Re: FYI PO178 & PO179 Codes
Yes, those are the flex fuel codes. If your truck throws those codes, your sensor has failed and needs to be replaced. I have those codes up on my truck right now but I don’t have the funds to get the sensor yet. My gas mileage has turned to crap because this sensor is feeding the wrong data back to the computer for fuel management.
You are correct where it is located and that you have to go to GM to get the part.
That was a good idea to see if you can find one in the wrecking yard if you can get it for $20 to $30 bucks. If it works, that’s a cheep fix. If not, then you’re not out a lot of cash.
