DTC P0072-00: Ambient Temperature Sensor Circuit Low Input: Outline

DTC P0072:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Ambient temperature sensor circuit low input
Detection condition	The PCM monitors the input signal from the ambient temperature sensor. If the voltage from the ambient temperature sensor is below 0.2 V, the PCM determines that the ambient temperature sensor circuit has a malfunction.
Fail-safe	Not applicable
Possible cause	Ambient temperature sensor connector or terminals malfunction Ambient temperature sensor malfunction Short to ground in ambient temperature sensor signal circuit PCM connector or terminals malfunction Short circuit in ambient temperature sensor signal circuit and ground circuit PCM malfunction
