oxygen sensor
5If the fault remains, have a workshop with diagnostic equipment diagnose further
