Detroit TRS sensor

I made a post a month or so ago about a gremlin that I cannot find, nor has anyone (including a Freightliner service manager) been able to shed any light on what it could be. This is a continuation of me throwing parts at it hoping to find something, as all other logical ideas have already been exhausted. Well, I have a question about the TRS (crank) sensor on a 2006 Detroit 14L. I have found many posts where these sensors have caused an engine not to start... However, I was wondering if these sensors can actually give problems before they go completely bad? To me, I would think the sensor works fine, or it don't work at all.. Has anyone ever seen these sensors give intermittent problems while on their way to going completely bad?? I replaced mine today after working 4 hours just trying to remove it!! There was no metal on the tip and nothing has ever touched down on it.. I haven't got a chance to test drive it to see if it changed anything, but I'm thinking I may have wasted my time doing this! What have you seen regarding these sensors?

 

I have replaced all the wiring harnesses with new ones. Just wondering if the sensor itself can cause intermittent problems.

 

Yes it's clean and dry, but I'm glad to hear somebody has experienced intermittent problems out of this sensor. Should be able to drive the truck today to see if it may have cured the miss.
