Looking for help on resolving an issue that has plagued my 2008 Dodge Ram 1500. The dealer still has not been able to correct issue. Issue is as follows. I am looking for cause and possible solutions.

I know what the codes mean. The codes are P0135. P0141, P0032, P0038, P0052, P0058. I have replaced all 4 Oxygen Sensors this last time with MOPAR OEM from the Dealer and had the IPCM re-flashed by the dealer. Nothing has worked to include their diagnostics 4 times. Also know that when I did the scan again and cleared the codes it only takes about 1 minute for all the codes to return and codes P0141, P0032, and P0052 show up twice on the scan

Given the fact that the sensors have been replaced with a PCM flash done as well, and the immediate return of the codes when you fire it up, my though here is that you have frayed wiring and/or a failed connector in the harness, i.e., a short.

I've had each sensor's wiring connector and circuit tested for continuity, then from each harness connector upstream to the main harness tested as well.

Not looking up the codes, what are the actual codes? And flashing the PCM doesn't mean it's going to fix it. And internal failure is an internal failure. Flash or not, it won't be fixed if it's not right inside
