I had a problem with code P1512 on a 2001 mazda mpv,it was a pending code according to my scaner, anyways all l did was drove it about 160 miles today, between hi-way and city miles and the code was erased by the pcm because l did not clear any codes l was just waiting for a complete driving cycle to pass emissions and as today only have 1 incomplete code so l guess by driving it lil bit more tommorrow should be ready once the P1512 is not in my pcm anymore.

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
