DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature

Do I need to put my 195 back in? I am running a non-Intense drilled 180*. Or an ECT sensor? It was mid-40s when I started driving this morning. Didnt really give it a good warm up, maybe a few more minutes in the morning now since Fall has finally hit in No. IL.? I think Im gonna plug up the fresh air scoop that I have for the CAI for the winter, also.

I get that code a lot, and I clear it out a lot.

If you get sick of it, put your 195 back in

I'm running a drilled 180* year round without issues, but I drilled a much smaller (1/16th I think) hole in it. When I had a larger hole, I would get that code.

I'll give 'er a couple few minutes in the driveway before I go. Its cleared, bought a nifty Actron pocket scan/eraser.

Never had that code ever and Im runnin 180.

Same with a drilled 180. (two 1/16 holes)
