It’s a well know issue that the crankcase pressure sensor and the ambient pressure sensor tend to fail on all KTM, Husky, and Gas Gas TPI fuel injected two stroke motorcycles. We have even seen some bad sensors on brand new bikes with zero hours. If you own a TPI bike, you should have one of these sensors as a spare in your tool box. This sensor is a genuine OEM part and has the same part number for both the crank case pressure sensor and the ambient pressure sensor. This sensor does not suite 2023 and on TBI model bikes.
