Genuine OEM Engine Component (Hyundai-Kia MOBIS Original Equipment).
Part Number: 39180-23000 (Official Hyundai OE Number).
Interchangeable with: This number is often cross-referenced with 39180-26900 and 39180-22090, depending on the specific engine version.
Component Name: Crankshaft Position Sensor (CKP Sensor) (Magnetic Induction Type).
Primary Applications (Engine Specific): This sensor is crucial for Hyundai and Kia vehicles equipped with the 1.8L and 2.0L BETA (G4GF/G4GC) or 1.6L ALPHA II (G4ED) Gasoline engines:
Hyundai Elantra (XD Chassis): Fits the 1.8L and 2.0L models (approx. 1999–2006). This confirms your Elantra XD 2004.
Hyundai Tiburon / Coupe (RD/GK): Fits 1.8L and 2.0L models (approx. 1997–2001).
Kia Rio / Rio5: Fits 1.6L models (approx. 2006–2011) that use the related Alpha II engine.
Key Function: Provides the Engine Control Module (ECM) with the primary timing reference for the engine, absolutely vital for controlling ignition timing and fuel injection.
This is a Genuine OEM Crankshaft Position Sensor (CKP Sensor), identified by the Hyundai/Kia MOBIS part number 39180-23000. This sensor is a factory-original component primarily used on the Hyundai Elantra XD chassis, which typically uses the 2.0L DOHC Beta engine for the 2004 model year.
The Crankshaft Position Sensor is the most critical input for the engine control unit:
Engine Speed and Position: The sensor is a magnetic induction type that reads a tone wheel (reluctor) on the crankshaft. This provides the ECM with the engine speed (RPM) and the precise rotational position of the crankshaft.
Timing Control: The ECM uses this information as the foundational reference point to calculate the exact timing for spark plug firing and sequential fuel injection, ensuring the engine runs efficiently.
Reliability: Using the Genuine part ensures the correct voltage signal type and high-quality internal components, which is critical for preventing common fault codes like P0335 (Crankshaft Position Sensor Circuit Malfunction).
Fitment Assurance: The part number 39180-23000 is verified as the correct genuine CKP sensor for the Hyundai Elantra (XD chassis) 2.0L Beta engine for the 2004 model year.
Compatible Vehicle (Primary Applications - Check VIN for confirmation of 1.8L / 2.0L Beta Engine):
Hyundai Elantra (XD) 1.8L / 2.0L (approx. 1999–2006)
Hyundai Tiburon 1.8L / 2.0L (approx. 1997–2001)
Kia Rio / Rio5 1.6L (approx. 2006–2011)
