trouble code p0102 maf replaced code comes back need help Hey guys I have a 2001 camaro z28. A co.uple oflike two or three weeks ago the service engine soon light came on so I got the codes ran. I just replaced the mar sensor and ran down the road and went cut the car off and went in the store then I came out and the light comes back on. So I went back and had it ran the codes ran again and it came up with the same code. I'm so confused because I just replaced the mar sensor and bought it brand new.and the car dose seem to idle alittle rough and it will studded some I just don't know what to do please help. And yes I did erase the code after I put the new maf.

Check the ENG SEN fuse...is it blown? If so, it could be several issues. Try replacing the fuse and see if that takes care of it. If the fuse blows again, then you are in the same boat as I am. It seems that there are several possibilities at that point...could be bad 02 sensor(s), could be a short somewhere on the circuit. I am still trying to locate the problem myself.

ok so i replaced the maf with a new duralast maf and found the eng sen fuse the was blown and i replaced it. then this morning i cranked up the car and the code came back now i see theat yall are saying that the hose from the maf to the throttle body was broke i still have the original hose the came factory on the car should i try and replace this with a metal one from autozone like i see that a lit of people have done this to there cars but also was thinking that it might be the map sensor messing up and causing the maf to mess up and sending **** down the river causeing the o2 sensors to mess up a little bit but this seens like kinda a long strech

Before you do anything, very carefully check your pcv system for any vacuum leaks. You can chase a p0102 forever until you are absolutely sure you do not have a vacuum leak. The pcv system is notorious for leaking with age. Check all the rubber elbows and hoses. I completely removed mine, rebuilt it with other parts and the p0102 was gone forever.
