so recently my GF came to me since her car would not rev past about 2500 and she smelled some burning in her 2003 maxima gxe

i pulled out the ecu and one of the control chips is burnt out.
from what ive found its either the iacv or the motor mounts that typically cause the ecu to fry and supposedly this third chip is the iacv control chip?

ive already go a replacment ecu on the way, i just need to verify that this is the iacv as im planning on unplugging the motor mounts anyways.

im also having a hell of a time finding a replacement iacv for a 2003 maxima specifically as everything that pops up always says for 2000-2001 or for a sentra. so if anyone knows where to find one.

 

got it figured out. the 2003 has the iacv built into the throttle body.

part number 1611k8j10bre same one you would get from the nissan dealer.
