What is the reason why Chery Tiggo's throttle suddenly doesn't respond?

Cause analysis of sudden non-response of Chery Tiggo throttle;

1, circuit:

A, acceleration sensor failure; Such as: sensor damage (open circuit short circuit);

B, throttle body failure; Such as: too dirty or stuck.

C, spark plug ignition failure; Such as: poor ignition or no ignition, resulting in no response to acceleration.

D, some switching appliances; For example, the connection parts of special vehicles, such as brake switches (signals), should be checked according to specific vehicles.

E, throttle position sensor failure; For example, the position sensor itself is damaged or the line fails to receive the signal.

F, ignition components such as distributor, high voltage package, high voltage line failure; For example, the leakage, aging, quality and other reasons of the above components cause poor ignition, and there is no response during acceleration.

G, stepper motor failure; Such as getting stuck or self-damaging.

2, machinery:

A, the throttle line is broken (old or low-end models)

B, the accelerator pedal or mechanical linkage is slack, and the idle distance is large (old or low-grade models).

C, throttle line and throttle installation, poor adjustment, slack, etc.

D. engine; For example, engine damage caused by abnormal cylinder pressure and improper maintenance.

3. Oil circuit:

A, the oil pressure is not normal; Such as abnormal oil pump pressure.

B, filter plug; Such as a clogged gasoline filter.

C. oil pipelines; Blockage or excessive impurities.

D. fuel injector; Self-quality failure or excessive foreign matter and impurities affect fuel injection or not.

E. fuel oil; Inconsistent labels, excessive moisture, excessive impurities, etc.

F, firewood filter or oil-water separator failure.

Operation:

1, such as human error driving: low speed and high slope, towing operation, etc.

2, due to improper maintenance of various parts of the vehicle, resulting in vehicle failure.

4. Oil circuit:
