Aug 18, 2021· So in this instance, the sensor isn’t triggered by high temperature; rather, the sensor causes the high temperature to begin with. Sometimes this sensor can act up if they get contaminated with dirt and debris, in which case cleaning the sensor off may solve the problem. Otherwise, you’ll probably have to have the sensor replaced. Bad Water ...
Jul 28, 2003· DarkOne was nice enough to tell me that I probably have a bad coolant temp sensor, or a bad thermostat. Either my coolant is not getting hot enough for the ECU to switch into closed loop, or my coolant temp sensor is misreporting the temp and the same result happens. So my car is stuck in warm-up mode, and it will run nasty rich trying to warm ...
