Calibrating the D-180 OAT

[cdSIuOYEii]

I have tried to calibrate my OAT serveral times. It seems nothing happens I alway get a reading of 133 F and DA of 6420. Phoenix tends to be warm but not that hot. The probe is on the left wing behind the pitot. Can I get some assistance in where to look for the problem?

Probably a settings thing. If you have the OAT connected to the magnetometer, make sure that EFIS>SETUP>OAT is set to type 2, and that NONE of your GP inputs under EMS>SETUP>SENSORS is set to OAT. If you have it coming into the EMS 37 pin connector, the reverse is true. Set the EFIS side to N (for none), and make sure that the EMS GP input that is connected to the OAT is set to OAT.
