ABSTRACT:
A method and system for indirectly estimating ambient air temperature. The ambient air temperature is estimated based on filtering a temperature input from a turbocharger air inlet sensor. The filtering includes compensating for engine compartment temperature variations which vary relative to the actual ambient temperature.
