Lincoln Navigator Errattic DTe reading

[Bajaboy52]

Hi everyone,I have a problem,I have a 2003 Lincoln Navigator that has been giving very errattic readings on my DTE gauge.Now It's been to the dealer twice and they said that it had comtamined fuel so they put a fuel additive but to no avail.Then it went back in a they replaced the fuel sender after much complaining,and it has gotten somewhat better but still not fixed.Any suggestions would be greatly appreciated. Thank You.

Welcome! Sounds like its still under warranty which is good, I would try another dealer for a second opinion. Sorry I cant help more, sometimes it is a bad ground on the fuel tank to cause skewed readings, but this system is alot more sophisticated.

I am also thinking a wiring issue, probably in the ground circuit as V8_Dave said but I am not too familiar with the Navi's. Certainly take it to another dealer though and don't just settle for the standard "that is normal for this model" BS that a lot of dealers like to throw at problems. Good luck.
