Apologies if this question was already dealt with, but the site's search engine turned nothing up, so here goes. Am am consistently getting code 433 on my '94 850T. It has got something to do with the signal from the rear knock sensor, but I do not know how to check this. I have replaced all rubber elbows, so I am almost certain that it is not a vacuum leak. Just did the 120K service and everything service-related has been replaced, except the 02 sensors. Any thoughts on how what to check? Thanks
