This is a brand new aftermarket crank position sensor, supplied as a direct replacement for the original unit fitted to Polaris Ranger, RZR and Sportsman machines. It is a plug-and-play, direct fit part with a single 3-terminal plug, so installation is straightforward and no wiring changes are needed. All products shipped are tested.
The crank position sensor tells the engine control unit exactly where the crankshaft is in its rotation. Without that signal the ECU cannot time ignition or fuel delivery, which is why a failing sensor typically produces hard starting, a no-start condition, cutting out at temperature, or intermittent misfiring that comes and goes with heat and vibration. This unit is built to the correct resistance specification so the ECU sees the same signal it expects from the original sensor.

Frequently Asked Questions
Does this sensor need any modification to fit?
No. It is a plug-and-play, direct fit replacement for the original unit, using the same single plug with 3 terminals and 3 wires. No cutting, splicing or adapters are required.
What is included?
You receive one brand new crank position sensor with its connector, tested before dispatch. Sealing washers, bolts and other fitting hardware are not included.
How do I confirm my old sensor has failed?
Measure the sensor with a multimeter. Yellow to white should read 560 ohms +/- 10%, and black to ground should read 0 to 0.5 ohms +/- 10%. A reading that is open circuit, shorted or well outside those figures confirms the sensor has failed. Faults that appear only once the engine is hot are typical of a sensor breaking down internally.
Will it fit both the Ranger and the RZR 800?
Yes, this sensor covers Polaris Ranger and Ranger Crew 700 and 800, RZR and RZR 4 800 and Sportsman 800 within the 2006-2017 span. Confirm against OEM number 2410720 stamped or listed for your original sensor before ordering.
