Throttle Position (TP) Sweep Inspection

Throttle position (TP) sweep inspection

1. Connect the WDS or equivalent to the DLC-2.
2. Reform the KOER self-test function.
3. Verify that none of the following DTCs are displayed:
- P0122, P0123, P0222, P0223, P2100, P2101, P2102, P2103, P2107, P2108, P2119, P2122, P2123, P2127, P2128, P2135, P2138
- If any one DTC is displayed, perform the DTC inspection.

4. Access the TP_REL PID.
5. Verify that the PID reading is within the CTP value. (See PCM INSPECTION [L3 WITH TC].) Diagnostic Trouble Code Descriptions
- 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 the related wiring harness.
- If the throttle valve does not open, inspect the throttle actuator control motor and the related wiring 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 the WOT value. (See PCM INSPECTION [L3 WITH TC].) Diagnostic Trouble Code Descriptions
- If the PID reading is out of range, perform the following:
- Remove the air duct from throttle valve body with connector connected.
- Verify that the throttle valve opens when throttle pedal is depressed.
- If the throttle valve opens, inspect the throttle position sensor and the related wiring harness.
- If the throttle valve does not open, inspect the throttle actuator control motor and the related wiring harness.
