How to measure the condition of the Verna crankshaft position sensor?

[OJuliana]

The measurement method for the Verna crankshaft position sensor is as follows: 1. Check the normal gap between the crankshaft position sensor and the pulse wheel (target wheel), which should be greater than 0.5mm and less than 1.2mm. If the pulse wheel is improperly installed, being too large or too small, it may cause signal deviation; 2. Turn off the ignition switch, disconnect the crankshaft position sensor connector, and measure the resistance between terminal 1 and terminal 2 of the sensor, which should be between 400-600 ohms. If the value is not within this range, it can be determined that the crankshaft position sensor itself is faulty and should be replaced. The two signal wires of the crankshaft position sensor should be insulated from the shielding wire; 3. Turn on the ignition switch and measure the voltage between the two signal wires and ground, which should be 1.4V. This is the preset voltage from the engine control unit on the signal wires. When starting the engine, measure the signal voltage of the crankshaft position sensor, which should be close to 1.6V. If there is an open or short circuit inside the sensor, the signal wiring, or the engine control unit, the computer will be unable to receive the crankshaft position signal, resulting in the engine failing to start.
