Actual system coolant temps are in the 110-130 range when this happens...the indicated temp goes up rapidly to 226F simultaneously with the codes coming in. Indicated temp instantly goes back to a realistic value when you reset the codes. The only way the 226F could be true is if it was a localized pocket of hot water somehow, that clears when the thermostat goes closed. If the sensor is in the bypass line instead of the main flowstream, this could be true, I suppose, and all of this really is due to a sticking thermostat. But mKilgores experience would indicate that not to be the case(he reported he saw 400F indicated temps!?!)
BTW, I appreciate you weighing in...I know you have moved on from the 135 but your knowledge on the platform is acknowledged. Stoptechs and splitter you sold me are still going strong!
Keep poking holes in my ideas...helps me to clarify/correct my thoughts process.
