Detect camshaft sensor?

The camshaft position sensor is also known as the engine speed, and it can also be called the crank angle sensor. Its main function is to collect the signal sent by the sum of the rotation angle of the crankshaft and the engine speed, and the engine The emitted signal is input into the ECU, and this signal is used to determine when the engine is ignited or injected. This article is mainly to teach you how to detect the camshaft sensor.

Camshaft sensor detection

Camshaft position sensor maintenance method is as follows:

1. When there is a problem with the camshaft position sensor, we can first check whether the resistance of the coil of the camshaft sensor has failed. First, we need to disconnect the ignition switch, just unplug the tactile sensor from the socket, and then use the resistance level of the multimeter to check whether the resistance value of each port meets the standard setting value. If the detected resistance is not If it meets the standard value, we need to replace a sensor assembly.

When the detection port is terminal NE-terminal G, the standard value in cold state is 155-250, and the standard value in hot state is 190-200; when the detection port is terminal G1-terminal G, cold state The standard value in the state is 125-200, the standard value in the hot state is 160-235; when the detection port is terminal G2-terminal G, the standard value in the cold state is 125-200, and the hot state The standard value below is 160-235. ;

2. When there is a problem with the camshaft position sensor, we can check the signal voltage of the camshaft sensor. First of all, we need to put the multimeter on the voltage position, and then put the multimeter on the No. 1 terminal of the sensor and on the No. 3 terminal. When the engine starts, the voltage value should be 0.2V- Within the range of 1.2V, when the engine rotates rapidly, the voltage value should be within the range of 1.8V-2.5V;

3. When detecting the circuit of the synchronous signal of the camshaft sensor, first we need to disconnect the connector inside the sensor, then switch the ignition switch to the "ON" state, and then start to check between the terminal A and terminal C of the sensor The normal voltage value should be 8V, but when the engine starts to rotate, we need to check the voltage between the terminal B and terminal C of the sensor. The voltage value should alternate between 5V and 0V.
