CHECKING THE ACCELERATOR POSITION
SENSOR
1. Remove:
• Accelerator position sensor
(from the throttle body)
EWA2S31017
WARNING
• Handle the accelerator position sensor with
special care.
• Never subject the accelerator position sen-
sor to strong shocks. If the accelerator po-
sition sensor is dropped, replace it.
2. Check:
• Accelerator position sensor maximum resis-
tance
Out of specification → Replace the accelera-
tor position sensor.
