Throttle Position (TP) Sweep Inspection

Connect the WDS or equivalent to the DLC-2.
Turn ignition switch to ON position.
Verify that following DTCs are not displayed:
- P0121, P0122, P0123, P0221, P0222, P0223, P2100, P2101, P2102, P2103, P2107, P2108, P2119, P2122, P2123, P2127, P2128, P2135, P2136
  - If any DTC is displayed, perform DTC inspection. (See DTC TABLE .)
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 air duct from throttle body.
  - Verify that throttle valve moves when the accelerator pedal is depressed.
    - If the throttle valve moves, inspect the following:
  - TP sensor and related harness
    - If the throttle valve does not move, inspect the following:
  - Throttle actuator control motor and related harness
Gradually move the throttle valve and verify that the PID reading increases linearly.
- If the PID reading drops momentarily, inspect the following:
  - TP sensor
Fully depress the accelerator pedal and verify that the PID reading is within the WOT value. (See PCM INSPECTION .)
- If the PID reading is out of range, perform the following:
  - Remove air duct from throttle valve body.
  - Verify that the throttle valve moves when the accelerator pedal is depressed.
    - If the throttle valve moves, inspect the TP sensor and related harness.
    - If the throttle valve does not move, inspect the throttle actuator control motor and related harness.
