P2199 Intake Air Temperature Sensor 1/2 Correlation Low
The P2199 code means the two intake air temperature sensors are reading values too far apart when they should be close to each other, usually on a cold start. In most cases there is no symptom beyond the check engine light, so you can keep driving. The fix is to find which of the two sensors is off and replace it or repair its wiring.
