Hey AcurazineI've been having some overheating problems with my car. I wasn't quite sure what it was so I took it in to Honda to get a full diagnosis. They checked all the hoses and the radiator. They told me they didn't find a engine code for overheating at all. He mentioned the MICU mechanism and said that could of been throwing my temperture gauge off. I have never heard of this MICU, is anyone else experiencing this problem and if so do you have any insight?

 

got a data scanner? it will tell you if the car is running hot. Are you bubbling coolant out? Mileage and year of car in question?

 

No to the scanner but it's about 120,000+miles on a 2004 TL

 

From what I can find, the Multiplex Integrated Control Unit (MICU) is built into the under-dash fuse/relay box.

 

check for any leaks under the hood..or even any signs of evaporating coolant that could floated around underneath the hood...
