Where is the crankshaft sensor installed on the Nissan Sylphy?

[DeAdeline]

Nissan Sylphy's crankshaft sensor is installed on the flywheel side or the crankshaft pulley side of the engine. Principle of the crankshaft position sensor: 1. Provides ignition timing (ignition advance angle). 2. Confirms the signal of crankshaft position. 3. Used to detect piston top dead center, crankshaft rotation angle, and engine speed. The measurement method for the crankshaft position sensor is as follows: 1. Check that the normal gap between the crankshaft position sensor and the pulse wheel (target wheel) 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 that there should be 400-600Ω between terminal 1 and terminal 2 of the sensor. If the value is not within this range, it can be determined that the crankshaft position sensor itself is faulty and should be replaced. 3. Turn on the ignition switch and measure the voltage of the two signal lines to ground should be 1.4V, which is the preset voltage of the engine control unit on the signal lines. When starting the starter, measure 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, causing the engine to fail to start.
