I have a 1997 saturn SL 1 with the 1.9 sohc. It has nearly 139000 miles on it and while it smokes and burns oil, it runs great. The problem I'm having is that I'm getting a code saying my coolant temperature guage has high output (po118). I replaced the coolant temperature guage but I still get the same code. I have reset it twice but it keeps coming back after running 5 minutes or so. What else could it be?

What exactly did you replace and where, the code is for ect sensor, engine coolant temp sensor located in the lower coolant passage in the cylinder head, is this what you replaced?

Yes, that's what I replaced. Today The dealer told me to replace the plug also, but I just have a feeling that isn't going to do the trick. Also, how do I vote and what is it for? I'm new to this site.
