Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
A low oil pressure light on while running can mean the oil pressure sensor is bad or there is low pressure. Can you check the oil pressure?
There is not a CKP sensor warning light on the instrument cluster. Can you better explain what your seeing?
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
For the crankshaft I will need a trouble code on that. Can you check the engine oil pressure with a gauge in place of the pressure sensor?
