Throttle Position (TP) Sweep Inspection

Throttle position (TP) sweep inspection

1. Connect the WDS or equivalent to the DLC-2.
2. Turn ignition switch to ON position.
3. 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.) Diagnostic Trouble Code Descriptions

4. Access TP_REL PID.
5. 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

6. Gradually move the throttle valve and verify that the PID reading increases linearly.
- If the PID reading drops momentarily, inspect the following:
- TP sensor

7. 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.
