General Information

Component Location





General Description

The PCM provides a 5volt reference voltage to the Acceleration Position Sensor 2 (APS2), Throttle Position Sensor 1 (TPS1), A/C pressure sensor and power steering sensor. The PCM monitors reference voltage deviation from the power supply circuit of the sensors.

DTC Description

Checking the voltage from sensor power supply every 1.87 sec. under detecting condition, if the value within detecting condition lasts for more than 0.2 sec., PCM sets P0641. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
