Accelerator Pedal Position (App) Sensor Inspection: Notes

NOTE:

Connect the M-MDS to the DLC-2.
Turn the ignition switch to ON position.
Select APP1 or APP2 PID (percentage) on the M-MDS.
Verify that the APP1 or APP2 PID (percentage) changes smoothly while accelerator pedal is gradually depressed.
- If as verified, go to next step.
- If not as verified, perform the "Circuit Open/Short Inspection".

Verify that the APP1 or APP2 PID (percentage) is as indicated in the table below according to the condition of the accelerator pedal.
- If not verified, perform the "Circuit Open/Short Inspection".
  - If there is no open or short circuit, replace the APP sensor. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION ).
