CHECKING THE THROTTLE POSITION
SENSOR
1. Remove:
• Throttle position sensor
(from the throttle body)
EWA16690
WARNING
• Handle the throttle position sensor with
special care.
• Never subject the throttle position sensor
to strong shocks. If the throttle position
sensor is dropped, replace it.
2. Check:
• Throttle position sensor maximum resistance
Out of specification → Replace the throttle
position sensor.
Resistance
2.64–6.16 kΩ

NOTICE
Pay attention to the installing direction of the
test harness S– pressure sensor (3P) cou-
pler.
b. Connect the digital circuit tester (DCV) to the
test harness S– pressure sensor (3P) "a".
• Positive tester probe
Pink/white (wire harness color)
• Negative tester probe
