A electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft while this information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

• 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 operations in your fuel injection and ignition systems. The crankshaft sensor sends information to your Nissan’s engine control unit (ECU). Afterwards, the ECU uses this data to orchestrate the movements of engine components.

Without a working crankshaft, your Nissan engine may act up. A few signs you have a worn Engine Crankshaft Position Sensor include misfires, dashboard signals, engine knocking sounds, engine stopping unprompted, and irregular acceleration.

Crankshaft sensors do not need to be replaced regularly. They only need to be serviced according to your Nissan’s manual and replaced as-needed, if issues arise. Most of the time, a motorist’s Engine Crankshaft Position Sensor malfunctions due to damage resulting from overheating, failing circuitry, or issues in other engine components, like the timing belt.

Have you been noticing weird sounds, misfires, or irregular acceleration in your Nissan? If that’s the case, you may need to replace your Engine Crankshaft Position Sensor. Visit your nearest Nissan service center for a convenient inspection and diagnostics. If a new Engine Crankshaft Position Sensor is necessary, be sure to replace it with an authentic Nissan replacement part. Remember that the ECU depends on the crankshaft sensor to ensure your Nissan’s engine delivers the efficiency and performance you expect.
