I have a 2005 Aveo LS, and the Camshaft Position Sensors went out and tripped a code, and now I think there's a leak of some sort. Can CPS going out cause this? I think it's an oil leak, which I thought could have been caused by something having to do with the camshaft or the the timing belt. Like maybe caused from a crank shaft seal under the timing cover.. I hope its not anything more serious.
