P0128 Code thrown...

Check engine light came on yesterday during a 2 mile round trip to the grocery store.

Read it when I got back (P0128) and it looks like a coolant thermostat issue.

I erased it and will see if it comes back...but...

Anyone else had this fail? I just tripped 46k two days ago.

More common than you think. No big deal. Get your IC Pump changed out while you're doing the job and kill 2 birds with one stone, because if you haven't already I bet that thing's on it's way out.

Maybe that grill is blocking the airflow! LOL JK, I know how sensitive you are about your grill!

You guys can all suck it!

Just so you know, I did a baseline dyno run the other day with my factory grille...and then tried it with my super-awesome totally rad grille that you guys are all jealous of and here's the result:

Yeah. So there. My grille adds 30 HP!!

Now. Back to the real issue.

Sounds like replacing that sensor...if you do actually have to remove the s/c...is a total pain in the ****.

Hopefully, someone posts helpful insight in getting rid of the problem once and for all.
