Heater oxygen concentration sensor



The low level of the input circuit of the heater front oxygen concentration sensor (P0031)
The PCM controls the heater control signal forward gauge of concentration of oxygen in the heating unit 4A output PCM. If the PCM deactivates the heater front oxygen concentration sensor heater, the heater circuit and the oxygen concentration sensor front heated has a low voltage, the PCM block decides that heater circuit is faulty.

The high level of the input circuit of the heater front oxygen concentration sensor (P0032)
The PCM controls the heater control signal forward gauge of concentration of oxygen in the heating unit 4A output PCM. If the block PCM front sensor includes a heater heated the oxygen concentration, and the front sensor circuit heater heated oxygen concentration is high voltage, the PCM block decides that heater circuit is faulty.

The low level of the input circuit of the heater rear oxygen concentration sensor (P0037)
The PCM controls the heater control signal to the rear oxygen concentration sensor heated at terminal block 4D PCM. If the PCM turns off the heater rear oxygen concentration sensor heater, the heater circuit and rear oxygen concentration sensor heating has a low voltage, then the PCM determines that the heater circuit is faulty.

The high level of the input circuit of the heater rear oxygen concentration sensor (P0038)
The PCM controls the heater control signal to the rear oxygen concentration sensor heated at terminal block 4D PCM. If the PCM turns the heater rear oxygen concentration sensor heater, the heater circuit and rear oxygen concentration sensor heating has a high voltage, then the PCM determines that the heater circuit is faulty.
