The Check Engine Light may erroneously illuminate, signifying a fault in the intake air temperature circuit. If no fault is found in the sensor or wiring, a simple reprogramming of the powertrain control module (PCM) may fix the problem.Google+

Kia Optima False Intake Air Temp Sensor Code Corrected With PCM Update
Kia Optima Problem

The check engine came on and when I took it to get the code read it came back P0110. The next day I took it in to my mechanic and the sensor and the circuit checked out fine. I am now in the process of trying to get into a dealer for the latest flash update for the PCM, so it hopefully, won't happen again.
