Engine Control - P06A4 Sensor Reference Voltage 'D' Circuit Low - General Information

General Description

The PCM provides a 5volt reference voltage to the Air-con Pressure Transducer (APT) and Power Steering Pressure Sensor (PSPS). The PCM monitors reference voltage deviation from the power supply circuit of the APT and PSPS.

DTC Description

PCM sets DTC P06A4 if the PCM detects reference voltage of APT and PSPS are lower than threshold value.

DTC Detecting Condition





(** APT : Air-Con Pressure Transducer, PSPS : Power Steering Pressure Sensor)
