After perusing our Forum and identifying most of the "quirks" and problem areas, I have either made the necessary repairs or taken preventive action to avoid unhappy surprises (which no doubt are out there in number just waiting...). I purchased replacement cam shaft and crankcase position sensors to keep as spares/back-up. I also downloaded and printed instructions for their repair. My question is this: Would it be a good idea to just go ahead and replace them now, in the comfort, safety and convenience of my garage? The car has 46k miles on the clock, and I just recently bought the car and cannot determine if the sensors are recently new. Are the replacement sensors bound to fail sooner or later anyway? If I can avoid surprise roadside repairs I would certainly like to. Opinions? Experiences? Advice? Thanks!

 

Carrying a spare RCM, in the trunk, is also recommend. The Relays wear out over time. They are plug and play and require no tools.

The cam position sensor is easy to replace because of it's location.
I replaced my crankshaft sensor at 48,000 miles in my garage before it went bad. I also keep another new one as a spare. I also wanted to have the experience of replacing it, in case I ever have to do it on the road.
Here's a link to the post I did when I replaced mine:

I'd recommend replacing the Crank Position Sensor simply due to it's age
