9000 CDE V6-2962cc 3.0L DOHC (B308) (1995)
Throttle Position Sensor: Description and Operation
The position sensor consists of a potentiometer connected to the throttle shaft.
The sensor is supplied with a 5 V from pin 12 and grounded via pin 30 of the control module. The voltage from the sensor is connected to pin 53
of the control module and is proportional to the throttle opening.
The voltage is approx. 0.5 V during idling and approx. 4.5 V at wide open throttle. The ECM uses the voltage from the sensor to identify idling,
partly open throttle and wide open throttle. During idling the ECM uses a special ignition control matrix and adjusts the idling speed.
