What is the fault code p 16 12?

The fault meanings of different models of Pacific Auto Network p 16 12 are different. For example, Volvo, Chinese meaning: electronic throttle system has no signal, English meaning: electronic throttle system -nosignal. In the electronic throttle (ETC) system, the electronic control module (ECU) instructs the throttle position motor to optimize the throttle opening according to the signal from the accelerator pedal position (APP) sensor, engine speed, vehicle speed, air conditioning energy consumption, etc. ?

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic.

The composition of electric throttle can be roughly divided into the following parts: throttle, electromagnetic driver, potentiometer, controller (some of which are not directly managed by ecu) and bypass valve. Its fault characteristics are divided into two categories: hard fault and soft fault. Hard fault refers to mechanical damage, and soft fault refers to dirt, imbalance, etc. (Photo/Text/Photo: Pacific Auto Network Dong Peng)
