Motorad 1KR157 Engine Crankshaft Position Sensor

The Motorad 1KR157 is a direct-fit replacement engine crankshaft position sensor engineered to restore precise ignition timing and fuel injection control. The crankshaft position sensor monitors crankshaft rotational speed and position, feeding critical data to the Engine Control Module (ECM) to manage spark timing and fuel delivery with accuracy.

Built as a Tier 1 OE-grade sensor, the 1KR157 is designed to match original equipment specifications, ensuring proper fitment and reliable operation without modification. Each sensor is constructed using proprietary ferromagnetic material that withstands extreme underhood operating temperatures while maintaining a precise voltage signal to the ECM. The internal winding uses enamel-coated ultrafine copper wire for superior heat protection and signal integrity.

Key Features:

• Tier 1 OE sensor design protects against power spikes and stray electromagnetic fields for accurate crankshaft positioning
• Proprietary ferromagnetic core material delivers a consistent, precise voltage signal to the ECM under extreme temperatures
• Fluoroelastomer O-rings provide superior resistance to high heat and all oil formulations for long-term durability
• Enamel-coated ultrafine copper wire winding for optimal heat protection and signal reliability
• Manufactured in IATF 16949 certified facilities to ensure consistent OEM-level quality
• Extensive product testing including salt spray, thermal vibration, high/low temperature impact, and static electricity testing
• Backed by a limited lifetime warranty
• Sold individually; no remanufactured components

The Motorad 1KR157 crankshaft position sensor is a dependable, factory-spec replacement that helps eliminate misfires, hard starts, stalling, and check engine light codes associated with CKP sensor failure.
