Code Po154, Po174
Hello all, I have my service engine soon light on now and took it to advanced auto to check if there are any codes and he came up with PO174 & PO154.
He tells me that it's the oxy sensor down stream... I have been doing some research on this matter and the net tells me that I have a Vacuum leak. Any help here would be great n tks for all your help here, Bob

Fix for the codes here
I just replaced a completely dead battery and wolaaa, No codes are given now and the truck runs great. I am just wondering about resetting the computer or anything besides the radio code that I had to put in...

UPDATE... Ok, Now I just ran some cataclean and some upper cylinder lube and reset the codes. Ran about half a tank out so far. Now the codes I get is P0174 Bank 2 system too lean, P0154 Oxygen circuit no activity detected bank 2 sensor 1 and P0401 exhaust gas recirculation flow insufficient detected.
Which one is bank 2 let alone number 1 ????

I just saw an ad on this page and clicked on it. Worth taking a look! It talks about electronic O2 sensor simulators and extension tubes.
