Don't pay for a new sensor until whomever works on it has verified that the wiring between the sensor and the voltage supplied to the sensor is correct, and that the original sensor is in fact defective. A simple resistance check of the sensor with an ohmmeter will take only a minute after gaining access to it, you do not even have to remove it from the tank to check it. If possible, tell whoever is doing the work that you will authorize doing the work to actually remove and replace the sensor only after he has actually verified that the problem is not the external wiring to the PCM or that the sensor failed a resistance check with it installed in the tank. If they don't agree to this than go find someone else who knows how to properly troubleshoot electrical issues.
Thanks for the advise. I will talk with my tech who is also by best friend for over 12 years. He will do what I say and suggest, lol.
