How does a VTEC system work?

How does a VTEC system work?

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.

Is the VTEC engine good?

Yes, Honda VTEC engines are VERY good because they’re engines that run more efficiently than engines without variable valve timing, literally have two personalities in one engine, very reliable mechanical system, and they have a unparalleled high horsepower for a naturally aspirated engine with just 4 and 6 cylinders.

Does VTEC increase horsepower?

VTEC is a type of variable valve-timing system developed and used by Honda. At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower.

What Honda Motors are VTEC?

Honda Models with VTEC For Civics the EX, EX-L, HX (6th generation), Si, Si-R, VTi VTiR and Civic Type R (CTR) are VTEC.

Does VTEC have Turbo?

The VTEC TURBO engine produces more torque than the 2.4L naturally-aspirated engine, thanks to its turbo. The VTEC TURBO allows a small, 1.5L engine to perform as well as a 2.4L engine.

Can you feel VTEC kick?

Re: What does it feel like when VTEC kicks in? ( the GSR has a lower switch point than most other dohc vtec cars, and its tuned to be very smooth and transparent. So if the car is stock, you won’t feel any abrupt switch. you might hear it though, if you listen carefully. with intake and exhaust, its easier to hear.

At what RPM does VTEC kick in?

It engages anywhere between ~2300-3800 rpm, depending on conditions. And the engagement point will generally not be as noticeable as with DOHC VTEC engines. Thag, Generally, at higher rpm, it is more efficient to open the intake and exhaust valves for a longer time, thus the longer duration and different grinds.

How can I make my Honda VTEC faster?

How to Make My Honda Civic Faster

1. Add horsepower. One of the first steps you can take to make your Civic faster is to add more horsepower to the engine.
2. Increase the handling. A Civic that is faster is not only faster in a straight line but faster around corners as well.
3. Upgrade the brakes.
4. Remove weight.

What happens when VTEC doesn’t work?

Oil Pressure A lack of oil pressure, enough oil or similarly related lubrication issues can cause problems with your VTEC system. Without the proper oil pressure the VTEC pressure switch will not tell the ECU that it’s safe to pressurize the VTEC oil system which will push the VTEC locking pins in place.

Can you drive with a bad VTEC solenoid?

Unplugging the solenoid won’t damage your motor, it will just run like poop above 6k. With the VTEC solenoid unplugged (in my MY04) it won’t be able to sense when to kick over to the high lift cams. The engine will not rev over 6K, it works similar to a rev limiter.

How do I fix VTEC system failure?

The most common cause for Error Code P1259 or VTEC system malfunction is low oil pressure. Thus, make sure you check your oil if it’s due for service. Change oil and filter if necessary. Clear the codes and then give it a try.

How much does it cost to replace a VTEC solenoid?

The average cost for a Honda Accord variable valve timing control solenoid replacement is between $217 and $230. Labor costs are estimated between $50 and $63 while parts are priced at $167.

What are the symptoms of a bad VTEC solenoid?

Symptoms of a Bad or Failing Variable Valve Timing (VVT) Solenoid

• Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
• Engine oil is dirty.
• Rough engine idle.
• Decrease in fuel economy.

Where is the VTEC solenoid located?

On the Honda Civic SI and the accord with the 2.3 L or 2.4 L four-cylinder Honda engines we find the VTEC solenoid on the left rear of the cylinder head. The VTEC solenoid housing also provides a threaded hole for the oil pressure switch and o-ring we speak of in the diagnosis section above.
