Where is the Sonata Crankshaft Position Sensor Located?
1 Answers
Sonata's crankshaft position sensor is installed near the pulley. The working principle of the crankshaft position sensor is to provide ignition timing (ignition advance angle) and confirm the signal of crankshaft position, which is used to detect the top dead center of the piston, crankshaft angle and engine speed. The function of the crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of the crankshaft and the engine speed. The following is the introduction of the measurement method of the crankshaft position sensor: 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, too large or too small, it may cause signal deviation. 2. Turn off the ignition switch, disconnect the crankshaft position sensor plug, and measure that there should be 400~600Q between terminal 1 and terminal 2 of the sensor. If it is not within this range, it can be determined that the crankshaft position sensor itself is faulty and the sensor 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 line. When starting the starter, the signal voltage of the crankshaft position sensor should be close to 1.6V. If the sensor is internally open or short-circuited, the signal line is open or short-circuited, or the engine control unit is internally open or short-circuited, the computer will not be able to receive the crankshaft position signal, which will cause the engine to fail to start.
