How to Check the Crankshaft Position Sensor?
1 Answers
Here are the methods to check the crankshaft position sensor: 1. Determine by measuring voltage: Turn on the ignition switch and measure the voltage of the two signal lines to ground, which should be 1.4V. This is the preset voltage on the signal lines by the engine control unit. 2. When starting the engine, measure the signal voltage of the crankshaft position sensor, which should be close to 1.6V. 3. If there is an open or short circuit inside the sensor, signal lines, or engine control unit, the computer will be unable to receive the crankshaft position signal, and the engine will fail to start. Here is some related information about the crankshaft position sensor: 1. The function of the crankshaft position sensor is to determine the position of the crankshaft, i.e., the angle of the crankshaft. 2. The signal is calculated through the crankshaft position sensor and the camshaft position sensor, via the crankshaft position sensor.
