Crank or cam position sensor

I like to keep some parts in stock for my cars. I'm considering buying a crank and/or a cam position sensor to just have on hand. They are each only about $35, so it's not like it's a bank buster. I've got an '03 SLK320. Is one of those sensors more likely to fail than the other and is it a reasonable idea to keep one or both on hand just in case? The car is not a daily driver, so even if it is out of commission for several days, that's not a big deal for me. I guess another option is to buy both and replace both and keep the old ones on hand just in case.

Your thoughts appreciated.

Hmmmm?, unless they are hard to get, just wait until it ends one.

Yeah, that's certainly an option and with the way I use the car, it's probably the best way to go.

Thanks for your reply.

Hi I have a 320 and had the crankshaft position sensor fail, gives plenty of warning and starts as an intermittent starting failure after the car had been driven then a slow speed engine stall, that's when I replaced mine, I bought an OBD reader just to check and confirm which sensor had failed, can't abvise on the crankshaft sensor as I have not had any problems with one.

Regards Stuart.

Thanks for the reply Stuart. Can you clarify something for me please? You mentioned crankshaft position sensor in both references. You must have meant camshaft position sensor for one of those. Is the cam sensor the one you did not have an issue with yet?

Good to know that you do get some warning. I do have a code reader, so I'm all set there.

Yes I meant camshaft sensor that I have not had a problem with, sausage fingers on small keypad.
