ACCELERATOR PEDAL POSITION SENSOR
ADJUSTMENT
Caution
(1) Never attempt to tamper the accelerator pedal position
sensor. The sensor position is precisely adjusted at
factory.
(2) Should it be tampered, follow the procedure below:
1. Connect the MUT-II to the diagnosis connector.
When not using the MUT-II, proceed as follows:
(1) Disconnect the accelerator pedal position sensor
connector. Connect the special tool (test harness:
MB991658) between the disconnected connectors,
and then connect the digital voltmeter to the terminal
No.3 [output terminal of accelerator pedal position
sensor (1st channel)] and to the terminal No.1 [earth
terminal of accelerator pedal position sensor (1st
channel)].
2. Loosen the accelerator pedal position sensor installation
bolts.
3. Contact the accelerator pedal arm to the stopper.
4. Turn the ignition switch to the ON position (but do not
start the engine).
5. Rotate the accelerator pedal position sensor with the knock
pin as the centre, and adjust the output voltage of the
accelerator pedal position sensor (1st channel) to the
standard value.
Standard value: 0.935 ± 1.135 V
6. Tighten the accelerator pedal position sensor installation
bolts fully.
