What are symptoms of a bad or failing variable valve timing (VVT) solenoid @UrbanAutomotive01
Показать описание
In today's video Iain and Mike discuss a common problem with the Chevy 2.4 L engines and they explain in detail how they sourced this particular drivability problem of the vehicle stalling while driving.
Common signs of a faulty VVT solenoid include the check engine light coming on, dirty engine oil, rough engine idle and decreased fuel economy.
Each automotive manufacturer has their own unique VVT system, but most of them rely on a fully functional variable valve timing solenoid to control the flow of oil to the VVT system as it is engaged. This system typically activates when there is a significant load against the engine. Some examples of this include while a vehicle is carrying additional weight, traveling up hills, or when acceleration is expedited through throttle control. When the VVT solenoid activates, oil is sent to lubricate the variable valve timing chain and gear assembly. If the VVT solenoid brakes or is blocked, the lack of proper lubrication can cause the timing chain and gear to prematurely wear or break entirely.
There are several other problems that may occur when a VVT solenoid is wearing out or has broken that may extend to complete engine failure. In order to reduce the potential of these serious situations occurring, listed below are a few warning signs to be aware of that might indicate a problem with the VVT solenoid. Here are a few symptoms of a worn out or broken VVT solenoid.
Your check engine light will become illuminated. Since today's modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU. When one part is beginning to fail, the ECU will store a specific trouble code that will let a mechanic using a scan tool know that a problem exists. Once the code has been generated, it will signal the driver by illuminating a specific zone warning. The most common light to illuminate when a VVT solenoid is failing is the check engine light.
Due to the fact that every automotive manufacturer has different codes they utilize, it's critical for a car owner to contact a local ASE Certified mechanic to inspect the car, download the code through the correct diagnostic scan tool and determine the precise source of the problem. In fact, there are literally dozens of individual codes for VVT solenoid issues for every automotive manufacturer. Once the mechanic has this initial information, they can begin to resolve the specific issue.
Dirty engine oil is more of a cause as opposed to a symptom. The VVT solenoid works best when the engine oil is clean, free of debris, or has lost some of its lubricity or viscosity. When the engine oil becomes clogged with dirt, debris or foreign particles, it tends to clog up the passageway from the solenoid to the VVT chain and gear. If your engine oil has not been changed out on schedule, it could damage the VVT solenoid, the VVT chain, and the gear drive.
To avoid this situation, make sure to have your engine oil changed as recommended by the vehicle manufacture. Low oil levels can also cause problems with the VVT solenoid and other timing system components.
You may experience rough engine idle .Typically the VVT system does not activate until the engine is at higher RPM or is introduced to load bearing situations like driving uphill. However, if the VVT solenoid is malfunctioning, it is possible that it will introduce additional engine oil to the VVT gears. This can cause the engine to idle rough, specifically the engine RPM to fluctuate as the system is activated. If not checked quickly, it can cause additional engine components to wear prematurely. If your engine idle is rough, make sure to have a certified mechanic inspect this as soon as possible.
You may experience reduced fuel economy. The purpose of variable valve timing is to ensure that the valves open and close at the right time to maximize engine performance and reduce fuel consumption. When the VVT solenoid is malfunctioning, the entire system can be compromised, which may result in intake and exhaust valves opening and closing at the wrong time. This typically causes the fuel economy to drastically reduce.
If you recognize any of the above warning signs of a bad or failing variable valve timing solenoid, contact a local licensed service provider or dealer
