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..
