Hello. My name is ***** ***** I will be helping you today.

Unfortunately there isnt anything you can do aside from get it to a dealer or shop that can do programming. There is a software update to address this. Wish I had some better news for you. Keep it running till you get somewhere it can be fixed is about all I can say. It can idle till it runs out of fuel. LOL.

Let me know if you need anything further.

Please be sure to rate my service so I get credit for helping you today. THanks

i guess i wanted to know if the sensor was digital or analog, the signal must be able to be intercepted somewhere, between the tank and the ecu. so i just wanted to know hopefully that it was something i could fool till i got it to the dealer
