1991 Oldsmobile 88 Q&A
1991 Oldsmobile 88 Question: Error 41 check engine light. Bad Cam sensor. What does magnet look like?
I removed the cam sensor and looked in hole where sensor was located. I wanted to see the magnet but all I saw was an empty square shaped hole. I assume that the magnet had been there but had fallen out. Does anyone know what I would see if everything was in it's proper place? - DonKent
Magnet is in the sensor itself! Other than code 41 any symptoms of a problem as this sensor may not be the trouble. Run rough, stalling, misfire ect.? - pushrod
go and buy one and you will see what it looks like then repl it near the crankshaft pulley. for pics ck out www.alldatadiy.com - globalhelper
"Google" 'hall effect' then you might understand better (making working on it easier).......although I just checked on 'wikipedia' and it's a little more technical than I was figuring! - ziptie12
