Where is the solenoid on a Honda Civic Si?
You can hunt down your exact replacement procedure by searching for Honda Vtec solenoid replacement on YouTube. On the Honda Civic SI and the accord with the 2.3 L or 2.4 L four-cylinder Honda engines we find the VTEC solenoid on the left rear of the cylinder head.

What does the VTEC solenoid do on a Honda Accord?
The VTEC solenoid actually allows oil to flow to the internal galleries of the overhead camshaft. This means that the housing of the solenoid is holding back full engine oil pressure. Unfortunately, the generous rubber gasket installed from the factory isn’t aging as well as Honda engineers hoped. In fact, the rubber starts to harden and shrink.
What causes oil leak in Honda VTEC solenoid?
In this particular automobile, we traced the failure down to a defective valve timing oil pressure switch. This little device threads into the Honda VTEC solenoid assembly. Upon further inspection, we found a small oil leak coming from the bottom corner of the solenoid housing.
What does VTEC solenoid do?
The VTEC solenoid mounts to the engine head, and allows the flow of oil into small passages that change the camshaft profiles, causing the engine to perform faster. This is not to be confused with the VTC solenoid, which advances or retards the variable valve timing gear to change engine timing.
How does VTEC work?
VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine’s computer can activate alternate lobes on the camshaft and change the cam’s timing.
What is a VTEC engine?
VTEC is an acronym for Variable valve Timing and lift Electronic Control. It is a mechanism for optimizing air/fuel mixture flow through the engine. An internal combustion engine converts the chemical energy stored in fuel into thermal energy.
