P1111 VOLVO Meaning
The engine control module (ECM) monitors the outside temperature sensor. If the control module receives a signal from the outside temperature sensor corresponding to a temperature below -39°C (-38.2°F) (low signal) or above +129°C (264.2°F) (high signal), the control module interprets this as a fault and the diagnostic trouble code (DTC) is stored.
