Question about 2001 Mazda MPV
After extensive searching and trial and error I found that the cause for the code 1518 on my mazda mpv was caused by the plastic clip that holds the linkage for the intake manifold runner had broke on the fire wall side and the linkage fell out causing the runner to stay open. It is very difficult to see. It is on the front( drivers side) of the engine below the upper intake manifold. Remove the air cleaner box and use a mirror and you can see it. Only about 6 inches long. Replace both clips while you are in there because it is a bear to get to. Check this first before you go through the other items like the egr. Inexpensive repair and my code 1518 and the one for randon miss fire went away never to return. Lots of power again. Good luck. Jim

I had the same problem and it happened at high speed on an Interstate Mountain (Hwy 5 from Kelowna to Meritt).... so scared but car ran fine all the way.... so hope it goes away.... I had the check engine light removed and hope it does not reappear

P0031 - most likely pointing to a failed O2 sensor (bank 1 sensor 1 is located before the catalytic converter)
P0421 - failed catalytic converter or a failed O2 sensor
P1512 - intake manifold shutter valve is stuck - may be caused by the O2 sensor, but may not
I recommend replacing your O2 sensor first and see what happens
