Abstract: Methods and systems are provided for assessing a state of a vent hose that fluidically couples a crankcase of an engine to an engine air intake system. In one example, a method may include sealing the crankcase from the vent hose, initiating cranking of the engine, monitoring a series of pressure pulsations during a monitoring window duration via a pressure sensor positioned between a crankcase oil separator and the vent hose, and indicating a presence of degradation associated with the vent hose based on the series of pressure pulsations and the monitoring window duration. In this way, diagnosis of a state of the vent hose may be reliably assessed without crankcase pressures confounding pressure measurements as recorded via the pressure sensor.

Abstract: Methods and systems are provided for learning fuel injector error for cylinder groups during a deceleration fuel shut-off (DFSO), where all cylinders of an engine are deactivated, sequentially firing each cylinder of a cylinder group, each cylinder fueled via consecutive first and second fuel pulses of differing fuel pulse width from an injector. Based on a lambda deviation between the first and second pulses, a fuel error for the injector and an air-fuel ratio imbalance for each cylinder is learned. Alternatively or additionally, a difference in crankshaft acceleration between the first and second pulses relative to the expected deviation may be used to learn torque error, and adjust fuel injector error and air-ratio imbalance for each cylinder.

In one example, a method may include in response to fueling of the engine of a hybrid electric vehicle being discontinued, establishing an air flow from an intake to an exhaust of the engine by relying on an electric motor to rotate the engine unfueled, and conducting a plurality of diagnostic monitors that rely on the air flow prior to reactivation of fueling of the engine. In this way, diagnostic monitor completion rates may be improved for hybrid electric vehicles, and fuel economy may be improved by coordinating the plurality of diagnostic monitors to be conducted during times when the engine is not fueled.
