Accelerator Pedal Position Sensor: Inspection

INSPECT ACCELERATOR PEDAL POSITION SENSOR
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch to the ON position.
3. Check if the voltage (ACCEL POS) of the CURRENT DATA indicates the standard value.
  Accelerator pedal released: 0.5 to 1.1 V
  
  Accelerator pedal depressed: 2.6 to 4.5 V
4. Check if the voltage (ACCEL POS #2) of the CURRENT DATA indicates the standard value.
  Accelerator pedal released: 1.2 to 2.0 V
  
  Accelerator pedal depressed: 3.4 to 5.3 V
If not using a hand-held tester, measure the voltage between terminals (VPA - EPA, VPA2 - EPA2) of the ECM connector (see TERMINALS OF ECM ).
REMOVE ACCELERATOR PEDAL ROD
1. Disconnect the accelerator pedal connector.
