Use a common T-tap or other method and simply tap this into the VTEC solenoid valve wire (the VTEC solenoid wire comes from OBD1 ECU pin A4). This can be easily bypassed with a simple wiring trick: On your engine harness, locate the VTEC oil pressure switch plug/wire (this wire comes from OBD1 ECU pin D6). How do I bypass the VTEC oil pressure switch? Following the manufacture pinpoint test to isolate faults in the system.It can also cause misfires or a stalling engine together with a check engine light on your dashboard. The most common symptom of a bad rocker arm is clicking or ticking noises coming from the cylinder head of the engine. The rocker arm actuator is an oil pressure switch which controls the flow of oil to critical upper engine cylinder head components. A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). What does a rocker arm oil control valve do? Repairing or replacing wiring or connectors that are associated with the variable valve timing system.Replacing the oil control valve or other variable valve timing components.Replacing the timing belt or chain as well as other timing components.What are the symptoms of a bad VTEC solenoid? The most likely scenario with a VTEC solenoid failure is when you get a check engine light, and the car will likely go into limp mode, often leaving you fearing the worst. What are the symptoms of a bad VTEC solenoid? Expect to pay anywhere from $500 to $1,500 (parts + labor) depending on the vehicle. How much does it cost to fix a rocker arm actuator?īecause rocker arm repair is tedious work, it can be time intensive so hiring an auto mechanic or dealership to do the job is not cheap. VTEC is a variable valve timing system developed by Honda to improve your vehicle’s fuel efficiency.
