Engine control module for use in vehicle system, has resistance measuring module determining resistance of heating element of oxygen sensor when heating element is heated to predetermined temperature

摘要

The module (30) has an exhaust heating module that operates an engine at a predetermined speed to generate an exhaust gas having a predetermined temperature, where the exhaust gas heats a heating element of an oxygen sensor. A temperature determination module determines, based on the predetermined speed, when the heating element is heated to the predetermined temperature, and a resistance measuring module determines a resistance of the heating element when the heating element is heated to the predetermined temperature. An independent claim is also included for an engine control method.
