What are possible problems if a 95 Millenia has lost power and will sometime shut down and you have pulled codes P1195 P1402 P1521 P1522?

Answer 1

There is a sensor up pn the firewall I think called an EGR sensor. I understand many Melinnias have this problem. Replacing the sensor for some reason just causes the replacement to go bad. My solution was to just remove it. Sure, my emissions are probably not as good, but it has never stalled again. My engine light stays on but hey, who cares? The sensor I found was located almost dead center - clightly to the driver side about 3-6 inches away from the firewall connected to an electrical connection. Mysterioiusly the part had a Mitsubishi emblem on it! Maybe an OEM part from the Mazda dealer would have corrected this, but my solution seems to work just fine.

I have the same 1st 2 codes(problem). The EGR valve assy is a spaceship shaped item, behind the rear spark plugs, slightly underneath the plugs. It has two vac hoses (top and bottom). The other part discussed above, is the MAP sensor. I found that one store may sell you the top portion of the MAP sensor assy, but not the lower. I have found that another store will sell you the whole assy, and all you have to do is remove 2 nuts, 2 vac hoses and 2 elec connectors. This I have done (whole assy). My codes are still there. This was the cheapest route, so far. That part was $200 at "AZ", with the EGR valve being $350. It may nickle and dime me, but at least it'll eventually pass local emissions testin requirements (eventually). I bought a scanner/eraser to check and erase my codes. Have not encountered the P15xx series, yet.
