What does this fault code mean?

At engine start the ECM stores the intake, fuel and engine temperature sensor values and compares them. The code is stored when the air temperature sensor signal corresponds to a temperature that is too far below 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, read the intake, fuel, outside and engine temperatures in live data at engine start; the intake value should match the surrounding air
3Check that the connectors at the air temperature sensor are free from contact resistance, play and oxidation
4If the value is not reasonable, the fault is present; if it is reasonable, the fault may have been temporary
5If the fault remains, have a workshop check the air temperature 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 control module uses the value from the outside air temperature sensor

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