Abstract:
Methods and systems are provided for waking up a powertrain control module of an engine-driven vehicle during engine soak to perform an offset test of an exhaust NOx sensor. In one example, a method includes determining a duration to delay waking up the powertrain control module based on exhaust temperature at vehicle-off, waking up the powertrain control module after the duration has expired, and then initiating heating of the NOx sensor. After the NOx sensor lights off, heating continues for an additional duration before offset testing of the NOx sensor is performed.

Claim (Index 8):
A method, comprising:\n during a soak period following vehicle-off of an engine-driven vehicle, waking up a powertrain control module (PCM); heating an exhaust NOx sensor; at light-off of the NOx sensor, detecting NOx sensor output, determining a duration to continue heating the NOx sensor based on the detected output, and continuing to heat the NOx sensor until the duration ends; and performing a NOx sensor offset test at the end of the duration.
