This component is electrically operated by the engine computer.
It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing.
It is very similar to the solenoids in use inside an automatic transmission.

on the engine exhaust cam ..at the front of the cam .
I think you mean the Variable Camshaft Timing Solenoid or VCT Solenoid (F8CZ-6L713-AA) used on 4 cyl engine. It is located under the camshaft cover on the on the exhaust camshaft.
I had two changed on my 2000 Avalon, and I paid about $350, parts and labor.
It is an error code that says the variable valve timing is out of limits, may need a timing adjustment or a new vvt solenoid
According to Wikipedia, a variable valve timing is a "process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions".
A VTC (Variable Timing Control) solenoid is an essential component in an engine's variable valve timing (VVT) system. It regulates the flow of oil to the VVT actuator, allowing for adjustments in the timing of the intake and exhaust valves based on engine speed and load. This optimization enhances engine performance, fuel efficiency, and reduces emissions. When malfunctioning, a VTC solenoid can lead to poor engine performance or increased emissions.
The Variable Valve Timing (VVT) solenoid on a 2006 Toyota RAV4 with a 2.4L engine is located on the front of the engine, near the timing cover. It is typically positioned near the intake camshaft. To access it, you may need to remove some engine covers or components obstructing the area. Always consult the vehicle's service manual for specific details and guidance.
Variable timing valve train
Variable valve timing.
variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft
the variable cam timing (VCT) solenoid on the ZX2 can be found on the same side of the engine as the cam gears are on. The parts of the VCT are located on the exhaust cam and between the two cams
