The first one is checking engine light comes on. It’s important that you inspect the solenoid carefully for any debris that may be lingering about. Sometimes, debris can also cause the solenoid to break. Sometimes debris can cause the solenoid to become stuck open. Symptoms Of Worn Out or Broken VCT Solenoid 1. Several symptoms can show a worn out or broken Variable Valve timing solenoid. They help in indicating a problem with the VCT solenoid. There are few warning signs that one should be aware of to reduce the potential of these severe situations occurring. When a variable valve timing is broken or worn out, several other problems may occur, extending to complete engine failure. What Happens When The Variable Valve Timing Is Broken If you decide to purchase a new VCT solenoid, or additional replacement parts, here are some important ones: In cases whereby the VCT solenoid is activated, oil is sent to lubricate the VCT gear assembly.īesides, failure or blocking of the VCT solenoid and happens that there is a lack of proper lubrication, then it means that will cause the timing gear and chain to break entirely or prematurely wear. However, in a situation whereby the variable valve timing is activated, then the oil is sent to lubricate the variable valve timing gear assembly and chain. Some of these instances include while a motor vehicle is traveling up hills, carrying additional weight or when acceleration is expedited through throttle control. The system, in most cases, typically activates in situations like when there is a significant load against the engine. In most cases, they also rely on a VCT solenoid that is fully functional to control the oil flow to the variable valve timing system as it is engaged. It is important to note that each automotive manufacturer has a unique variable valve timing system. Variable valve timing in today’s time can be virtually found in all production vehicles sold throughout the United States. It was a new system that applied advanced electronic technology to apply variable electronic signals by way of a variable valve timing solenoid from the ignition system. The development of variable valve timing is one of the most significant breakthroughs. They were also able to squeeze every ounce of horsepower manually out of their drivers by just adjusting ignition timing and valve lash. The big two learned more about the performance of the engine with every new car they produced. They would also drag strips across the globe. In the early 1960s, American giants like General Motors and Ford ruled the streets. Sometimes, you may have an issue where the VCT solenoid is stuck open. However, it also uses a hydraulic valve that is electronically controlled hence able to direct high-pressure engine oil into the camshaft phaser cavity. Compared to other engines oil with fixed camshafts, it seems to be more efficient. The technology allows reduced emissions, more optimum engine performance, and increased fuel efficiency. Variable Camshaft Timing is a technology developed by a Ford which uses automobile variable valve timing. (Last Updated On: October 4, 2020) Why Is My VCT Solenoid Stuck Open?
