Should I just replace the cam sensor with this error? Would it take all guess work out to do so?

Thanks!

The answer is NO... clear the code.. and drive it... often it never come back.. even if it do... so what ?/ if the car running fine without missing.. or any problem... I just avoid it..

I too have 1994 850 turbo the check engine light come and stay on year round first I replace many part but it still come back. later I learn the 1994 have a ECU problem.... computer prolem triger these code to come on for nothing .. often the only way to fix it it replace with a new ECU that cost $2000.. I am not about to do that

on my car we just place a piece black tape over the engine check ligt.. and let it be.. I check and listen how car run.. I what wrong.. by the way it drive

hope this help...
