Throttle position (TP) sweep inspection
- Connect the M-MDS to the DLC-2.
- Reform the KOER self-test function.
(See KOEO/KOER SELF TEST ).
- 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.
- P0122, P0123, P0222, P0223, P2100, P2101, P2102, P2103, P2107, P2108, P2119, P2122, P2123, P2127, P2128, P2135, P2138
- 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 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.
- If the PID reading is out of range, perform the following:
- 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
- If the PID reading drops momentarily, inspect the following:
- Fully depress the throttle 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 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.
- If the PID reading is out of range, perform the following:
