A few weeks back I had a P0118 code, coolant temp sensor.
The other morning about 1/2 mile from home I looked down and saw my coolant temp was pegged all the way red. Not possible. It usually takes 3-5 miles to get up to temps in the morning. Restarted car and it went back to normal. No code today.
What I'm trying to understand is where this temp sensor is actually located. I've heard people say it's in the t stat, and others say it's a different sensor on the engine back by cylinder 6.
Googling hasn't really given much info. Any help?
