Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me how the vehicle drives once it is started? How many miles are on it? Have you tried clearing the codes to see which ones return?>
Thank you. One more question. Is there any engine noise at all when you first start it?
Thank you. Typically when you get these codes all together it means that you have a worn out timing chain. Most of the time though this will also cause some engine noise. If there is no noise then the first thing I would do is change the camshaft and crankshaft sensors. If these are not reading correctly this will occur also and it is a much cheaper place to start than the timing chain. I hope this helps. Let me know if you need further assistance.,
