Engine Crankshaft Position Sensor for Nissan

This engine timing sensor is a must-have part for stable starting and smooth running. It monitors the crankshaft speed and position, then sends a precise signal to the ECU so fuel injection and ignition happen at the right moment ⚙️. When the ECU knows exactly where the crank is, the engine can fire cleanly, idle steadily, and deliver good fuel economy ⛽.

Why this part is needed

Modern Nissan engines rely on accurate crank feedback to control spark timing, injector pulse, and misfire detection. Without a clean signal, the computer can’t “sync” the engine rotation correctly.

How it works

The sensor reads a toothed trigger wheel on the crankshaft. As the teeth pass, it creates a digital pulse pattern. The ECU converts these pulses into RPM and position data, then adjusts ignition and fueling in real time ?.

What happens if it fails

A faulty unit may cause no-start, random stalling, rough idle, hesitation, or poor acceleration. You may also see a check engine light, extended cranking, or sudden cut-out while driving ?. If ignored, it can lead to misfires, higher fuel use, and catalytic converter stress.
