I have a 2008 Acura RL that has a code p2185. Says coolant temp sensor 2 high voltage. My problem is I can’t find coolant temp sensor 2. I thought it was located in the radiator but it’s not there and I know it’s not the One by the thermostat because that’s coolant temp sensor 1. My code is for sensor 2 which I cannot find. Any help would be awesome. Thank you

 

In my 2010, the sensor is at the bottom of radiator on driver's side. It's probably on same location on 2006, make sure to drain coolant before removing it lol.

 

Well that’s the problem. I thought it was in the bottom of the radiator but it’s not there. I even took the fans out to get a better look and nothing
