Subject: Question about Temp Guage?
In my post I explained that it was stuck and it goes to normal temps after about 5 to 10 minutes or so. I took it for a drive tonight and after it finally went up to normal temps and stayed. On the way home it dropped to the bottom again and the service engine soon light came on. Do you think it may be the thermostat stuck open if it'* having these problems. Basically it stays at the bottom and then goes up to normal temps after awile then dropped back to the bottom. Also with my heat problem, I ran the codes on the climate controle and got a 140 and a 152. The 140 is the airmix actuatator. Could a stuck thermostat cause that from working? or is that going to have to be replaced?
This was a PM. Your ECT wiring is either shorting, or your temps are cycling like I've never seen. You need to explore both options. Disconnect your ect and check for a short between both wires while you wiggle the harness. Also change your thermostat. Good excuse to go with a 180.
Your Airmix code is unrelated to any ECT or thermostat problems. Ignore the 152 code. You can clear that after you fix the Airmix door.
Please try to keep all your troubleshooting in the open forum. I get 10-20 PM'* a day, and cannot respond to them all. If I had the time to solve problems through PM'*, nobody else would benefit from seeing you fix these problems. We need this information in the public eye.
