Accelerator Position Sensor Adjustment - Mazda Mazda6 Workshop Manual Supplement

ACCELERATOR POSITION SENSOR ADJUSTMENT

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.

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.
