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: (See
ON-BOARD DIAGNOSTIC TEST
article.)
- P0122:00, P0123:00, P0222:00, P0223:00, P2101:00, P2107:00, P2112:00, P2122:00, P2123:00, P2127:00, P2128:00, P2135:00
- If any one DTC is displayed, perform DTC inspection. (See
DTC TABLE
article.)
- Access TP1 TP2 PID. (See
ON-BOARD DIAGNOSTIC TEST
article.)
- Verify that the PID reading is within the CTP value. (See
PCM INSPECTION
article.)
- 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 related wiring harness. (See
THROTTLE POSITION (TP) SENSOR INSPECTION
article.)
- If the throttle valve does not open, inspect the throttle 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
article.)
- 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 wiring harness. (See
THROTTLE POSITION (TP) SENSOR INSPECTION
article.)
- If the throttle valve does not open, inspect the throttle actuator control motor and related wiring harness.
