I have a Check Engine light coming on. I went to AutoZone and got the P0116 code. This is the second time I recieved this code. The first time was about a year ago, and I replaced the engine temp sensor ($50+ part!) and the light went off. I can't really see that part going out twice (isn't it just a simple therostat?). Does anybody have any cheaper suggestions? The wires are not damaged and are plugged in well. The thermostat? One thing to note is that it came on during the first really cold day we had this year. Any help would be very much appreciated!

I had the same error. Replaced the themostat and it went away.

Mine had the same code a while back. I too, installed a new sensor to no avail. Turns out, the darned thermostat was broken in two at the factory rivets holding the top & bottom pieces together. The center shaft holding the disc was bent roughly 10 degrees off center!

Go down the road and note the behavior of the temperature indicator. Replace the thermostat if the needle fluctuates with respect to engine load. In other words - ascending a long steep grade, does the needle climb? Likewise, going downhill, does it drop?? Heck, just replace the thing. Took 30 minutes at the most.
