What is the meaning of OBD-II p1345 code , and what are the possible causes and how to solve this issue?

OBD-II code P1345 is a generic code that indicates a problem with the Variable Valve Timing (VVT) or Variable Valve Lift (VVL) system in your vehicle. The code definition is "VVT or VVL System Malfunction (Bank 1)". The possible causes for this code to be triggered include: A faulty VVT or VVL actuator A problem with the oil control valve that operates the VVT or VVL system A worn or damaged camshaft or camshaft position sensor A damaged or corroded wiring or connector in the VVT or VVL system A malfunctioning PCM (Powertrain Control Module) or its programming Insufficient oil pressure to the VVT or VVL system To solve this issue, a mechanic would typically perform a visual inspection of the VVT or VVL system and its components, including the actuator, oil control valve, and wiring. They may also perform a scan of the vehicle's computer system to retrieve any stored codes and freeze frame data. Further diagnosis may be necessary, such as checking the oil pressure in the engine, testing the operation of the camshaft position sensor, or testing the control circuit for the VVT or VVL actuator. If a specific component is found to be faulty, such as a worn camshaft or a malfunctioning actuator, it will need to be replaced.
