Installed the AEM Fuel Rail with the AEM FPR. Ever now and then I get a CEL CODE 3. I know what the code is, but what is causing it thx.

I think it has to do with my Fuel Pressure but not sure.

 

Code 3 is a MAP sensor code (you already knew that).

In your sig it states that you have a Drag turbo kit. You did not specify if you are running aftermarket engine management or check valves with OEM ECU.

As you already know, positive manifold pressure on a Honda/Acura with OEM engine management will cause a code 3 or code 5 (MAP sensor).

Give us more details so we can help you.

stock ecu with the V-AFC. No check valves.

 

Get those check valves in.. I would just with a Hondata 2b and GM 3 bar MAP... that should solve all your problems. Then you just gotta tune it.
