Why Replacement is Important:

A properly functioning crankshaft position sensor is vital for accurate engine timing and combustion control. If this sensor fails, the ECU may receive incorrect crankshaft position data, leading to misfires, rough idling, hard starting, stalling, or engine failure. Faulty signals can disrupt fuel injection timing and ignition timing, reducing performance and fuel efficiency. Replacing worn or defective sensors ensures stable engine operation, preserves drivetrain health, and prevents costly repair bills. Regular inspection and timely replacement help maintain optimal engine performance and reliability.
