Engine Crank Position Sensor for Nissan

This sensor is a key input for the ECU to know exactly where the crankshaft is and how fast it’s turning. Without a clean signal, the engine cannot time fuel injection and ignition correctly. If you want stable starting, smooth idle, and proper power, this part is a must-have ✅

Why This Part Is Needed

It monitors crank rotation and sends a precise pulse to the control unit. The ECU uses it to synchronize spark timing, injector pulse, and misfire detection. It also helps maintain fuel economy and lower emissions

How It Works

A magnetic/Hall element reads a toothed wheel on the crank. As teeth pass the tip, the sensor creates a waveform signal. The ECU converts this into RPM and position data in real time ⚙️

What Happens If It Fails

A bad sensor may cause no-start, sudden stalling, long cranking, rough running, weak acceleration, and a check engine light. In severe cases the engine can cut out while driving, creating a safety risk ❗
