Hey fellas, please help me with the part# for the exact O2 Sensor that needs replacing when I get an error code reading P0138? I know there's a couple of different O2 sensors and I want to buy the right one to remedy the problem. I have a 2002 dodge ram 1500 Quad cab 8ft cargo bed 5.9 v8 4-Spd. Automatic 46RE transmission.
