    P-0116, Check Engine.

    OK guys, new one for me.

    Today I was out riding and got a beep and check engine. Nothing else no funny running all normal. So went to shore to take a look, couldnt see anything strange.

    Started her back up, all normal up to 7500-8000 then it goes off again.

    Code is for engine temp function problem.

    Im running open loop with a thermo, I didnt get "Hi Temp" or "E Temp" come up, didnt seem hot at all just normal opperating temp.

    I just find it strange that it only goes off at high RPM, does the display show "Hi Temp" if it has got hot or does it just say check engine???

    04 RXP X charger, 42s, 4" air, gutted shorty thru hull. Open loop cooling.

    I have waterflow through the engine and the thermo seems to be working, flow increases and decreases as its opening and closing. Only odd thing is that she needs some pitch, the temps have really dropped and now its running into the limiter, im getting like 8000 at 80% throttle and straight to 8150 WOT.

    Bit lost, prob gona get another sensor to try might remove the thermo from the housing just to see if thats where the problem is. Maybe its not opening all the way so restricting at WOT and getting warm.

    Like I say tho it didnt seem hot, and i didntget any hi temp messages just check engine and P-0116.

    Thanks

    Do you think maybe one of your sensors is corroded and its not having a good ground due to running open loop, might want to check there, just a thought.

    Thanks, but the code is for the engine tempreture sensor, nothing to do with the exhaust.

    What I really need to know is, does the dash show "Hi Temp" or "E Temp" when they overheat??? I dont want to start chasing a cooling problem if I dont have one.

    I find it strange that it only happens at high rpm making me think its a tempreture problem, but it doest say anything on the dash about temp.

    Im going to try it with the thermo out and see if it happens, I got a temp gauge I can fit as well so ill stick that on and see what I got.

    The dash usually flashed the temp signal and says exhaust or temp sensor and check engine with the po116 code. At least in my experience. If you are running open loop, you might have a stuck thermo. The exhaust side is cooling fine so you are taking in enough water from the pump it seems. Let us know! Good luck bro!

    Try it without the thermo. Might have a flow or restriction issue in the thermo housing. It is not letting the proper amount of eater flow through my guess is.

    I agree, but what Im thinking is that would have caused it to get hot and therefore show "Hi Temp" or something, Im gona do just that tho, pull the thermo out and run without see what she does.

    Im sure its something dumbass, it was screaming before that, runs so so well but i need a little pitch.

    The thermo has been in there over a year now and when being stored its dry so corrosion could well be an issue.
