DTC P0073-00: Ambient Temperature Sensor Circuit High Input: Notes

DTC P0073-00:	Ambient temperature sensor circuit high input
DETECTION CONDITION	The PCM monitors the input signal from the ambient temperature sensor. If the voltage from the ambient temperature sensor is above 4.89 V , the PCM determines that the ambient temperature sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (other). The check engine light does not illuminate. FREEZE FRAME DATA is not available. Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	Ambient temperature sensor connector or terminals malfunction PCM connector or terminals malfunction Short to power supply in wiring harness between ambient temperature sensor terminal A and PCM terminal 2Q Open circuit in wiring harness between the following terminals: Ambient temperature sensor terminal A-PCM terminal 2Q Ambient temperature sensor terminal B-PCM terminal 2V Ambient temperature sensor malfunction PCM malfunction
