Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Polaris 600 Switchback applications (approximately 2007-2013; verify submodel)
- Polaris 600 Switchback Pro-R / Adventure applications using 3131591

- Polaris 800 Switchback Assault / Pro-R applications using the same TPS
Product Overview
A Switchback that bogs as the throttle opens, idles unpredictably, or logs a throttle-position fault may have a worn sensor track. Frozen connectors, chafed wiring, throttle-cable adjustment, reeds, fuel pressure, and clutch load should be checked before the sensor is condemned.
The TPS gives the ECU a continuous throttle-angle signal. Correct base voltage and smooth sweep are required; simply bolting on the sensor without setting it can create a new drivability problem.
Match 3131591 or SM-01280, engine size, model year, connector, mounting ears, and throttle-body shaft. Use the Polaris-specific TPS setting tool or electrical procedure.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Will a new TPS cure every bog? A: No. Fuel, ignition, reeds, exhaust valves, clutching, intake leaks, and wiring can all cause bogging.
Q: Can I install it without setting voltage? A: That is not recommended. Base position and sweep should be adjusted or verified with the correct procedure.
Q: Does it fit every Polaris 600? A: No. This listing targets Switchback applications using 3131591/SM-01280.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
