Jim Warman Posted April 1, 2008 Share Posted April 1, 2008 Well.... I promised a post for a very interesting truck.... After a lot of hunt and peck typing, I got "page unavailable" and all my "work" got lost - possibly in the "lost sock" dimension.... Since it's late, I'm sad to say that this will have to take it's place until tomorrow night... I may have more info by then.... Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted April 3, 2008 Author Share Posted April 3, 2008 OK.. let's give this another bash and see if the electron Gods will smile on me. Victim is an 06 F350... On Demand code P0113 and, in memory, P0402, P1102 and P2199. Of course this is a truck that is on it's way to a job, good customer and we are squeezing it in as a favour.... with nowhere near enough time allotted for what it deserves. Right away, we can see the search for a magic bullet. The P0113 turned out to be a simple broken wire at the MAF connector. Fixed that and verified the repair, then ran KOER... Retrieving P1102 and P1408 every time. It passes the EGR test. Popped out the EGR valve... quite a bit of fluffy carbon, but the valve moves smoothly. Manipulating the valve in datalogger, we see the valve open nicely... at 100% DC, the motor has only gotten marginally quieter and IAT2 hasn't changed.... OK, we're probably looking at a plugged EGR cooler.... At first I thought the P1102 might have to be reassessed after the EGR repair... But a plugged EGR system should increase the MAF numbers, right? I might possibly have missed something when I inspected C-128 and no time for me to think of checking for a wire chaffe at the left spring tower.... Ah, well... tomorrows another day....
