Conditions for storing fault codes
If, according to information from the sensor, the air temperature is below -45°C for 0.2 s in two driving cycles, the ECU memorizes code P0112 and turns on the malfunction indicator lamp. This check is carried out after the engine has been running while driving for 4 minutes 10 seconds and then it has been idling for 30 seconds (without interruption of fuel supply when coasting). This code indicates that the air temperature value output by the sensor or the ECU after the engine warms up is below normal.
