Throttle Position (TP) Sweep Inspection

Throttle position (TP) sweep inspection

1. Connect the WDS or equivalent to DLC-2.
2. Turn the ignition switch to ON position.
3. Verify that none of the following DTC are displayed:
- P0122, P0123, P0222, P0223, P0638, P2100*2, P2101, P2102*2, P2103*2, P2107, P2108, P2109*1, P2112*1, P2119, P2122, P2123, P2127, P2128, P2135, P2138
- If any one DTC is displayed, perform DTC inspection.

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 the air duct from throttle valve body.
- Verify that the throttle valve opens when accelerator pedal is depressed.
- If the throttle valve opens, inspect the throttle position sensor and related harness.
- If the throttle valve does not open, inspect the throttle actuator control motor and related harness.

6. Gradually depress the throttle pedal and verify that the PID reading increases lineally.
- If the PID reading drops momentarily, inspect the following:
- Throttle position sensor

7. 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 harness.
- If the throttle valve does not open, inspect the throttle actuator control motor and related harness.
