Hello and good day. I have some issue with my 07 gxp, been trifecta tune for little over a year now with almost zero issues until now (im not sure its the tune although). The first problem is this code that came up when my check engine light came on.

P0119 Dev:05E8 History SES Stored
Engine Coolant Temperature Circuit Intermittent

what does this mean? I use the ezflash software to scan the code with the tractrix box openport 2.0



The second problem is the car just lose power out of no where, down to 4 psi and stays there until i restart car, and you can feel when the 4 psi kicks in because the car jerks while driving then BAM no power. I tried re-flashing car that didn't work, had to replace MAP sensor that seem to help the check like the first time, but now i have the new code above when engine light came on.


Any Infomation would be Great Thanks.....

OBD II Code P0119

that should help out some

Wow thanks a lot. This must be the reason for the lost of power when the car engine gets hot while I'm driving (Hench the 4 psi) so either I have to clean the lines or replace the sensor.

Quick question, would you happen to know where the sensor is located or have a picture of the location and part as well?

Yes that's the right sensor and I found this picture that may be good use, it's for the 2.4L solstice, may be the same in the gxp



Looks like it's underneath the turbo/exhaust manifold, try taking it out and cleaning as it could solve the problem or do as I usually do and buy a new one just in case. Seems pretty easy to clean and change out

Wow your like my angel lol. I also looked on gmpartsdirect they it for 16$. fairly pretty cheap part, And thank for the picture but im kinda confused is that the front or back of engine? rather the hot or cold side? looks like a son of a *beep* to get too.


oops didnt see the bottom of your post sorry bout that.

I just did a little research and found some good info for you! That picture is the passenger side.

It does look pretty hard to get too, I have the 2.4L N/A and it was really easy to remove my headers and high flow catalytic converter. Now for you, you would have to remove the turbo, manifold and downpipe. It may be pretty easy once you start loosening nuts and bolts.

And here's an actual picture of the engine:

OH my lord. Welp guess I have to put the car up for the winter. Its snowing pretty bad out here so there's no way for me to even trying and replace this part. Ill try and drain the coolant and replace it with some fresh coolant, if that don't work then I tried lol. Because I'm no mechanic so I wouldn't even know where to start.


But I guess take of the manifold and Turbo should be too hard since I took the intake off before. Lmao.

lol, dealing with this, I would most likely let a mechanic take a look, but it could be pricey too

Just got this code, cleared it and it came back. Did the OP ever get this fixed with the sensor? Looking at the engine but i don't actually see where the sensor is.

So I replaced my t-stat, my coolant temp sensor, replaced my fan control module and still getting this code...
My guess is that you have a problem in the wiring to the sensor.... Dumb question here...how old is your battery? Sometimes a weak battery starts to play havoc with the sensors on this car for some reason.

So here is why the P0119 code is set:

The ECM detects that the ECT is intermittent or has abruptly changed for greater than 4 seconds

So, you might have gotten a bad "new" sensor. But, like I said, how old is your battery?

There isn't much in the shop manual other then to test the sensor and how to do it with resistors. My advice is to take the sensor back and tell them it's bad if your sure your battery is not bad. The other thing might be that the sensor was packaged wrong. But as far as testing procedures go in the shop manual, they give nothing else other then to test the sensor. I would put a charger on your battery and see if it is down at all. And let's face it....there have been many posts of people getting bad batteries and bad sensors here on the forums.... IF that isn't it, I don't know what else to tell you other then to start testing the wiring to the sensor. Maybe someone else can chime in.....Tomato??? Rob????

Did you ever get this code P0119 fixed? If so, do you remember what it was?

The reason I'm asking is, I getting that code too. Just purchased this car about a 1 1/2 months ago and it didn't have any codes being thrown then I flashed it with my tune from my other Solstice (same year, same options) and now I'm getting a P0119 code.

This code wasn't thrown until I put in the tune. It doesn't seem likely that it is a bad sensor or other component issue, it seems to be related to the tune. I guess I could put in the stock tune and see if it gives any codes. Maybe if I find time today I'll do that and let you know.
