Trouble Codes

[jd08powerstroke]

I have had my truck in the shop 3 times in the last 3 weeks. Got it out today with new exhaust gaskets and a new exhaust back pressure sensor. I drove it about 30 miles today before it went into limp mode with four codes. Codes are as follows: P0069,P006B,P0106,P2262. I know what the codes mean, but I don't know a source for the problem. I have read a little about the MAP sensor, but it seems like many who have replaced it for one reason or the other only have a temporary fix. PLEASE HELP, I can't afford to send it to ford anymore just to come back and run for a little while. Please give suggestions on what this could be.

So im assuming its an 08 based on your name.

P2262-A code that i would start my diagnosing with. Screw the rest of the codes. If your VGT actuator is functioning when you go KOEO, if its not binding if you push it with your finger and let it return, go from there, LOOK for leaks, then check the rest of the codes. They all relate to turbo and boost performance. Sounds like your getting a beginner tech or one that doesnt know much about 6.4s
P006b- more than 1.5 psi difference between map and ebp sensor. Perhaps an exhaust leak or restriction in exhaust.
P0069- more than 1.5 psi difference between map and baro sensor-Perhaps you do have a biased map sensor
Before i condem ANY sensor. Especially a map sensor, i inspect the wiring harness while i have IDS hooked up i look at the pids for that sensor and wiggle the harness. Then i remove the map from the sensor and pump smoke through it with the smoke machine to find a leak, then put 30psi regulated shop air to it to verify a high pressure leak. Then i remove the hose and inspect that for any blockages.

Start there.
