P0128 Code

rtcockrill · Post by **rtcockrill** » Fri Nov 15, 2019 12:58 pm

I have a 2014 Jeep Grand Cherokee SRT with a 180* TStat. I had a Jet brand installed for over 4 years with no codes thrown. I replaced it with a Mishimoto brand and now I get the P0128 code. I have adjusted my ECT down to 188 (180 TStat really opens at 185+3*), but I still get the code. Any ideas how to stop the code? Thank you for your help!

I also have a free flow catback with a CAI. I don't know if that makes any difference to the tune. Thanks

Ok. I loaded it onto my i3, now how to I load it on my truck? I selected 'select tune', but I didn't see it. What's it named?

did the device import the file?
put it in the root of the drive and let it import it then select it from the custom tune menu in the truck.
