I washed my car this morning and afterward, the OAT registered 71 degrees on both the I-panel as well as on the PCM. An hour or so later, the correct temp displayed, so the obvious root cause is that I got water on the sensor leads. I'd like to avoid that in the future. Does anyone here know where the OAT sensor is located, so I can make certain it's insulated as it should be?

Thanks!

 

OAT = outside air temp...? if so, then it's right hand side below the fog light in the air vent, sticking thru the radiator ducting.

 

Yup. OAT = outside air temp.

Thanks for the info. I'll look and see.
