Скачать или смотреть Master O2 Sensor Troubleshooting: Upstream vs. Downstream Made Simple

In this Tech Tip Short, Erik Screeden, technical and multimedia content director for Motor Age, dives into one of the most common yet confusing diagnostic issues — oxygen sensor troubleshooting. Many technicians face challenges when interpreting OBD-II codes, especially when it comes to identifying the correct O2 sensor bank location.

Screeden explains how to properly decode terms like bank 1 and bank 2, as well as the difference between upstream and downstream O2 sensors. Using the example of a P0157 diagnostic code, he shows how a downstream sensor on bank 2 might be misidentified if you don’t confirm where cylinder one is located. The video also highlights how catalytic converter efficiency monitoring plays a role in interpreting sensor signals. By following these steps, you can save time, avoid mistakes, and make the right replacement the first time. With Walker Products O2 sensors, you’ll get OE-quality performance every time. Watch the full short to learn more and sharpen your diagnostic skills.
