my dodge has code p 0340. I changed the sensor but still pops up. I tried to check if I had signal but im not sure if I did it right. I also for continuity, not sure if I tested that right either. I did however start the truck and used paper clips to back probe the wires. I got one wire to read 5 volts and I tested the other and it read all over the place. I don't know if that means that wire is reading bad to the pcm.
I need help!
