Accuracy in cell testing can be affected by temperature, thus the need for temp-measurement sensors. And the positioning of that sensor is a sometimes overlooked, but essential, factor. When testing ...

If it's still not heating correctly, you can use an ohmmeter to test that the sensor is working. The resistance of the sensor should rise with the internal temperature of the oven.

In the present investigation, temperature sensitivity of the oxygen sensor was measured over a wide range of engine operating conditions. Sensor data were plotted in the form of contour lines of ...
