ACCELERATOR POSITION SENSOR ADJUSTMENT [MZR-CD (RF Turbo)]

BME014041609W02

  Caution

  • Adjusting the accelerator position sensor unnecessarily may adversely affect engine control. Therefore, adjust accelerator position sensor only when it is replaced.

  Note

  • Accelerator position sensor adjustment is based on the output voltage with the accelerator pedal fully released. Therefore, be sure to adjust according to the following procedure. (Begin adjustment with the accelerator pedal fully released.)

1. Visually inspect all accelerator pedal components for looseness.

2. Install the accelerator position sensor.

3. Verify the power circuit voltage.

  (1) Verify that the voltage between the PCM terminals 90 (power circuit) and 91 (GND circuit) is 4.75-5.25 V.

  Note

  • Voltage at the PCM terminal 10 may deviate when the power circuit voltage is abnormal.

4. Adjust the output voltage when the accelerator pedal is fully released.

  (1) Verify that the voltage between the PCM terminals 10 (accelerator position detection signal) and 91 is as shown below according to the accelerator pedal conditions.

  • If not as specified, move the accelerator position sensor to adjust the installation position of the accelerator position sensor so that the PCM terminal 10 voltage is within the specification.

Specification

Accelerator pedal condition | Output voltage (V)
--- | ---
Fully released | 0.5-0.7 (Target value: 0.6)
Gradually depressed | Increases linearly

5. Verify that the output voltage when the accelerator pedal is fully depressed.

  (1) Depress the accelerator pedal fully and verify that the voltage at the PCM terminal 10 is within the specification.
Specification

  3.4-3.8V (Target value: 3.6 V)

6. After completion of Steps 1. through 5, inspect the idle switch.
