ERROR CODE P0128!!!

Civicsi19 · Dec 22, 2019

I have a 19' SI sedan. Mods are, Greddy Catback, HPS intake pipe, K&N drop in filter, AEM upper intercooler piping, E85 flex fuel kit(tuned), Perrin rear motor mount insert, Eibach Sportline springs, 20mm spacers all around. So my issue is this. My car is on about an E40 mix give or take and I keep getting this P0128 code on my dash. Its very annoying and I want to know if there is a way to make this go away. I looked up this code and its stating that the engine coolant isn't getting up to temperature quick enough. I live in Miami, FL so its not like I am in cold climate whatsoever. I do remember removing a sensor down at the bottom of the radiator where I had to connect a plug from the

you can check connector wires in the plug that can become brittle with age & break.

You need to toggle the P0128 disable in your tuning software.

How about a p0128 code when I have replaced thermostat and it is still there? Mishimoto intercooler and charge pipes/radiator hoses, HPS silicone hose kit, PRL CAI(race maf), PRL DP&FP, braided clutch cable. I'm also getting a p003a/p2563 and I can't get rid of them to save my life... Replace temp sensor maybe? For the p0128?

Sorry but I do not have much input to offer there, but I can say that if you have not installed a flex fuel kit you should not have to permanently disable the code.

You may want to check the connection on your ECT2 sensor. It's near the bottom of the radiator, perhaps it could have been bumped during some of your other installs.
