At around 60000 miles right after my warranty was up my thermostat wen't out. It has been almost 2 yrs since the first time and it has now been replaced 7 times. From the time it is replaced it takes about 1-2 months and the check engine light comes on with the same code saying it is open. Each time we have checked the o ring and the o ring is bad. Thank goodness for part warranties otherwise I would be loosing over $100 each time. What is wrong with my car?!?!? Please help, I have no other issues, car runs fine.

 

what code is setting?
