Problem overview

Some Suzuki Reno owners report experiencing issues with the Throttle Position Sensor (TPS), particularly when encountering a P0122 trouble code. These problems may necessitate resetting the Transmission Control Module (TCM) fuse to help resolve the issue. Owners have found that locating the fuse box, removing the TCM fuse for about 30 seconds, and reinserting it can be effective. After this reset, some owners recommend letting the vehicle idle for a few minutes and then taking it for a test drive to assess acceleration and shifting performance. It is advised to drive the vehicle under various conditions to confirm that the TPS issue has been addressed.
