What color is the plug of Regal 2.4 intake camshaft position sensor?

The Buick Regal camshaft sensor is located above the valve cover on the timing cover. Failure of camshaft sensor will lead to vehicle weakness and increase fuel consumption; If the camshaft position sensor is broken, the computer will spray oil out of order, resulting in oil waste, broken track and speed failure. The fire broke; The camshaft position sensor can determine the ignition sequence. If it breaks down, the ignition won't work and the engine won't start easily. The measurement method of camshaft position sensor is as follows:

1. Camshaft sensors are generally three-wire Hall sensors, 12v or 5v power lines, signal lines and grounding lines.

2. Unplug the plug, open the second gear with the key, and measure with a voltmeter to ensure that the power cord has voltage output. Use an ammeter to determine the ground wire, use a voltage block to connect one ammeter pole to the determined power line, and connect the other ammeter pole to the other two wires. Measure the ground strap voltage, and the rest are signal wires.

3. At this point, turn off the key to lead out the signal wire, plug in the plug to start the engine, and measure whether there is signal voltage between the signal wire and the ground wire, and the output voltage should be less than the power supply voltage. If there is no signal voltage, the sensor is damaged.
