Coolant Temperature Sensor Issue

Hi All,

Just had a pure stage 2 turbo put in and after picking up I see the coolant temp is stuck on 405 degrees Fahrenheit and it seems to be acting like when it throws an engine malfunction but I'm not getting a code. Turned off the jb4 and still no codes.

Sensor? Where would it be located?

Fairly certain it's the sensor at this point. Can anyone help me out in pointing out where that sensor is located so I can take a look?

Also pulled codes and found this which is further proof that it is a sensor issue to me.

Sorry to hear about the sensor issue but congrats on the turbo upgrade! Can't wait to hear your initial impressions!

It's pretty much in limp mode now so no boost essentially but even with that if feels less torquey but if you look at the speedometer holy hell is it fast! I'm dying to fix it and see what it's like!

Figured it out, somehow the plug wasn't well seated. Plugged in and all good now.

I was going to say it's usually something simple.
