The variable valve timing solenoid is located at the front of the engine, typically near the front of the valve cover. Try looking at the new solenoid to match the shape and help you find it. The connector is the exposed end of the variable valve timing solenoid. 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.
