Yamaha Pulls Over 12,000 Bikes in Germany Due to Faulty ECU Sensor

If you’re riding a Yamaha MT-09, MT-10, Tracer 9 GT, XSR900, or even the quirky three-wheeled Niken GT, you might want to pay attention. Yamaha has issued a massive recall in Germany, affecting over 12,000 motorcycles due to a throttle position sensor (TPS) issue caused by faulty ECU programming. 

What’s the Issue?

The problem affects eight different Yamaha models built between May 2021 and December 2024. Due to incorrect ECU calibration, the TPS can wear prematurely, leading to potential debris buildup at the contact points. This can cause the engine to stall unexpectedly, even at idle. Worse still, the malfunction could happen at irregular intervals, meaning riders could experience their bike cutting out mid-ride. The warning light might pop up with error code P2135, but that’s not a guarantee.

What’s Yamaha Doing About It?

To fix the issue, Yamaha has put together a recovery plan that includes:

✔ A full ECU software update – recalibrating the control unit to fix the faulty programming.
✔ TPS replacement – if your bike has already been ridden, Yamaha will swap out the throttle position sensor entirely.
✔ TPS reset – recalibrating the sensor to factory specs to prevent further issues.

The recall is being carried out in collaboration with the Federal Motor Transport Authority (KBA), which is tracking down affected owners and issuing official notices.

Is Your Bike Affected?

The MT-09, MT-09 SP, Tracer 9 GT, and Tracer 9 GT+ are the most impacted models, while the Niken GT appears to be the least affected. If you own one of the recalled bikes, you’ll get the fix completely free of charge at your local Yamaha dealer. The repair is expected to take around two hours, so no major downtime.

If you’re in Germany and haven’t received a recall notice yet but own one of the models mentioned, it’s worth checking with your dealer to see if your bike is on the list.
