What does a code p1400 mean on a Mitsubishi longer sport 200 mean

Here's a link to your code P1400. p1400 is your manifold differential sensor(MDP) and has nothing to do with your cat.

There is a small map sensor (MDP) that sits directly on top of your intake manifold. The sensor doesnt' seem to effect the car in any REAL way. I drove for 2 years with that code with no problems. I've just recently picked a used one from a guy who did a 6 bolt swap and the code is now gone. I didn't notice any difference by changing it though.

I think I paid 30 dollars shipped or something. New I believe they go for approximately 95 dollars US. Definately worth finding a used one if you can.
