Well, Some of you may have seen my 'doofus maximus'
post where I dropped a large amount of gasoline in my fuel tank.
I've got the truck running and we drove it while running some errands on Sunday (and I drove it to work yesterday). I'm getting a performance issue, and some fault codes and have questions. I hope you can all help.
I'm using a free software program and my all-in-one OBD-II interface to get this info.
P0401 - EGR flow insufficient
P0402 - EGR flow excessive
P0403 - EGR control
P0562 - system voltage low
P0683 - Glow plug module to pcm comm ckt
P0132B - I believe this is the new code that is caused by Ford eliminating the exhaust pressure sensor
P0132B* - same as above
I tried to clear the codes above and they did not go away. I suspect that the s/w I am using (scantool.net, V1.13) isn't set up correctly.
My question about the codes is: When one is trapped, how many start cycles does it take to clear it (if it is not caught again)?
I suspect 562, and 683 were due to me running down the batteries while pumping the gasoline out of the lines, (i also had pulled the glow plug fuse and relay).
I also suspect my EGR valve may be toast. I had pulled it a couple of months ago and cleaned it - maybe it's gone now? I've got 87k on the clock and it's never been replaced.
The performance problem is this: During partial acceleration, I get a hesitation. Also accompanying this is a rallte of sorts but it sounds muted and hollow like something inside a cavity is rattling. This is combined with turbo boost fluctuations. Maybe this is the 'proof' my EGR valve is toast. I drove the truck last night and topped it off (got 14.8 mpg on 160 miles or so). On my way home, I didn't experience this problem at all.
What s/w should I get for my PC (free or pay) to read codes, and clear them?
I am hesitant in dropping a lot of cash into a new EGR valve without some confidence indeed that's the issue.
