If recently gone from about 19 mpg a couple months ago to 7 mpg. I have an edge CTS monitt that has been reading a cps sensor code, map sensor code, and exuast bake pressure code. I'm about to buy new ones as soon as a get paid. I believe that should help with the mpg, but I think I have a fuel leak also. There are no drips on the ground under neath the truck, but there if a lot of fluids on the left front wheel well. I've had this truck for just over 6 months, so I'm learning. Is there a fuel line above the left front wheel?

 

Yes this is were your supply and return lines for the engine run. They run on the top of the frame rail and are hard lines if I remember correctly and then have a short rubber hose that connects to the engine from the hard line. If you are seeing fuel here it would be the return line cause that is the only line under pressure cause the supply line is under vacuum cause the fuel pump is located on the engine

 

Thanks man, I'll get up under there and check it out as soon as it defrosts here. My wallet and I aren't liking this mileage at all.

 

If your not liking the mileage then unhook from that 5er. That's what I do! lol

 

by 5er do you mean the CTS? It's not a tuner, just a monitor. I wouldn't get the Edge programmer even if I could afford it.

 

Haha he meant his travel trailer.. He was being fascieous

 

Sorry Brad, Jarrett is right!


I never lie though, its true .

 

I wouldn't worry about the cps code. The back pressure code you could disconnect the ebpv and wire the valve open. And you could unplug the map sensor to see if there is a milage or power change
