Just went on a diet Saturday, stuff from no limit with GH tunes...

Anyways tossed a CEL on my way to work.i leave in the race tune. Truck had been running about 10 min when it came on(5min idle and 5 min light throttle getting to highway)
3/4 tank of fuel, 16* outside

Code is p0181-fuel temp sensor A circuit range/performance

I'm assuming it's literally because it's COLD outside but infifired I'd check with you guys.

Should i not use the hotter tunes when it's this cold out even if I'm driving like grandma?

Stock intake....

MAF/IAT will affect fuel temp readings?

The truck is running fine...i might have left that out

Mine will do the same thing when it is real cold out. Usually when in single digits. I have a '11 with GH. Tech told me there is a tsb for it and basically they lower the temperature parameters. So I just clear it when it happens.

Interesting, my truck went on a diet and now it is giving me this code 2 times in the last few trips. We are in the 60's to 80's when this thing came on.
Guess I should call No Limit then and see what they have to say..

I'm dealing with the same PO181 code on my 15 with GH SOTF tunes, getting the "we're working on it" line from No Limit when I call or email....

I was getting he P0181 code on mine and they could not explain it. Fuel Temperature Sensor A circuit range/performance. I was having a couple of issues.
They determined that the SOTF switch they sent me was old and not the right switch. They said I should have had a switch that said No Limit on it and my switch did not say that, so they sent me a new one and replaced it.
