hi all, i have a 2000 eclipse gt and today my engine light came on with a code of P1400 manifold differential pressure system malfunction, I'm just wondering if anyone expirience this code and what can i do to fix it? Any help will be appreciated. I tried to reset it a couple of times just to check if its just an error but no luck, I really need it before getting sent overseas for military duty.

 

P1400 Heated Catalyst Battery Voltage or Current too Low During Heating (Bank 1)

 

thanks for the reply, any suggestion to fix it?

 

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.
