When it comes to replacing this part, there are multiple things to take into consideration. When the ECM sends a signal, oil is directed from the PCV valve housing to control which camshaft lobe moves and controls how much timing changes. The oil control valve functions by controlling the oil flow to different engine components within the Variable Valve Timing system. In some cases, consumers have reported oil consumption related to this issue as well as misfires along with a rough idle. When this happens, it results in poor performance or engine stalling due to incorrect air/fuel ratios. This occurs when carbon deposits build up on the solenoid’s plunger and inside of the solenoid body near-vacuum ports causing a lack of response from activation. ![]() They typically fail because they cannot properly control airflow and fuel. The Variable Valve Timing Solenoid is an electronically controlled solenoid valve operated by the ECM. What is an Oil Control Valve (and How Does It Work?) We’ll discuss this further later in the article. The average cost of replacing this part is $325. Usually, the VVT solenoid will have to be replaced with a new one because it is not serviceable or repairable. When it fails, the most common symptoms include a “P0016” code, a rough idle, and an excessively loud valve ticking noise. It is controlled by an electrical solenoid that controls oil flow to a cam phaser which moves the camshaft to advance or retard the valve timing. The components include a cam sprocket, cam chain, crankshaft sprocket, and the Variable Valve Timing Solenoid (VVT). Learn how much it costs to replace a variable valve timing solenoid. It consists of many components that work together to adjust the timing of the valves. This system can alter the timing of the valves to allow for better performance and fuel economy. One of the most impressive systems created for combustion engines was the Variable Valve Timing System.
