What to know about the Crankshaft Position Sensor:
Many newer cars have computerized engine management systems that rely on sensors to report data to the computer. The crankshaft position sensor is used in conjunction with the camshaft position sensor to control ignition timing and to let the computer know when to inject fuel and provide spark sequence. Due to the mounting locations of this sensor, it is common 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 provides the management system with the information it needs to control ignition timing, and it lets the computer know when it needs to provide sparks and fuel. Without a functioning crankshaft position sensor, the computerized management system doesn’t receive this critical information, and the vehicle will either not start, or will misfire while you’re driving it.
