I have this code that came up, it states that it is "MAP Barometric Pressure Correlation". What does that mean? The truck is a 2006 F350 FX4 with 52k miles, I have changed the fuel pressure spring, banjo spring upgrade, turbo back exhaust, and Volant intake, never been chipped or tuned, sits on new 35" toyos. if anyone has any ideas, i appreciate it, thanks, i am about to do an egr delete, before anything happens or leaks. thanks.

 

This is one of those codes that can be a few different things. But for starters I'd check the connectors on the sensor then I'd check for any vac leaks then I'd clear the code and see if it comes back but that's just me.

Just a thought how soon after you installed your intake did this code appear? I'm not sure about diesels but i had a Tacoma back in high school and when i put the intake on it threw a map code but it was because it was some pep boys China made filter I'm assuming because after I put a k&n on the code never came back. Idk if this applies though.

Is this the only code? Are there any problems at all with the truck that followed this code being thrown or previous problems that led up to it ?

 

map baro ebp and throttle pedal and egr i forget the other one, but are all tied into the same circuit. if thats just the only code, with the key off unplug the map sensor plug it back in and see if the code returns. if it does, pull the map sensor hose see if its leaking or plugged up with carbon. if it is just replace it. the code doesnt go away after that, get a new map sensor
