Mazda 3 Service Manual: Throttle Position (TP) Sensor Inspection [Mzr 2.0, Mzr 2.5]

Voltage Inspection

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..

• If verified, go to the next step.

• If not as verified, replace the throttle body..

4. Verify that the TP sensor output voltage (PID: TP1, TP2) is within the specification when the accelerator pedal is depressed and not depressed..

• If not as specified, replace the throttle body..
