Method and apparatus to evaluate an intake air temperature monitoring circuit

An electronic controller operable to monitor an intake air temperature sensing circuit for an internal combustion engine, comprising:

• the electronic controller signally connected to the intake air temperature sensing circuit, and, signally connected to a coolant temperature sensing circuit;
• the electronic controller signally connected to a plurality of engine sensors, each of the plurality of engine sensors operable to measure at least one engine operating condition;
• wherein the electronic controller is operable to:
• determine the measured intake air temperature changes in response to a change in actual intake air temperature, based upon the at least one engine operating condition and the measured intake air temperature;
• and,
• determine the measured intake air temperature is representative of actual intake air temperature, based upon the measured intake air temperature, the coolant temperature, and the at least one engine operating condition.
