The sensors are primarily used for emissions control and ensuring the vehicle is running properly, Bickford explains. The two discuss the causes of sensor failures, such as wear and tear, environmental impacts and thermal shock.

The conversation touches on the differences between upstream and downstream sensors, the impact of mis-tuned engines on sensors, and the importance of following proper procedures and selecting the right sensors for specific applications. The episode concludes with information on where to find more resources and information on selecting the right products for vehicle applications.
