O2 Sensor - Which one is Bank 1, Sensor 2?
Pulled a code for the O2 sensor on my '98 5.9L Gas 2500. The printout says to replace the Bank 1, Sensor 2 one, which I assumed was the left side (driver's) after the Cat. Well, I crawl up underneath last night, and only find two sensors... one where the two downpipes come together before the Cat (sensor is in the center of the two's merge), and one after the Cat.
Just wanna double check before swapping out the $70 sensor, to make sure I'm changing out the right one. My Haynes says that the V10 and HD trucks have one sensor in each downpipe. Mine doesn't.
