Thanks for asking your question. I will try and help you out.
164 indicates a fault with the injection actuation pressure system. This can be caused by several things. Could be a leaking injector, faulty IAP sensor, faulty injection pressure regulator, or weak high pressure pump.Please reply back if you need more help or have more questions. I am happy to assist.
