Detailed Description

Motorad 1KR101 is an OE-style crankshaft position sensor engineered to deliver accurate crankshaft position feedback for engine control systems. That signal helps the vehicle computer manage ignition timing and engine operation on applications such as Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe. This part cross-references AC Delco (e.g., 213283, 213308) for the same application.

Compatible With 1994-2007 Chevrolet, GMC, Cadillac, Oldsmobile, and Isuzu models listed in the fitment data, including Chevrolet Express 1500, GMC Savana 2500, Chevrolet Blazer, GMC Jimmy, Chevrolet S10, GMC Sonoma, and related GM trucks and SUVs. The 1KR101 part number is also a useful reference when matching replacement sensors for GM engine management service.

What It Helps Address

• Crankshaft signal loss that can trigger hard-start or no-start conditions
• Intermittent stalling caused by an unstable engine speed signal
• Rough running from incorrect crankshaft position input
• Check engine light concerns related to crankshaft sensor performance
• Driveability issues on Chevrolet Silverado 1500, GMC Sierra 1500, and similar GM platforms

Installation Notes and Tips

Verify connector shape, terminal count, and sensor body dimensions before installation. This sensor uses a female connector, male terminals, and a single mounting hole, so confirm the vehicle harness and mounting point match the original part. Inspect the connector and wiring for corrosion or damage before replacing the sensor.
