Start the engine, and the data stream shows that the engine has no speed, which is the problem of the speed sensor.

1, sensor is bad;

2. The gap between the cam position and the sensor is too large;

3. Poor wiring of the sensor (plug contact);

There is a very simple way to judge. If there is an oscilloscope, if there is no oscilloscope, disassemble the crankshaft position sensor, then plug it in, and use the key to send electricity to the on position.

When measuring the sensor output with multimeter, it should be+12V+ 12V.

There are pliers or a board close to the sensor, and the output voltage of the sensor changes, ranging from 0V to 12V, indicating that the sensor is good. If there is no change, the sensor is broken.

According to your account, there should be no problem with the sensor, so check it carefully.

2. The gap between the cam position and the sensor is too large;

3. Poor wiring of the sensor (plug contact);

This problem should be solved.
