Code P1DA9 Fiat Description

The transmission monitoring system uses three temperature sensors. If anyone of the sensors fails, the other two sensors are used for the control and temperature monitoring calculations and the Malfunction Indicator Lamp (MIL) will not be illuminated. The MIL will only illuminate when more than one temperature sensor has a failure.
