Throttle position (TP)

Throttle Position Sensor - a variable resistor with the rotary axis of the throttle and transmits the information based on which the ECM determines when the throttle is closed, fully open or in intermediate positions. The sensor is rigidly connected to the throttle shaft. Depending on the throttle position sensor resistance changes.

Check

PERFORMANCE ORDER

1. Unplug the connector from the throttle position sensor.

2. Measure the resistance between terminals 1 (mass) and 2 (power) sensor connector for 2.0 l DOHC engine or between terminals 2 (weight) and 1 (power) sensor connector Engine 2.5L V6.

Resistance: 3.5-6.5 ohms

3. Connect an ohmmeter to terminals 1 (mass) and 3 (sensor output) sensor connector for 2.0 l DOHC engine or between contacts 2 (w) and 3 (sensor output) socket of the gauge for the engine 2.5 liter V6.
4. Slowly open the throttle and check that the resistance of the sensor changes smoothly in proportion to the throttle.
5. If the sensor resistance is not correct, or change abruptly, replace the sensor.

Tightening torque: 1.5-2.5 N ??? m
