What is the reason why Nissan Teana didn't respond when stepping on the gas pedal?

According to different models (designs) and different fuel modes, there are many possibilities:

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.

Mechanical:

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.

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.

It is not excluded that there are more possibilities, depending on the actual vehicle detection and judgment results.
