Throttle Position (TP) Sweep Inspection

Connect the M-MDS to the DLC-2.
Switch the ignition to ON.
Verify that none of the following DTCs are displayed:
- P0122:00, P0123:00, P0222:00, P0223:00, P0638:00, P2100:00, P2101:00, P2107:00, P2108:00, P2119:00, P2122:00, P2123:00, P2127:00, P2128:00, P2135:00, P2138:00
  - If any one DTC is displayed, perform the DTC inspection. (See DTC TABLE [MZR 2.5] .)
Access the TP REL PID.
Verify that the PID reading is within the TP REL 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 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:
  - TP sensor (See THROTTLE POSITION (TP) SENSOR INSPECTION .)
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. (See THROTTLE POSITION (TP) SENSOR INSPECTION .)
    - If the throttle valve does not open, inspect the throttle valve actuator control motor and related wiring harness.
