How to change the cruze sensor

When replacing the Cruze sensor, it should be replaced according to the replacement manual of different sensors. Automobile sensor is the input device of automobile computer system, which converts various working condition information in automobile operation, such as vehicle speed, temperature of various media, engine working condition and so on. , converted into electrical signals and transmitted to the computer, so that the engine is in the best working condition. The detection method of automobile sensors is as follows: 1. Unplug the plug, turn on the key for two gears, and measure with a voltmeter to confirm that the power cord has voltage output;

2. Use a meter to determine the ground wire, use a voltage block to connect one meter stick to the determined power wire, and connect the other meter stick to the other two wires. It is the ground wire that measures the voltage, and the rest is the signal wire;

3. At this point, turn off the key lead-out signal line, plug it back in and start the engine. Measure the signal wire and ground wire to see if there is a signal voltage whose output voltage should be less than the power supply voltage. If not, the sensor is basically broken.

4. While carrying out the above operation steps, check whether the signal teeth on the camshaft are in good condition, whether there are sundries between the camshaft sensor and the signal teeth, and whether the clearance is normal.
