Throttle Sensor Defect Prompts Recall of Yamaha Motorcycles

More than 200 Yamaha motorcycles sold in Hawaii are being recalled due to a defect in the Throttle Position Sensor (TPS) that could lead to engine stalling and increase the risk of crashes. The recall, submitted to the National Highway Traffic Safety Administration by Pure Sports Distributing Inc., applies to a range of Yamaha models manufactured between February 2021 and March 2025.

The issue involves excessive movement of internal brushes within the TPS, which is triggered by improper programming of the Engine Control Unit (ECU). Over time, the abrasion created by this excessive sliding results in particle buildup at the sensor’s contact points. This malfunction can cause erratic engine idling or engine failure during operation, potentially leading to loss of vehicle control and severe accidents. Affected models include the Yamaha Tracer 9 GT, MT-09 SP, MT-09, MT-10 SP, MT-10, and XSR900.

A malfunction indicator light and fault code P2135 will alert riders to the issue. In March 2025, Yamaha Motor Co., Ltd. informed Pure Sports Distributing Inc. about the condition following internal testing and quality review. By April, Yamaha had made replacement parts available and fulfilled necessary orders for dealers in Hawaii.

To resolve the defect, Yamaha will conduct a Factory Modification Campaign involving both a TPS replacement and ECU reprogramming. The repair, which takes up to 90 minutes depending on the model, will be performed free of charge to owners. The recall affects all 216 motorcycles identified, with each unit confirmed to have the defect. Production programming has already been updated to correct the issue in new units.

Notifications to dealers and owners are scheduled to begin following regulatory approvals. Owners who provided email addresses during registration have already received preliminary outreach, and physical notices will be mailed within the required 60-day window.
