Key Function: Supplies the Engine Control Module (ECM) with the primary timing reference for the engine, crucial for ignition timing and sequential fuel injection.
This is a Genuine OEM Crankshaft Position Sensor (CKP Sensor), identified by the Kia part number OK2B3-18-891. This sensor is a factory-original component designed for the legacy Kia Sephia and the first-generation Kia Sportage that utilized the earlier 1.8L and 2.0L gasoline engines.
The CKP sensor is critical for engine function:
Timing Signal: The sensor reads the rotation of the crankshaft's reluctor wheel, providing the Engine Control Module (ECM) with the necessary data for engine speed (RPM) and the precise piston position (Top Dead Center).
Reliability: For these older vehicles, installing a Genuine Part is the best way to ensure the sensor's signal output is stable and accurate, which is essential for preventing intermittent starting issues or stalling often associated with a failing CKP sensor (Diagnostic Trouble Code P0335).
Part Precision: While the part 0K2A6-18-891 is broadly interchangeable on some 1.8L Kia engines, OK2B3-18-891 is the specific Genuine OE number referenced for the applications you listed.
Fitment Assurance: The part number OK2B3-18-891 is verified as the correct genuine CKP sensor for the Kia Sephia and Kia Sportage 1999–2003 models with the corresponding 1.8L/2.0L engines.
