CTS high

#1 · May 26, 2019, 3:59 pm

Keep getting the error code cts high. The screen shows 185 degrees and doesnt budge. I can wiggle the harness at the plug and It will read temp changes for a little bit but will eventually go to 185 and stay. Do I need another new cts sensor?

That would be the first thing I would do. Get a Delco. Part number is on the Parts and Accessories topic.

Ok. I am also going to check down the harness and make sure there isn't an issue there either.

I replaced the sensor and ended up with the same fault. I put a mechanical gauge on and it reads fine. Something wrong with my fitech system. I'll have to call them in the morning

Hello @falkenstien - did you ever get this resolved? I am having this same issue with a build also and just wondering if you had a solution on this yet. Thanks for your time.
