Exhaust Gas Temperature Sensor 1/2 Correlation
Moderate severity
What it means
EGT sensors 1 and 3 on bank 2 disagree by more than the allowed tolerance — one is reading off, or there is a real temperature gradient that exceeds the calibrated map (e.g. from a leaking exhaust joint between the two locations).
