I see, thanks. If the Crankshaft Position (CKP) System Variation Learn Procedure cannot be completed successfully, refer to DTC P1336 CKP System Variation Not Learned for additional diagnostic information..If you accept my additional service request for your email address, you can give me your email in a private info box and I'll send you the test instructions for that in a PDF file, the file is rather large. You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it.
