What to know about the Crankshaft Position Sensor:
Most newer vehicles have computerized engine management systems that depend on sensors to report data to the on board computer. The vehicle crankshaft position sensor that is used in conjunction with the camshaft position sensor makes possible the control of ignition timing and informs the computer when to inject fuel and give spark sequence. Because of the mounting area of this sensor, it is no news for heat and oil leaks to cause this sensor to fail.
Facts to Note:
Damage to the crankshaft position sensor is sometimes produced by leaking oil, which means there may be another element of your vehicle that needs substitution or repair.
The electrical connector can also be hurt, and should be examined every time the position sensor is changed.
How to Fix:
Scan the car for trouble codes.
Take out and change crankshaft position sensor.
Clear trouble codes.
Check for the proper operation of the car.
The crankshaft position sensor will usually let you know when it needs changing. The Check Engine warning light will light up and you may notice that your vehicle has a hard time starting or running smoothly. When you notice any of these signs, schedule an inspection.
Common symptoms indicating you may need to change the Crankshaft Position Sensor:
Car does not start.
Check engine light is on.
Car misfires (car runs rough).
Importance of this service:
The crankshaft position sensor transmits critical information to your vehicle’s computer management system. The sensor offers the management system with the information required to control ignition timing, and it allows the computer know when it has to provide sparks and fuel. Without a functional crankshaft position sensor, the computerized management system will not receive this critical information, and the car will either not start, or will misfire during driving.
