Ambient Temperature Reading stuck at 32 F on Odyssey
Posted: Wed Nov 11, 2020 12:42 am
Has anyone experienced a failure in the OAT ( outside ambient temperature ) system on an Odyssey EFIS G2 ? Mine is 12 years old (serial no. 62) and is finally starting service this month ( slow builder I know....). It only shows 32 on the EFIS display all of the time now. Originally it did display the ambient temperature correctly. At first I thought it was a bad sensor which I replaced, but it made no difference. Whether the sensor ( wired to plug pins 2 & 3) or no sensor, the reading stayed at 32. Checking voltages on main connector (pins 2 and 3 read) read approx. 5 volts with no sensor and 3 volts with sensor at room temperature. I heated up the new sensor some and it kept increasing in voltage as it warmed up. Any suggestions or advice appreciated. Thanks in advance. Russ
