By default, I have found myself in charge of maintaining a company truck. 2006 6.0 PSD, F350, 4x4 flatbed. We finally got to 36,000 miles on it this year (yes really), and I checked with the garage that was doing the oil changes, and the oil changes were the only work ever done. So I had them do the 30,000 mile service, and that's where the fun started. I don't think we need a new mechanic, but it is possible. The truck has been back to them twice since the service, and the check engine light is on again.
The first check engine light was obvious enough, a turbo hose had split, truck was down on power.
The second check engine light was not so obvious, the mechanic said the turbo and MAP sensor were not in agreement on pressures, so they replaced the MAP sensor.
The current check engine light, I'm going to guess is the same thing.
I don't have the exact code, but I will have to get it out of the computer shortly. The mechanic says we can replace the turbo or ignore the check engine light. Neither of these is a good option. It doesn't need a new turbo-I towed a 14,000 pound trailer with it right after the MAP sensor was replaced (before the check engine light came on the third time), and the truck was not down on power, temps were normal.
I'm assuming that at some point with the check engine light on, the truck will go into "limp" mode and cut the power and richen the fuel? (Not that you would notice a decrease in mileage with this pig, but power would be missed).
Anybody have a good starting point to keeping this engine happy?
