    NOTE:
    • Do not remove the accelerator pedal position sensor from the accelerator pedal.
    • Perform the inspection on the hybrid vehicle control ECU side of the connector.
    1. Turn the power switch ON (IG).
    2. Using a voltmeter, measure the voltage between the terminals.

      Standard voltage
