Mazda 3 Service Manual: Accelerator Pedal Position (App) Sensor Inspection [Mzr 2.0, Mzr 2.5]
Voltage Inspection
NOTE:
-
Because the APP sensor is integrated in the accelerator pedal, replacing the APP sensor includes replacement of the accelerator pedal.
1. Connect the M-MDS to the DLC–2.
2. Switch the ignition to ON.
3. Verify that the APP sensor output voltage (PID: APP1, APP2) increases according to the increase in 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 accelerator pedal..
4. Verify that the APP sensor output voltage (PID: APP1, APP2) is within the specification when the accelerator pedal is depressed and not depressed..
-
If not as specified, replace the accelerator pedal..
