Product Description
This is a genuine OEM Hyundai & Kia Crankshaft Position Sensor with part number 39180-03000 / 3918003000. Also known as the CG25 LJ12 sensor, this critical engine component detects the position and rotational speed (RPM) of the crankshaft, sending data to the Engine Control Module (ECM) for precise ignition timing and fuel injection control.
What is a Crankshaft Position Sensor?
The Crankshaft Position Sensor (CKP) is one of the most important sensors in your vehicle's engine management system. It monitors the position and speed of the crankshaft and sends this information to the ECM. Without accurate CKP data, the engine cannot start or run properly.

- ✅ Exact Replacement – Matches original factory specifications
Functions of Crankshaft Position Sensor:
- 🔧 Ignition Timing – Controls spark plug firing sequence
- ⛽ Fuel Injection – Manages fuel delivery timing
- 📊 Engine RPM – Monitors crankshaft rotational speed
- 🔍 Misfire Detection – Identifies engine misfires
- ⚡ Camshaft Sync – Coordinates with camshaft sensor
Common Symptoms of Faulty Crankshaft Position Sensor:
- ⚠️ Engine cranks but fails to start
