Abstract:
A method of operating an engine control system includes generating an engine start signal, determining whether a cold start condition exists, energizing an electrically heated catalyst based on the cold start condition, determining the temperature of the electrically heated catalyst and selectively starting an engine based on the engine start signal and the electrically heated catalyst temperature.
