How does VTEC work on a Honda?
The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance. And the transition occurs seamlessly, allowing for smooth performance across the entire powerband. The switching operation between the two cam lobes is controlled by the engine computer.
Why does my Honda Accord have variable valve timing?
It can get dirty and cause P2646. The VTEC system controls the variable valve timing in your Accord. It does this by activating the VTEC/Rocker arm solenoid. It uses the Rocker Arm oil pressure switch to monitor the pressure of this system.
What does VTEC stand for in Honda valve timing?
VTEC is a type of variable valve-timing system developed and used by Honda. It stands for V ariable Valve T iming & Lift E lectronic C ontrol. Like most other variable-valve timing systems, VTEC…
When was Honda’s variable valve control system introduced?
Unsourced material may be challenged and removed. VTEC, the original Honda variable valve control system, originated from REV (Revolution-Modulated Valve Control) introduced on the CBR400 in 1983 known as HYPER VTEC. In the regular four-stroke automobile engine, the intake and exhaust valves are actuated by lobes on a camshaft.
Where is the VTEC switch located on a Honda engine?
The intake and exhaust rocker shafts contain primary and secondary intake and exhaust rocker arms, respectively. The primary rocker arm contains the VTEC switching piston, while the secondary rocker arm contains the return spring. The term “primary” does not refer to which rocker arm forces the valve down during low-RPM engine operation.
