I have codes for the MAP Sensor and P1524. I replaced the MAP sensor, which seemed to resolve it, but within a few days the codes were popping again. I have a lot of smoke coming from the exhaust pipe. Can someone comment on how best to approach this problem and/or if the two could be related?

Thanks!

 

what engine? and you should trace your vacuum lines, and look for a leak in the map sensor circuit.

 

Thanks for the reply keninn. I am clearly a virgin poster lol I have a 2001 Mazda Millenia S.

 

1524 is ic bypass circuit. i think you have a vacuum leak. check your lines/tees
