p1400 code
 

I have a Diamante 2001 that had a P1400 check engine code. I replaced the manifold differential pressior sensor or mdp sensor part # MD305600 and that took care of the problem. Advance Auto wanted $167 for it I got it from LKQ for $5. Pull-a-part may have some cars that may have it also because this part is used in many Mitsubishi modules.
