Method for Testing a NOx Sensor

A method for testing a sensor positioned downstream of an engine. The method includes motoring the engine, receiving a signal indicative of a value from the sensor, and determining whether the value is inside or outside of an established range. The established range is based on a known characteristi...

Zusammenfassung:	A method for testing a sensor positioned downstream of an engine. The method includes motoring the engine, receiving a signal indicative of a value from the sensor, and determining whether the value is inside or outside of an established range. The established range is based on a known characteristic of an exhaust gas exiting from the engine as it is motoring.
