My T-25 died and got oil everywhere in the engine (intake pipe, I/C pipe, I/C, etc.), when I fired up the car after replacing the turbo, I got the P1400 CEL for Manufacturer Auxiliary Control Emissions. I know the MDP also has the same CEL, but I think this code could also be for the cat? Is this a multipurpose CEL? I've already replaced the MDP once!
