That said, it could lead to either an electrical short or overload of circuits within this particular system, which will cause damage over time if left unchecked. Sputtering Modeīad electrical wiring can also cause sputtering engine problems due to faulty VTEC solenoid and bad wiring connections on these circuit boards. So, the remedy to this issue is to replace your engine oil regularly to avoid harming the VTEC solenoid. In addition, if you have a check engine light on your dashboard and your engine oil is filthy, the VTEC solenoid has most likely failed. So, if your engine oil contains a lot of contaminants, it will reduce its viscosity, blocking the VTEC solenoid system then, if the problem is not resolved quickly, it will result in destruction. However, when your engine oil is clean, this critical component generally operates optimally. Filthy Engine OilĪnother typical sign of a faulty VTEC solenoid is filthy engine oil. Therefore, to avoid leaking, keep an eye on the rubber gasket and consider replacing it regularly. Of course, it signifies that the VTEC solenoid enclosure prevents full engine oil pressure from being applied.įurther, the inserted rubber gasket typically hardens and shrinks over time, resulting in an oil leak that increases as the rubber keeps shrinking and hardening. The VTEC solenoid’s primary objective is to enable oil to flow to the interior galleries of the overhead camshaft. Oil LeakageĪnother sign of a significant engine oil spill is slowed and worsens with time. Read More: Why Is My Steering Wheel Hard To Turn? (11 Reasons Why) 4. Therefore, to improve fuel efficiency, the ideal remedy in this circumstance is to change the damaged VTEC solenoid with a fresh new one. So, if you observe that the fuel economy of your Honda vehicle has dropped significantly, the VTEC solenoid has likely ceased. As a result, if your VTEC solenoid fails, your fuel economy will suffer. Decreased Fuel EfficiencyĪ VTEC solenoid’s primary function is to manage the open and close timing of the valves to improve fuel economy. Most modern engines are automated and will notify you as soon as they discover a problem. ![]() Of course, the light may activate if the solenoid fails or there is an issue with its connectivity to the entire system, like so much pressure. Check Engine Light Display On DashboardĪfter a period of driving, the Check Engine Light displays: It is among the most prevalent symptoms of a defective VTEC solenoid. If your Honda VTEC solenoid fails, the valve frequency does not advance or retard as it should.Īs a result, the engine suffers from performance concerns such as choppy idle and weak acceleration. Look what I found out about it! Honda VTEC Solenoid SymptomsĪmong the most common signs of a faulty VTEC solenoid is a poor idle at low RPM that only clears at high RPM. Variable Valve Timing and Lift Electrical Control (VTEC) is a mechanical and electronic technology that enables your engine to have multiple camshafts. The Honda VTEC solenoid regulates the oil flow into the inner galleries of your vehicle’s overhead camshaft.
