P0053, now P0171 and P0174

[cashville]

I replaced them because on another thread, a guy told me that error (P0053) was the one he was getting, and he solved it by replacing the o2 sensors.

I will try what you said, and put the old one in bank2 and see if I only get the lean code on bank 1.

If that happens, I will put the old sensors back in, and should get the P0053 again. If that happens, what should I do to solve the o2 heater code?

Then i would buy a factory sensor, more money i know but should fix the problem. Check wiring to sensor and make sure its not rubbed through somewhere causing the problem

Thanks Humtech!

If it were wiring the old codes would have followed over to the new sensors as well. Whatever you do if you get lean codes that follow back to your old O2's dont ignore the fact that you "could " be lean because the 6.0's have common issues with vacuum leaks on the intake gasket.

So lets see..

I had error P0053 which indicates bad sensor/wiring in bank 1. The other day I got a blinking engine light when I was parking, so I just turned the engine off and on, and it went away, I left the truck in the parking space and only picked it up the next day with no problems. I think I should say this because it might help with something.
I figured it might have to do with the bad sensor, so I didn't make much of it (although now I now it means engine misfire, but I don't know if it could be related).

The 2 sensors arrived, and I switched them on both banks.

Right after switching them, and starting the engine, about 2 miles after I get the P0171 and P0174. I cleared the errors several times now, just to see if they come up frequently, and they do.
I never got those errors before, but I know they are common on the H2's. (Also I should point out, that I just got this H2, I only made about 150miles on it, but it came with the P0053 error already on, and not any others).

The thing is, if I never got an error on bank 2 before, and now I'm getting the P0174 which is a read from bank 2, could it be that the old sensor on bank 2 was completely dead (or disconnected) and didn't pick up anything, and these new sensors are good and are indeed correct on the vacuum leaks?

I just don't want to go ahead and purchase an oem sensor, wait 2 weeks for it to arrive, and see it didn't solve anything.
I don't know with what I should start on this matter...

Put your old sensors back on and get back to us with the results. It's too bad you cant datalog cause I could to tell you right away what your issue is.
