Abstract
An exhaust guide guides exhaust gases within an exhaust system to an intake portion of a sensor when an input port and an output port of the exhaust guide are positioned within an exhaust gas flow. A high pressure region formed at the input port and a low pressure region formed at the output port facilitate the flow of the gases through a chamber housing that at least houses the intake portion of the sensor. Contamination of the sampled gases by outside air is minimized. In some configurations, the sensor is mounted outside of the exhaust system to increase the thermal isolation between the sensor and the exhaust system improving the performance and increasing the useful life of the sensor.
