Throttle position (TP) sweep inspection

Connect the WDS or equivalent to the DLC-2.
Turn the ignition switch to the ON position.
Verify that none of the following DTC are displayed:
- P0122, P0123, P0222, P0223, P0638, P2100^*2 , P2101, P2102^*2 , P2103^*2 , P2106^*1 , P2107, P2108, P2109^*1 , P2112^*1 , P2119, P2122, P2123, P2127, P2128, P2135, P2138
  ^*1 : California emission regulation applicable model
  
  ^*2 : Except for California emission applicable model
  - If any one DTC is displayed, perform DTC inspection.
Access TP_REL PID.
Verify that the PID reading is within the CTP value. (See PCM INSPECTION ).
- If the PID reading is out of range, perform the following:
  - Remove the air duct from the throttle valve body.
  - Verify that the throttle valve opens when the accelerator pedal is depressed.
    - If the throttle valve opens, inspect the throttle position sensor and related wiring harness.
    - If the throttle valve does not open, inspect the throttle actuator control motor and related wiring harness.
Gradually depress the throttle pedal and verify that the PID reading increases accordingly.
- If the PID reading drops momentarily, inspect the following:
  - Throttle position sensor
Fully depress the throttle pedal and verify that the PID reading is within WOT value. (See PCM INSPECTION ).
- If the PID reading is out of range, perform the followings:
  - Remove the air duct from throttle valve body.
  - Verify that the throttle valve opens when throttle pedal is depressed.
    - If the throttle valve opens, inspect the throttle position sensor and related wiring harness.
    - If the throttle valve does not open, inspect the throttle actuator control motor and related wiring harness.
