Throttle Position (TP) Sweep Inspection
- Connect the M-MDS 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, P2101, P2107, P2108, P2109, P2112, P2119, P2122, P2123, P2127, P2128, P2135, P2138
- If any one DTC is displayed, perform DTC inspection. (See

- Access the 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 body.
- Verify that the throttle valve opens when the accelerator pedal is depressed.
- If the throttle valve opens, inspect the TP sensor and related wiring harness.
- If the throttle valve does not open, inspect the throttle valve 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:
- 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 body.
- Verify that the throttle valve opens when throttle pedal is depressed.
- If the throttle valve opens, inspect the TP sensor and related wiring harness.
- If the throttle valve does not open, inspect the throttle valve actuator control motor and related wiring harness.
