Egrt Temp Oddity?

[dsmfa9nutter]

In mmcd, my EGRT is at a constant -18.1*F. What can cause this and how would I fix it?

Usually a sensor showing a constant reading of a negative value is a sign that the sensor is bad.

That sensor isn't logged on dsms, everyone's is that way...maybe it's used on 3s's?

It's only used on California DSM's. On federal DSM's it's an available input most often used to log AFR or to connect a MAP sensor to log boost.
