Re: P0017 & P0018 Crankshaft Position (CKP) Code - Timing Chain Stretched
Mine was throwing a CODE P0021 back in June of 2010 and they replaced the timing chain at that time.
In August, just my luck, they had to tear the engine down again and replaced the LH head and LH cam actuator. Without looking up the paperwork I cannot tell you what the codes that were being thrown the second time but probably the same as yours or heck could have just thrown another P0021 again.
