Tianyi c5 electric throttle fault

1, the fault light is on, and the car shakes because:

(1) The fuel supply of the injector is not smooth, resulting in cylinder shortage (one cylinder is not working well);

(2) Poor ignition of spark plug, resulting in cylinder missing;

(3) Poor gas supply leads to poor combustion, insufficient engine power and car shake.

(4) Poor oil products lead to poor emission and unstable engine operation;

(5) The sensor and actuator work intermittently;

(6) Bad active contact of the sensor actuator circuit;

(7) Engine control module (ECM) works intermittently.

Because it is an intermittent fault, the fault is suspended after restarting and the car does not shake.

2. Because the engine control module (ECM) has stored the DTC, it is necessary to clear the DTC before the engine fault light goes out. The way to know the engine trouble code DTC is as follows:

(1) Remove the battery pile head and cut off the power supply;

(2) Use a computer diagnostic instrument to clear the fault code.
