I recently decided to fix my airbag light and check engine light on my pickup. I haven't used this truck as an every day driver for quite a long time, and it has always run well when I needed it, so I didn't bother putting any money into the truck.
I guess I've had some free time and money on my hands to finally get it back into shape.
I had my codes read at Auto Zone and discovered I had a MAFS code and a Camshaft sensor code.
I purchased a used MAFS from eBay and a new Cam sensor and synchronizer combo from an auto parts store. I also purchased a new Air Bag module from the junkyard. I put the items into the vehicle, reset the computer via unplugging the battery and viola! the codes were gone. I love it when things go perfectly.
I drove the truck around for a couple days, to the junkyard for some aesthetic items to make the truck prettier, and to the upholstery man to redo the headliner. I wanted to make sure the codes wouldn't come back on me, which to my dismay they did.
I returned to Auto Zone, head hung low, and asked for another read. To my surprise it was a new code, which was P1443:
I replaced the gas cap in the summer of '09 along with some other small parts while I was putting new drums, rotors, shoes, and pads all around. So I'm going to assume it wouldn't be something as simple as the gas cap. It's possible the filler hose to the gas tank may have a crack or is loose, but I doubt it.
So I'm looking for some insight into my problem, and where I should be probing around to get to the bottom of this. I understand the selonoid/sensor connected to the vapor canister could cause this code, as well as the canister itself. It's possible the lines could be cracked and leaking too. I've visually inspected the lines, they seem to be okay, though old, probably original equipment. I don't know where the FTP sensor is, which I assume is the fuel tank pressure sensor. Is this located somewhere visible on the gas tank?
Any thoughts, inquiries, personal stories, or related information would be helpful.
I'd like to get this new problem fixed ASAP with as little money as possible. That free time and money on my hands is running out.
Thank you.
