EGR Pintle stuck closed
Hi Kristy,here's a link to your P0400 code.
SOURCE: power window issues
Try removing the fuse to the windows and see if that resets the system. I know what your talking about of the 02 Altima, have a issue with mine using to much oil and the dealership says there nothing wrong.
Hope this helps with the window issue

SOURCE: whate is code 1400 and 400 in nissan altima 2001.
P1400 DPFE Circuit Low Input
P0400 Exhaust Gas Recirculation Flow Malfunction
These codes represent a fault in the Auxiliary
Emission Controls. Here's a brief describing of the EGR valve. The EGR stands for exhaust gas recycling valve.
During cruising speeds, the valve opens allowing exhaust into the intake manifold.
The purpose of this is to cool the temperature of the combustion inside the cylinder
as the spark plug fires. This in turn, lowers emissions. If the EGR is stuck in either direction(open/closed), it can effect the idle of your vehicle and can stall it out at times. it can also trip the engine light as well. Good rule of thumb is to clean out the carbon out of the intake manifold thoroughly before you install a new EGR. this will prevent the engine light form coming on once more. if the carbon build up is high, chunks of it will jam the EGR, causing it to fail over and over.
Please rate and god bless.
SOURCE: What does trouble code 12 mean on nissan altima
a code 12 means no G or Ne signal to the ecu im put side for at least 2 seconds that code is ground (G) so it is an open or short to ground on the ECU threw the STA circuit
SOURCE: The alarm on my 08 Nissan Altima keeps going off.
YOU WILL REQUIRE DIAGNOSTIC TO DO THIS BUT IF YOUR VEHICLE IS LOCK IN A SAFE AREA JUST LEAVE ONE COMPONENT OPEN AND CHECK IF THE ALARM WILL SOUND AGAIN REPEAT THIS TILL YOU FIND THE DEFECTIVE COMPONENT.
