Engine Control
P06A4 Sensor Reference Voltage - General Information

General Description

The ECM provides a 5volt reference voltage to the Air-con Pressure Transducer(APT) and Boost Pressure Sensor(PUT). The ECM monitors reference voltage deviation from the power supply circuit of the APT and DTP.

DTC Description

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

DTC Detecting Condition





( ** APT : Air-Con Pressure Transducer, DTP : Differential Tank Pressure )
