Just as title says, Im getting a P00c7 code and after scanning the sensors, its my ambient Baro Sensor that is out (the one in the ECM). Is that just a redundant sensor to compare the engine sensors for testing or is it the sensor that drives the altitude tables also? I travel a lot and am wondering if just turning the codes off would keep everything operating ok or if Im stuck at one altitude (13.0) and am going to have to change the ECM to keep everything happy.
