Abstract

Sensor apparatus includes a housing, a probe mounted to the housing, the probe including an elongate first part and a helical coil second part conductively coupled to each in series with first and second terminals at opposite ends thereof, the probe to be inserted into an exhaust stream in an exhaust corridor; and a circuit coupled to the first and second terminals of the sensor probe, to selectively operate the probe as a temperature sensor in a first mode and as a PM sensor in a second mode.
