Your MAF sensor is located on the intake body by your filter. Whats likely happening is its intermittently working and causing a lean condition in your motors. What then happens is your not getting enough combustion to adequately work your valve train so it rattles, clicks etc think of it as constantly bogging down. I had NO CEL for mine. However when I voltage tested it on a whim it failed. $50 bucks later my valve/ rocker arm tick was long gone and has since never returned. I have 168k miles on my motor and just drove across the country over the rockies , desert etc. no problems no noises. Motor now drives like a champ....also I highly recommend cleaning out your intake manifolds etc. mine was FILTHY. Seafoam worked wonders.

Reason: I'm a dumb ass and was working on my s2000 when I wrote that...it has a MAP.
