• Part of your vehicle's fuel injection and ignition systems


• Monitors the engine's many moving parts


• May need to be replaced if Check Engine Light is on

The Engine Crankshaft Position Sensor supports functions in your car’s ignition and fuel injection systems. This sensor sends information to your INFINITI’s engine control unit (ECU). In turn, the ECU leverages this data to direct movements of the corresponding engine components.

Without a functional crankshaft, your INFINITI engine may act up. A few signs you have a worn Engine Crankshaft Position Sensor are dashboard warning lights, knocking sounds, engine misfires, engine stopping unprompted, and irregular acceleration.

Crankshaft sensors do not need to be replaced regularly. They only need to be serviced according to your INFINITI’s manual and replaced as-needed, if issues arise. Most commonly, an Engine Crankshaft Position Sensor fails due to damage resulting from overheating, failing circuitry, or problems with other engine parts, such as the timing belt.

Are you noticing knocking sounds, engine stalling, or irregular acceleration in your INFINITI? If so, you may need a new Engine Crankshaft Position Sensor. Visit your local INFINITI service center for a convenient inspection and diagnostics. If a replacement Engine Crankshaft Position Sensor is needed, replace it with an authentic INFINITI replacement part. Don’t forget that the ECU depends on the Engine Crankshaft Position Sensor to ensure your vehicle’s combustion engine top-notch performance and fuel efficiency.
