silver03r50 Posted November 25, 2019 Share Posted November 25, 2019 got my self a very clapped out and rusty 2003 r50. all that's done to it is a set of general grabber AT 2. I've also been dealing with a lovely lean code on bank 2 so I'd love to hear some ideas about that I did hook up some scanners and senors and noticed that both of my post O2 sensors are malfunctioning. 2 Link to comment Share on other sites More sharing options...
RainGoat Posted November 25, 2019 Share Posted November 25, 2019 The O2 sensors are probably the most common failure on these trucks. Luckily, it’s a 15-30” fix. Unplug the old one up top, zip tie the new one to the old one’s line, drop the sensor from above, & once you’ve attached the new one below, clip off the ends of the old one. I’ve done it a handful of times. BTW, don’t forget Bank 1 is the passenger side on these trucks. Link to comment Share on other sites More sharing options...
