Hi All !! I checked my codes and found a 41 (after clearing everything). My question is "If my magnet fell off would it make noise and can i retrieve it ??" I'll replace the sensor no problemo !!! Any input is greatly appreciated !!! By the way its a 1992 se 8th vin code is L

It won't make any noise that I know of, but you will likely find it in there. There'* a few topics around if you search on Magnet. Most just glue it back in.

You can check to see if the interrupter magnet is missing by pulling the sensor and looking in the hole with a mirror and a flashlight as you turn the engine over by hand.

Padgett describes a glue in method here:
