05 Dodge Ram 1500 5.7L Wondering Where Too Start?

[Dabneyskeys]

Fixing up my ram that's been sitting, starts, runs and drives great but I have not been driving it because of the Engine Trouble codes it has and I am just getting time to look at it.

I am currently getting codes,
- P0174 - system to lean bank 2
- P0151 - 02 sensor circuit low voltage bank 2 sensor 1
- P0404 - Exhaust Gas Recirculation control circuit range/performance
- P0700 - Transmission Control System (MIL Request)

Before it set i was only getting the P0174 code.
I had the cat's replaced previously and I replaced up and down stream 02 sensors when I got the 02 code but the code came back.

I was looking for advice on where to start

Check the wiring to the cats. Make sure the wires are not broken or melted. Sometimes the wiring can get melted on the exhaust.

The wiring from all 4, 02 sensors look new still. And I don’t see any damage from the plug to the harness either.

Also I inspected the exhaust and there are no contact points with any wiring, everything is tucked out of the way.

I am currently getting codes,
- P0174 - system to lean bank 2
- P0151 - 02 sensor circuit low voltage bank 2 sensor 1
- P0404 - Exhaust Gas Recirculation control circuit range/performance

To me this looks like a bad EGR valve/gaskets and bad oxygen sensors. I'd replace them all, if the wiring and connectors all look good.

Did you use mopar 02 sensors ? Aftermarket doesn’t always play well with our trucks .
