It sounds like you have an electrical issue. Check the DTC connector to make sure you are getting power and ground. A short to ground could be the cause of this concern. It may be possible that the reverse safety switch has a pinched wire somewhere. Try unplugging the sensor to see if the fuse continues to blow. Electrical issues are tricky to figure out sometimes. If you need help with this, I suggest having a certified technician, like one from YourMechanic, determine the exact cause of your electrical issues.
