Cel P1174

[Mile High VX]

Had my first CEL today...P1174 just as she turned over to 74K miles.

Gauge I used said it was a lean issue upon acceleration. I reset it and it has not come back. If it does, then I guess I'll start with a new fuel filter.

I use an injector cleaner with every other tank of fuel so that should not be the issue.

Any other thoughts would be appreciated.

Thanks.

If that doesn't work look at the following:

Clean the throttle body
Clean the MAF
Clean the MAS

Often the issues relating to rich/lean conditions have to do with gunked up sensors or the throttle body.

based on my experience with the Rodeo, the O2 sensors were a usual suspect

x 2...:_wrench:

MAF cleaning has always fixed that code for me.

Also, mine will occasionally throw that code when I get into the higher altitudes, even though I reset my CPU last time I was in Moab, it still popped a few times.

Thanks for the help...that's why it's so great to be here!
