What should I do if the voltage of Buick gl8 throttle position sensor is low?

Low voltage of throttle position sensor is generally an internal circuit fault caused by unclean throttle, which can be solved after cleaning, or consult local dealer for inspection and maintenance.

Automobile sensor is the input device of automobile computer system, which converts various working condition information in automobile operation, such as vehicle speed, temperature of various media, engine working condition and so on. , converted into electrical signals and transmitted to the computer, so that the engine is in the best working condition. There are many sensors on the vehicle. When judging the fault of the sensor, we should not only consider the sensor itself, but also consider the whole faulty circuit.

There are two pairs of contacts inside the throttle position sensor: idle switch contact and full load switch contact. When the engine is idling or forced idling, the idle contact is closed, and the electronic control unit finely adjusts the mixture at idle speed according to this signal, corrects the ignition advance angle, and cuts off the exhaust gas recirculation system; When forced idling, temporarily cut off the oil supply. When the throttle opening exceeds a certain angle, the full load contact is closed, and the electronic control unit adds rich mixture according to this signal to improve the output power of the engine.
