Code number. P0125: feedback mode setting circuit (the signal of the oxygen sensor)

Possible cause

• Failure of the front oxygen sensor.

• Damage to the wire harness in the oxygen sensor circuit or poor contact in the connector.

• Failure of the rear oxygen sensor.

NOTE: When the degradation of the front oxygen sensor is the nominal voltage care (as a new sensor), equal to about 0.5 V at the stoichiometric composition of the working mixture. The implications of this care the rear oxygen sensor is adjusted. If the rear oxygen sensor reacts badly to changes in the composition of the working mixture degradation as a result of its own, it can not cope with the task of correcting the front of the sensor signals. Thus, even if the regulation system switches to feedback mode, the voltage amplitude at the leading sensor decreases and reaches the value of 0.5 V. For this reason, a fault code may be written R0125.
