What is the signal voltage of the Cruze intake cam position sensor?

Camshaft position sensor is a kind of sensing device, also called synchronous signal sensor. It is a cylinder discrimination and positioning device, which inputs the camshaft position signal to ECU and is the main control signal of ignition control. The method of measuring the camshaft position sensor is as follows:

1. Camshaft sensor is generally a three-wire Hall sensor, with power line 12v or 5v, signal line and ground line.

2. Unplug the plug, turn the key to two gears, and measure with a voltmeter to ensure that the power cord has voltage output. Use an electric meter to determine the ground wire, use a voltage block to connect one rice stick to the determined power line, and connect the other rice stick to the other two wires. The ground wire measures voltage, and the rest are signal wires.

How to diagnose and eliminate the fault of camshaft position sensor?

1. Check the high-voltage spark: pull out the high-voltage line of each cylinder, test the ignition of the cylinder, and check the intensity of the high-voltage spark. High-voltage sparks in each cylinder are normal.

2. Check the spark plug: the normal gap of the spark plug is generally 0.8mm, and the gap of the spark plug of the high-energy electronic ignition system is larger, reaching 1.2 mm ... After inspection, the gaps of the spark plugs are normal.

3. Check the air filter: clean the filter screen of the air filter and check whether the filter screen is damaged.
