Monitor Description

When either voltage output VPA or VPA2 deviates from the standard ranges, or difference between the voltage outputs of the two sensors is less than threshold, the ECM concludes that there is a defect in the accelerator pedal position sensor. The ECM turns on the MIL and a DTC is set.

Example:

When the voltage output of the VPA is below 0.2 V or exceeds 4.7 V.
