HINT
Accelerator pedal positions are expressed as voltages.
MONITOR DESCRIPTION
- When either of the output voltages of VPA or VPA2 deviates from the standard range, or the difference between the output voltages of the 2
sensor circuits is less than the threshold, the ECM determines that there is a malfunction in the accelerator pedal position sensor. The ECM
then illuminates the MIL and sets a DTC.
- Example:
- When the output voltage of VPA drops below 0.4 V for more than 0.5 seconds when the accelerator pedal is fully depressed, DTC P2122
is set.
- If the malfunction is not repaired successfully, a DTC is set 2 seconds after the engine is next started.
