2003 cadillac cts: crankshaft position sensor..gasket..valve covers

This answer was rated:

How much should it cost to replace crankshaft position sensor and is there 1 or 2 in the car? Also, how much should it cost to replace gasket valve covers both of them. I want to have an idea since these need to be fixed on my car! 2003 cadillac cts sports/luxury version.
Welcome. THE sensors are about 100 each and about 100 to change them so about 300, and the valve cover gaskets are likely about 30-50 each an a few hours to do these. I suspect all these would run you about 600-700 at a guess.

How many cranksalf position sensors are there in the cadillac?

There are 2 and they are one above the other. THey are also VERY COMMON for causing issues.

Yep im having the SAME ISSUE now. haha. so if one goes out is it likely the other is going as well? do both usually need replacing. I just want to have an idea of whats going on so i dont get ripped off :(


thanks Nicole.

Anyone who does not replace them as a pair is not doing the job correctly then. Like salt and pepper, they go together.

ok, well my mechanic just called back and said its not the valve cover gaskets, all i need to replace is the crankshalf sensors all will do the work for $220, earlier he said there was oil leaking, can the crankshalf sensors cause an oil leak?
The crank sensors do go into the oil and they can leak. 220 is a good price provided those are true GM sensors and not aftermarket.
