Which Honda engines have VCM?
Honda's Variable Cylinder Management (VCM) technology is a fuel-saving feature found in select Honda engines. VCM allows the engine to automatically deactivate some of its cylinders under light load conditions, such as cruising at highway speeds, to improve fuel efficiency.
Which Honda Engines Have VCM?
Honda has incorporated VCM technology into several of its engine lineups over the years, including the following:
- V6 Engines: Honda's VCM technology is most commonly found in their V6 engines, such as the 3.5L V6 used in the Accord, Pilot, and Odyssey models.
- Turbo Engines: More recently, Honda has also introduced VCM in some of their turbocharged 4-cylinder engines, like the 1.5L and 2.0L turbo units found in the Civic and Accord.
- Hybrid Engines: Honda's hybrid vehicles, including the Accord Hybrid and Insight, also utilize VCM to further improve fuel efficiency by deactivating cylinders when the electric motor is providing the majority of the power.
By selectively deactivating cylinders, VCM helps Honda engines maintain good performance while delivering improved fuel economy, especially during highway driving and other light-load conditions.
How Does VCM Work?
Honda's VCM system uses advanced engine management software and electromechanical components to seamlessly activate and deactivate individual cylinders as needed. When the engine is operating under light loads, VCM can shut off up to half of the engine's cylinders, reducing fuel consumption and emissions. When more power is required, the deactivated cylinders are instantly reactivated.
This cylinder deactivation technology is a key part of Honda's efforts to improve the fuel efficiency of their vehicles without sacrificing performance. By intelligently managing the engine's operation, VCM helps Honda owners get the most out of every gallon of gas.
What is the difference between 2024 and 2025 Honda Pilot?
The 2025 Honda Pilot offers a more streamlined trim line-up, with the discontinuation of the base LX trim and the EX-L seven passenger trim, and the addition of the new Black Edition as the top model.
Which VCM disabler is best?
You should seriously consider the S-VCM Controller for its advantages: it is safer, more reliable, and backed with an 18-month product warranty. This innovative product offers the best performance value, and more importantly peace of mind for its reliability and safety features.
What year did Honda Pilot get VCM?
For the 2006 model year, Honda added Variable Cylinder Management to the two-wheel-drive models. This VCM tech proved to be problematic in some cases, which led to a class action lawsuit for Honda Motor Co.
Does the Honda V-6 have cylinder deactivation?
When maximum power isn't needed, the VCM system can deactivate one bank of cylinders—depending upon the torque requirements to maintain cruising speed—by shutting off the appropriate fuel injectors and stopping valve operation with the VTEC® system.
What Honda engines have VCM?
Vehicles equipped with VCM
2008–2017 Honda Accord V6 (except EX-L V6 6MT Coupe) - 2008-2012 models are equipped with VCM-2 (3-, 4-, and 6-cylinder operation) - 2013-2017 models are equipped with VCM-3 (3- and 6-cylinder operation).
Which cylinders does the Honda VCM deactivate?
Intro to Variable Cylinder Management Technology
The 2005-2007 Honda 3.5L V6 is a VCM-1 engine and only does cylinder deactivation on cylinders 1-3 instead of 1-4 like the VCM-2 engine.
What engines have active fuel management?
GM used the Active Fuel Management technology on a range of engines including with the GM Small Block Gen IV engine family, first-generation GM EcoTec3 engine family, second-generation GM High-Feature V6 DOHC engine family, and first-generation High-Feature V8 DOHC engine family.
Can you turn off a Honda VCM?
Position 40,50,60 (Disable VCM) is tunable between different climates. Users who have had to replace CTS sensors will now have a very precise way of disabling VCM as well as calibrating the dash temperature gauge. For cold climates like Alaska, a setting of 35-40 will work in most cases.
Do Honda Ridgelines have VCM?
Ridgeline is powered by a direct-injection V-6—a 3.5-liter, aluminum-alloy, single-overhead camshaft, 24-valve i-VTEC engine featuring Honda's advanced Variable Cylinder Management™ (VCM®) system.
Does the 2025 Pilot have VCM?
Does the 2025 Honda Pilot have VCM? Yes, the 2025 Honda Pilot is equipped with Variable Cylinder Management (VCM). This system is designed to switch between six and three cylinders based on driving conditions, optimizing fuel efficiency.
