P0110: the intake air temperature sensor circuit has a fault
The intake air temperature sensor tells the engine control unit how warm the air entering the engine is, since colder air is denser and needs a slightly different amount of fuel. This code means the electrical circuit for that sensor isn't behaving the way the computer expects. It covers the wiring and connector as much as the sensor itself.

What the code itself says
P0110 is a powertrain (engine, gearbox and drive system) code, and the 0 after the letter means it is a generic code with a standard meaning.
Grouped here as: Engine running, fuelling and misfires — Air metering, fuelling, ignition, misfire, idle, boost, knock, oxygen sensors and the catalyst, all working together in the running engine. That grouping is ours, to help explain the code. The code's official family is the letter at the start.
This page is generic. Your car isn't.
A code on its own only tells you what the sensor saw, not what's actually wrong — and that changes next to your other codes. Read this one together with the rest of your scan and we'll work out what's really going on.
