Jimny slammed on the accelerator, and suddenly the speed was so high that he couldn't get on.

The reasons why the car doesn't accelerate when stepping on the accelerator: the dirty accelerator position sensor or unbalanced voltage will lead to the failure of the electronic accelerator, and it can't get on the accelerator when stepping on the bottom;

Because when you step on the accelerator, the cable will drive the accelerator, that is, the accelerator. There is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the signal pressure.

If the fault of electronic throttle is eliminated, then we should turn our attention to the three systems of engine intake, oil circuit and ignition. Just mentioned the throttle position sensor signal. In fact, it is a member of the air intake system, and the engine needs sufficient air for normal operation. The air intake system leaks or is blocked, the power drops when the car refuels, the speed can't go up, and the body shakes.

The oil system of the engine is also very important. If inferior gasoline is added, it is likely to lead to gasoline pump burning, three-way catalytic failure, piston failure and so on. , directly affect the engine power, easy to cause engine stall acceleration.

Finally, the ignition system. Generally, there are few problems with ignition high-voltage lines, so the main problems are ignition coils and spark plugs, because they are all wearing parts. When the performance of spark plug is degraded or inferior spark plug is used, it will lead to acceleration weakness and acceleration jitter.
