Product Overview
High-elevation riding makes a bad throttle signal obvious: the engine may hesitate, surge, idle high, or fall flat as the throttle moves. Before ordering a TPS, inspect the wiring where it flexes, verify fuel pressure, and look for intake leaks or throttle-body wear.
The sensor tells the ECU exactly how far the throttle is open. A smooth signal helps the controller meter fuel correctly, but the sensor must be aligned to the throttle shaft and set to the specified voltage.
Confirm model year, RMK submodel, engine, throttle body, connector, and 3131591. Calibration equipment or a suitable meter harness is required on many models.

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: Can TPS failure feel like a fuel problem? A: Yes. Both can cause hesitation or surging, which is why scan codes and a smooth voltage-sweep test are useful.
Q: Will it work on a Switchback too? A: The same reference appears on some Switchback models, but this listing and fitment list focus on RMK applications.
Q: What if the engine idles worse after installation? A: Stop and verify sensor indexing, calibration, throttle-cable free play, and connector pin fit.
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.
