It's either the thermostat or the temp sensor.
I'm leaning towards the thermostat being partially opened all the time. I haven't really looked for it. Anybody know if it is buried somewhere only accessible by people with baby hands?
MD5 I live in Plano in DFW, who/where is your mechanic? Thanks in advanceAfter taking a good, hard look at the thermostat, I decided to pay someone to do it.
The new OEM Mazda t-stat was installed and the car has had multiple cycles and no CEL.
So, it cost me about $200 to get the t-stat replaced., but while they had the car, they tightend up the end links that were loose and clunking around. The mechanic also found that the rear passenger spring seat had come dislodged and was hanging down the inside of the spring. This was corrected as well.
