Hi all,

Had a few posts about my cars problems and I seem to be getting to the bottom of it , I hope !!

Had it on a diagnostic and cleared the faults.

MAF was showing a low voltage signal and when I increased the revs the co2 readings did not alter. I had replaced the MAF with a cheap version off ebay. The car was running sweet then after a while it dropped into safe mode and emmissions light returned, I expected this.

My question is, looking at previous answers to other peoples problems, do I trust the MAF fault and assume the new unit is faulty or is there somthing else I need to be looking at electrically.

Fault codes

P0100 MAF/VAF sensor  Present -002 signal too low.

Would it be an idea to replace old sensor and reset faults and see what happens ?
