On-Vehicle Inspection

ON-VEHICLE INSPECTION

1. CHECK THROTTLE BODY

a. Listen to the throttle control motor operating sounds.
1. Turn the ignition switch ON.
2. When pressing the accelerator pedal position sensor lever, listen to the running motor, Make sure no friction noise comes from the motor.

If friction noise exists, replace the throttle body.

b. Inspect the throttle position sensor.
1. Connect the intelligent tester or OBD II scan tool to the DLC3.
2. Turn the ignition switch ON.
3. Check that the MIL is off.
4. Under CURRENT DATA, the throttle valve opening percentage (THROTTLE POS) should be within the standard value range below.

Standard throttle valve opening percentage: 60% or more

If the percentage is less than 60%, replace the throttle position sensor.

NOTE: When checking the standard throttle valve opening percentage, the transmission should be in the neutral position.
