Detailed Description

The Motorad 1KR111 crankshaft position sensor monitors crankshaft position data used by the engine control system to manage ignition timing and fuel delivery. This sensor is specified for Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Ford Mustang, Mazda B4000, Mercury Mountaineer, and Ford Explorer Sport applications across model years 1997 through 2011. If you are replacing a failing crankshaft position sensor on a Ford Ranger or Ford Explorer, this part number 1KR111 provides an OE-style service replacement with the correct connector shape, terminal layout, and mounting configuration.

This part cross-references Ford/Motorcraft applications such as F87E6C315AA and F87Z6C315AA for the same application.

What It Helps Resolve

• Crankshaft signal loss that can trigger stalling or no-start conditions
• Rough idle caused by inconsistent engine speed input
• Intermittent misfire concerns related to timing signal errors
• Hard starting when the engine control module cannot read crankshaft position correctly
• Check engine light concerns tied to crankshaft position sensor faults

Installation Notes and Tips

Verify connector style, terminal count, and mounting hole layout before installation. This sensor uses a rectangular female connector with blade terminals and does not include a wiring harness or mounting bracket. Confirm the vehicle’s original sensor location and compare the old part to Motorad 1KR111 before replacement.
