Abstract
Various systems and methods are described for controlling an engine in a vehicle during engine operation, the engine having an exhaust and a NOsensor coupled in the engine exhaust, in response to an ambient temperature of the NOsensor. One example method comprises, during warm-up of the NOsensor and during cold engine starting, adjusting an engine operating condition in response to a NO-indicative reading of the NOsensor, the NO-indicative reading being compensated for ambient temperature effects on the NOsensor.
