Systems and methods for waking a controller from a sleep mode are described. In one example, the controller may be woke in response to an estimated amount of time that it will take for a temperature in an evaporative emissions system to be within a threshold temperature of ambient temperature.

System and method for a vehicle diagnostic wakeup

Methods and systems are provided for a heat exchanger phase change material installed as a component of a variable exhaust tuning system. In one example, a method may include absorbing excess heat energy from exhaust gases during and after an engine-on event within a heat exchanger material, releasing heat energy stored in the heat exchanger material during and after an engine-off event, and heating an adjustable exhaust valve with the heat energy stored in the heat exchanger material.

Heat exchanger for exhaust tuning system

Methods and systems are provided for operating a vehicle that includes an exhaust gas heat recovery device having an exhaust heat recovery device valve that may be selectively opened and closed. In one example, a method may include storing heat from exhaust gases in a phase changing material and releasing the stored heat to surroundings of an exhaust heat recovery device valve to reduce a possibility of the exhaust heat recovery device valve sticking.

Exhaust gas heat recovery device system and method

Methods and systems are provided for scheduling an alarm wake up to self-wake a control module of a vehicle while the vehicle is off to perform requesting features, including diagnostic and non-diagnostic afterrun tasks. In one example, a method may include, during a shutdown event of the control module, querying a plurality of requesting features for alarm wake up times, receiving a plurality of alarm wake up times from the plurality of requesting features, selecting one alarm wake up time from the plurality of alarm wake up times received, and setting a timer for the selected alarm wake up time. When the timer elapses at the selected alarm wake up time, the control module is woken and a request to run is sent to each of the plurality of requesting features.

System and method for control module alarm wake

Methods and systems are provided for adjusting and troubleshooting an adjustable exhaust valve of a variable exhaust tuning system. In one example, a method may include comparing engine startup conditions to engine conditions of a last engine off event, adjusting a position of the adjustable exhaust valve, and providing a diagnostic summary to a vehicle operator based upon the results of the comparison and adjustment.

Method for variable position exhaust tuning valve diagnostics

Methods and systems are provided for on-board diagnostics of components of an exhaust gas heat recovery (EGHR) system including engine coolant temperature sensors coupled to the system. Degradation of one or more of a first coolant temperature sensor coupled upstream of a heat exchanger of the EGHR system and a second coolant temperature sensor coupled downstream of the heat exchanger may be indicated based on a difference between a modeled coolant temperature and a measured coolant temperature, the modeled coolant temperature based on one or more of heat transfer between a heater core and vehicle cabin, and heat transfer between exhaust flowing via the heat exchanger and coolant flowing through the heat exchanger.
