Why does my VTEC solenoid keep failing?
The fact the solenoid continuously fails may indicate that electrical side or mechanical side behind it is not working properly. These assemblies can clog and cause issues with the solenoid. You can replace or clean the assembly if needed. If the assembly is fine, you will want to turn to electrical testing.
What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
What’s the difference between a non VTEC and a VTEC engine?
1 VTEC engines use two camshaft profiles while non-VTEC engines only use one 2 VTEC engines can have excellent performance at high and low speeds while non-VTEC engines can only be optimized for either 3 VTEC is only available on Hondas while non-VTEC are found on any car brand 4 VTEC engines are much better than non-VTEC for street cars
How does Honda variable valve timing system work?
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 varies oil pressure to shift between different cam profiles.
When was VTEC introduced in the Honda NSX?
Since its introduction in the late 1980s, VTEC has been used in many of Honda’s best performance cars including the NSX, Integra Type R, S2000, and Civic Type R. But the way VTEC goes about switching cam profiles is totally distinct.
What kind of ECU does a Honda Accord have?
P0A – Commonly discarded by those looking to step up to the VTEC H22 Prelude engine, this ECU is found in the OBD1 1994-1995 Honda Accord EX. P13 – Great for any Honda engine swap and easily modified and chipped, this unit is in the 1992-1995 Honda Prelude VTEC using the DOHC 2.2 liter H22A engine.
When does the VTEC go on in a Honda?
It’s active when the engine is operating relatively high in the rev range, and you rarely get there in normal driving conditions, especially if your car has an automatic transmission. But, if you’re the shift-your-own-gears type and you like twisty roads, VTEC makes a noticeable difference.

How does the camshaft work in a Honda VTEC?
In the traditional engine, the camshaft controls valve opening and closing, and its lobes are all the same size. In Honda’s VTEC engine, as you saw in the video, the camshaft has two different types of lobe sizes: Two standard-sized outer lobes and a larger center lobe.
