- Check correct position of the sensor in its fitting.
- Check voltage between PINS 1-3 of the sensor. If there is no voltage, check continuity between PIN
1 of the sensor and PIN 3 of the instrument panel connector.
- Check the instrument panel PIN 13 connector.
- Check continuity with the sensor PIN 13 ground lead.
- Check continuity of the grey/white cable harness (cable harness side) from PIN 2 of the sensor to PIN
17 of the instrument panel connector.
- Check instrument panel PIN 17. If there is no failure after all these checks, replace the sensor.
Throttle position sensor
Function
In charge of telling the control unit the position of
the throttle valves.
Operation / Operating principle
The throttle valve position sensor works as a var-
iable resistance according to the throttle rotation.
Level in electrical circuit diagram:Throttle and
idle motor
Location:
Electrical characteristics:
PINS A-C: throttle closed approximately 1.7
kOhm; throttle open approximately 1.1 kOhm.
PINS A-B: approximately 1 kOhm.
Pin-out:
a: ground connection
B: supply voltage +5V
C: potentiometer signal (from 0.5 V with closed
throttle to 4 V with open throttle)
NAVIGATOR: PARAMETERS
Potentiometer on throttle / 0.5 (minimum) - 4 (full load)
Correct throttle position / 3.1 (minimum) - 85 (full load)
NAVIGATOR: STATUSES
Minimum/full load - ON/OFF
If the throttle is at minimum, it indicates ON, if the throttle is out of minimum, it indicates OFF
