Engine Light
You started a new thread and didn't say it was in reference to a previous one? Well, how were the readers here supposed to know that?
I'm a pretty smart guy mechanical wise.
But....I'm not a mind reader.
I like to help folks out with any car problems if I can. It would help if your posts were a little clearer.
And FWIW. You still haven't posted the year, engine etc.

I have had the same indication on the display (data unavailable). The solution was to unplug the upper MAP sensor and re-plug it in fully. Do this with the engine off. It may have been bumped during an oil filter change. If that doesn't do it, you most likely have poor connections where the GMTU pigtails were spliced in. My 2010SS had connection problems and the dealer removed the connectors and soldered the wires for both the upper and lower TMAP's. Try the unplug/re-plug thing first, it's cheap.
