What does this fault code mean?

At engine start the ECM stores the intake, fuel and engine temperature values and compares them with the air temperature sensor reading. The code is stored when that reading corresponds to a temperature that exceeds a set limit compared with the others.

Possible causes

Damaged air temperature sensor
Contact resistance or oxidation in the air temperature sensor connections

What you can do

1Read and note the code, clear it and road test to see whether it returns
2If you have diagnostic equipment, compare the intake and outside temperature values in live data straight after a cold start; they should be close together
3Check the air temperature sensor connector for loose contact, contact resistance and oxidation
4If the reading is unreasonable, the fault is present; otherwise it may have been temporary
5If the fault remains, have a workshop check the sensor

Symptoms you may notice3

The eco indicator lamp in the instrument panel lights up
The engine is hard to start
The car has reduced performance

What the fault can affect1

The intake air temperature is replaced with the value from the outside air temperature sensor

General guidance for car owners. Diagnosis on the car can point to a different cause.
