THROTTLE POSITION (TP) SENSOR INSPECTION [MZR 2.5]

CAUTION:
- The inspection cannot be performed with this method correctly if there is a malfunction of the APP sensor or throttle valve actuator. Verify that no DTCs related to the APP sensor or throttle valve actuator are stored before the inspection.

NOTE:
- The TP sensor cannot be removed as a single unit. When replacing the TP sensor, replace it together with the throttle body as a single unit.

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Verify that the TP sensor output voltage (PID: TP1, TP2) varies according to the accelerator opening angle when the accelerator opening angle is gradually increased. On-Board Diagnostic Test

- If verified, go to the next step.
- If not as verified, replace the throttle body. Service and Repair

4. Verify that the TP sensor output voltage (PID: TP1, TP2) is within the specification when the accelerator pedal is depressed and not depressed. On-Board Diagnostic Test Component Tests and General Diagnostics

- If not as specified, replace the throttle body. Service and Repair

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
