Where is the Crown Crankshaft Sensor Installed?

[LeLaura]

The Crown crankshaft position sensor is located inside the air conditioning compressor and can be seen by removing the lower cover. Below are the specific measurement methods for the crankshaft position sensor: 1. Check the normal gap between the crankshaft position sensor and the pulse wheel, which should be greater than 0.5mm and less than 1.2mm. If the pulse wheel is installed incorrectly, 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 400Ω and 600Ω. If the reading 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 are insulated from the shielding wire. 3. Turn on the ignition switch and measure the voltage of the two signal wires to ground, which should be 1.4V. This is the preset voltage from the engine control unit on the signal wires. When starting the engine, the signal voltage of the crankshaft position sensor should be close to 1.6V. If there is an open or short circuit inside the sensor, signal lines, or engine control unit, the computer will not be able to receive the crankshaft position signal, resulting in the engine failing to start.
