Unplugging bank 2 sensor
Hi all,
I recently bought a 2007 F150 Ext Cab Lariat 4x4 with the 5.4L 3v and i've been loving it so far! It needed a fair bit of work when i bought it (mostly brake work) and its almost all done.
It has something up with the cams (something i hear is a pretty common problem) and it spits out the following codes: P0340 and P0344. I believe both of those are because i have the cam sensor on one side unplugged. The only trouble is that when the sensor is plugged back in, the truck wont start. However, when the cam position sensor is unplugged, it runs like a champ.
The spark plugs were done about 40,000 KM ago (about 25,000 miles) so i dont think thats related to the issue. My local mechanic advised me to just leave it as is because it runs pretty good, but i also took it to my local ford, who thought it should be dealt with immediately. Both couldnt figure out the problem. (Ford suggested to remove the valve covers for further inspection, but i declined after they wanted $800 just to do the diagnostic) I was wondering if anyone might have any advice for me, i know cam issues are pretty common with the 5.4 3v. The truck has about 175,000 KM on it (a little more than 100,000 miles) Its also sounds like a diesel at idle, although i'm not too worried about that as the general consensus around here seems to be that its not something to worry about.
I was wondering if theres any downside to just leaving the sensor unplugged (other than it running a little rich) or if anyone might have any experience with fixing this issue.

Hello, I was just wondering what ever happened to your truck. I have an 04 and unplugged the bank 2 sensor today...seems to be running fine now. How long can I expect to drive my truck having unplugged the cam position sensor? Thank you!!
