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.

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.
