What are the common faults of EFI diesel vehicles and how to solve them?

1. Idle switch is not turned off. We can turn on the car air conditioner first and then turn the steering wheel. At this time, if the engine speed remains unchanged, it means that there is something wrong with the automobile engine. Solution, in this case, we can adjust the throttle sensor of the car or even replace it seriously.

2. The fuel injector drips oil or the fuel injector is blocked. In this case, don't just try to make sure there is no problem. Try to determine whether the problem is trying to find a solution. In this case, quasi-professionals are usually needed to do it. If you use a computer to check, the computer will think it is an oxygen sensor problem. If you use a stethoscope, you will hear a creaking sound. If the injector does not move and there is no sound after inspection, it is a problem and should be repaired in time.

3. Engine jitter. There is a pressure sensor in the valve distribution stage. Failure in this place will increase the temperature of the intake pipe, lead to the loss of some heat-resistant parts of the engine, and the engine will have unstable idle speed and jitter. This fault solution is quite simple and needs to be readjusted.

It won't catch fire. The reason for this failure is that the oil pump installation is not matched. If this kind of fault occurs, we only need to reinstall the oil pump to return to normal. Of course, if the installation technology is not up to standard, it is recommended not to install it yourself. In case this problem leads to another one, it will be troublesome.

5. There is no response when stepping on the accelerator. We can try to turn off the power of the car by using the door first to see if there is any poor contact. If not, the car will have a self-check process, just like the computer is turned on, and there will be a few seconds of inspection. We will turn on the power supply, start the engine in 5 seconds, then step on the accelerator immediately, and return to normal in a few seconds.
