The car suddenly stepped on the accelerator, which was useless. Just turn it off and restart it. What is the reason?

The throttle is out of order, and now the throttle of many cars is electronic, not the previous cable. The electronic accelerator needs to transmit the signal of the accelerator pedal in the car to the computer, and now the computer feeds back to the accelerator motor to drive the accelerator plate. The switch size of the sign is the level of the tachometer. The larger the throttle opening, the more air intake and the higher the vehicle speed.

The solution is as follows:

Just change the transmission oil once The corresponding inspection method is not difficult, just drive to a shop with trusted technicians and ask them to check the gearbox for you.

If the problem is not solved after the oil change, don't unpack it yet. If there is a problem with one of the four-wheel speed sensors, it will also give a high error message to the driving computer, thus forming a fault code and affecting gear shifting.

If it is a speed sensor, it is easy to say. I remember that one was only about 500 RMB, and the disassembly time was not long, so it was acceptable to repair it. If the fuel tank becomes particularly dirty due to the addition of bad fuel, it should be cleaned and removed.
