Why is my vtec not kicking?

If your VTEC is not kicking in, it could be due to several reasons, such as a faulty VTEC solenoid, low oil levels, or a clogged oil filter. Additionally, issues with the VTEC pressure switch or a malfunctioning engine control unit (ECU) can prevent VTEC activation. It's also important to check for any engine trouble codes that might indicate the source of the problem. Regular maintenance and addressing any issues promptly can help ensure proper VTEC function.
