The jeep Compass crankshaft position sensor is located at the lower right of the automobile engine, that is, the joint between the gearbox and the engine oil pan.
Jeep guide crankshaft position sensor is usually installed at the front end (pulley) of the crankshaft, and the rear end of the crankshaft is near the big flywheel or in the middle of the crankshaft. It is one of the most important sensors in the control system.
Its main function is to detect the engine speed, so it is also called speed sensor; It detects the top dead center position of the piston, so it is also called top dead center sensor, which includes detecting the top dead center signal of each cylinder for controlling ignition and detecting the top dead center signal of the first cylinder for controlling sequential fuel injection.
Extended data
When the jeep compass crankshaft position sensor fails, it will have the following performance:
1, the car has a high-pressure fire, but it takes a long time to start, and the car can finally run.
2. During the starting process, the crankshaft will rotate reversely, and the intake manifold will backfire.
3. The idle speed of the car is unstable and the jitter is serious, which is similar to the cylinder failure of the car.
4, the car acceleration is weak, the car can't run, and the speed is better than 2500 rpm.
5, the car will have high fuel consumption, exhaust emissions exceed the standard, and the exhaust pipe will emit unpleasant black smoke.
