Peugeot 307.2.0 throttle is broken, under what circumstances will the fault light not light up?

0 1; The vehicle with electronic throttle is dirty, usually because there is too much carbon on the inside of the throttle, which will lead to the frequent lighting of EPC lights, and the vehicle will suddenly turn off and keep shaking when driving. Remove the throttle valve, thoroughly clean it, and then re-match it to eliminate the fault.

02; Once the electronic throttle control system fails and the engine limps home, the throttle valve plate can return to the high idle position under the action of the spring, so that the engine always keeps running at high idle speed.

03; Loose or poor contact of the accelerator pedal position sensor or the plug on the accelerator position sensor of the electronic accelerator system will interrupt the signal transmission between the computer and the accelerator pedal position sensor or the accelerator position sensor, thus lighting the electronic accelerator system warning light (EPC), and the accelerator pedal will feel empty.

04; When a throttle position sensor is damaged and the system uses the signal of another sensor, but the response to the accelerator pedal remains unchanged, only acceleration weakness, gear shift impact, cruise system shutdown, EPC light illumination and stored fault codes will occur.

05; When two throttle position signals are interrupted at the same time, the engine runs around 1500r/min, and there is no response when stepping on the accelerator pedal. The EPC light is on and the fault code is stored.

06; The signal of one accelerator pedal position sensor (potentiometer) is distorted or interrupted. If the other sensor is in the idle position at this time, the engine enters the idle state.

07; If the signal of the accelerator pedal position sensor is distorted or interrupted under load, the system will automatically enter an emergency operation state, at which time the engine speed will rise slowly and the maximum speed will be limited to120km/h/h..
