DTC P0532-00: Refrigerant Pressure Sensor No. 1 Circuit Low Input: Outline

DTC P0532:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Refrigerant pressure sensor No. 1 circuit low input
Detection condition	The PCM monitors input voltage from the refrigerant pressure sensor No. 1. If the input voltage at the PCM terminal 2AV is below 0.168 V for 5 s, the PCM determines that the refrigerant pressure sensor No. 1 circuit has a malfunction.
Fail-safe	Not applicable
Possible cause	Refrigerant pressure sensor No. 1 connector or terminals malfunction Short to ground in any of the following refrigerant pressure sensor No. 1 circuits. Power supply circuit Signal circuit PCM connector or terminals malfunction Short circuit in refrigerant pressure sensor No. 1 signal circuit and ground circuit Open circuit in refrigerant pressure sensor No. 1 power supply circuit Refrigerant pressure sensor No. 1 malfunction PCM malfunction
