Detailed Description

Motorad 1KR108 is an engine crankshaft position sensor designed to deliver accurate crankshaft signal input for the engine control system. That signal helps the vehicle computer manage ignition timing and engine operation across many GM platforms, including Chevrolet Cavalier, Malibu, Cobalt, HHR, Trailblazer, and GMC Envoy applications. It also serves select Saturn, Pontiac, Buick, Oldsmobile, Saab, Isuzu, and Geo models where the original sensor uses the same connector and mounting style.

This part cross-references common replacement numbers such as 213319 and 213366 for the same application. If you are replacing a failing crankshaft sensor on a Chevrolet Trailblazer, Saturn Vue, or Pontiac Grand Am, 1KR108 provides a direct replacement option with the correct connector shape and terminal layout.

What It Helps Fix

• Crankshaft position signal loss
• Hard starting or no-start conditions
• Intermittent stalling
• Rough engine operation caused by incorrect timing input
• Check engine light concerns related to crankshaft sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and mounting hole location before installation. This sensor uses a female oblong connector with blade terminals and does not include a wiring harness or mounting bracket. Confirm the original sensor style on the vehicle before ordering, especially on Chevrolet Malibu, Saturn Ion, and GMC Envoy applications.
