Tge engine light has gone out I don't know if the fuel mileage will increase yet right now I'm at 4 MPG and I used to be sitting at 5.5 when I was put in this truck 2 years ago. Is there anything else I can do or clean that will only take a couple minutes as I am trying to do this without the owner being involved.

You cannot "clean" the IMAP sensor. Cleaning it might make it slightly better, but it cannot be properly cleaned. -- you need to replace it. All you cleand was the temp sensor part of it. the pressure sensor is up inside the head of it and solvents or digging at it makes it read wrong.

for $60 or so, just replace it!.

this is an indication that the rest of the intake and EGR circuits are just as bad. Do the whole thing. replace all the sensors, clean out allm the pipes, etc. while your at it. -- DPF PROBLEMS ARE ONLY A result of engine problems!. They are filters, and don't clog up without something clogging them up!.

Lower than normal fuel mileage is a sign of the engine making a lot of excess soot. oil pressure dropping off after a few thousand miles, then coming back when you change the oil is a sign of the engine making way too much excess soot. -- All of these problems can be solved, but if you don;t solve them, you will never get that DPF system to operate correctly.

THE ONLY WAY THESE EMISSIONS SYSTEMS WILL WORK IS WHEN THE ENGINE IS IN A VERY HEALTHY RUNNING STATE!.
