Keep your engine's timing accurate with the MotoRad 1KR101 Crankshaft Position Sensor, engineered to deliver OEM-level accuracy and dependable engine operation. This sensor uses a proprietary ferromagnetic material designed to hold up under extreme underhood temperatures while sending a precise voltage signal to your ECM, helping avoid misfires, stalling, and rough running caused by inaccurate crank position readings. Fluoroelastomer O-rings resist high heat and all common oil formulations, supporting long-term durability in demanding engine bay conditions. Manufactured in IATF16949-certified facilities, the 1KR101 fits a range of Isuzu, Cadillac, and Chevrolet applications from 1995-2003, including popular trucks and vans like the Astro, C/K series, Express, and Escalade. Backed by MotoRad's limited lifetime warranty, this sensor offers a straightforward, confidence-inspiring replacement for shops and DIYers looking to restore accurate crank signal performance without guesswork.
