Crankshaft Position Sensor for Mazda engines

This precision CKP sensor keeps your Mazda’s heart beating on time. It tells the ECU exactly where the crank is, so spark and fuel hit at the perfect moment. With a clean signal, you get easy starts, steady idle, strong pull, and lower fuel use .

Why this part is needed

The engine computer uses the crank signal to control ignition timing, injector timing, and misfire detection. Without a stable pulse, the ECU can’t sync the engine cycle, and performance drops fast.

How it works

Mounted near the crank pulley or flywheel, the magnetic/Hall sensor reads a toothed trigger wheel. As teeth pass the tip, the sensor generates a waveform. The ECU converts this into RPM and position, matching cylinders for precise timing ✅.

What happens if it fails

Symptoms include hard/no start, random stalling, rough idle, weak acceleration, poor economy, and a Check Engine Light (often P0335). In many cases, the engine will crank but never fire. Replace promptly to avoid misdiagnosis of coils or injectors ⚠️.
