Abstract
A system includes: a motor control module and an engine control module, where, when a temperature of an oxygen sensor in an exhaust system of an engine is less than a predetermined temperature while the engine is off: the motor control module is configured to apply power to an electric motor based on a driver torque request and drive rotation of a crankshaft; the engine control module is configured to, while the motor control module is applying power to the electric motor based on the driver torque request, not fuel the engine and not apply power to the oxygen sensor until a predetermined mass of air has flowed into the engine; and once the predetermined mass of air has flowed into the engine, the engine control module is configured to (a) apply power to the oxygen sensor and heat the oxygen sensor and (b) selectively start fueling the engine.
