Abstract:
Methods and systems are provided for accurately estimating intake aircharge based on the output of an intake oxygen sensor while flowing EGR, purge, or PCV hydrocarbons to the engine. The unadjusted aircharge estimate is used for engine fuel control while the hydrocarbon adjusted aircharge estimate is used for engine torque control. A controller is configured to sample the oxygen sensor at even increments in a time domain, stamp the sampled data in a crank angle domain, store the sampled data in a buffer, and then select one or more data samples corresponding to a last firing period from the buffer for estimating the intake aircharge.

Claim (Index 10):
The method of  claim 8 , wherein the output of the intake oxygen sensor includes a pumping current output upon application of a reference voltage to the sensor, the reference voltage including a voltage where water molecules do no dissociate at the sensor, the engine actuator adjusted including one or more of an intake throttle coupled to the intake passage and an EGR valve coupled to an EGR passage.
