P0110 to P0114: intake air temperature sensor
The sensor that measures the temperature of the air coming into the engine has a circuit fault or an implausible reading. P0113 (signal high) is the one seen most.
SeverityLowLittle risk to the car, but the fault stays until it is repaired.

The intake air temperature sensor lets the computer correct the fuel and ignition for air density: cold air is denser than hot air. It is usually a simple thermistor, often built into the air flow sensor. A signal stuck high normally means the circuit is open, which the computer reads as extremely cold air; stuck low means a short.
What causes P0113?
- A sensor left unplugged after an air filter change
- A broken wire or a corroded terminal
- A failed sensor, or a failed air flow sensor where it is built in
- A cracked connector housing that lets water in
What to check first for P0113
- Make sure the sensor or air flow sensor is plugged in fully
- Compare the reading on a scan tool with the outside temperature on a cold engine
- Check the terminals for corrosion and the wires for breaks
- Measure the sensor's resistance against the specification for its temperature
Can you drive with P0113?
Safe to drive. The engine may run slightly rich or hesitate in cold weather, and economy can drop, so have it fixed when convenient.
Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.
