What happens if your oil control valve goes bad?
An oil control valve (also referred to as a VVT solenoid) is an important component of a vehicle with a variable valve timing (VVT) system. The existence of the system aims to control the performance of the engine utilizing two methods to retard and advance camshaft angle. If your oil control valve goes bad, you’ll have problems.
What happens to the rocker arms without oil?
Without oil, internal engine components, such as rocker arms, will overheat and may scrape against their mating surface, instead of sliding. The ECM uses sensors such as a rocker arm actuator, or oil pressure switch, to regulate the flow of oil to the engine.
What to do about Honda rocker arm oil pressure switch?
Before replacing any parts change the engine oil with the factory recommend oil weight. The factory bulletin suggests that replacing the VTEC oil pressure switch (P/N 37250-PNE-G01, H/C 6737217) take care of the problem. The cost of diagnosing the P2647 HONDA code is 1.0 hour of labor.
How can I check the oil control valve?
One can check for this, by accelerating the car and noting the time taken to reach the desired speed. In simple words, if the car is unable to reach a 60km/h speed in a short time, then it’s the sign of disturbance in the oil control valve.
Can a rocker arm oil control valve be replaced?
If I had to guess, pieces of the first broke and got stuck in the camshaft cover. If you replace the valve and any little pieces broke off they are stuck in the cover. You can replace the rocker arm oil control valve over and over and the pieces are still stuck in the cover impeding oil flow.
What is trouble code for rocker arm actuator?
The definition of this code is ” ‘A’ Rocker Arm Actuator System Performance/ Stuck off Bank 1″. So as you can see, it is very difficult to understand anything about this code with just this definition so in case you are getting this trouble code this article will be very informative to you.

When to replace a variable valve solenoid ( VVT )?
Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. Once you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
How to check oil control valve in Toyota?
“…Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve. NOTICE: Confirm that the valve moves freely and does not stick in any position”. Loading…
What are the functions of an oil control valve?
In general, an oil control valve has several functions that are vital. These include: saving fuel usage, reducing gas emissions generated by the vehicle, and improving engine performance as efficiently as possible.
How does VVT-variable valve timing work?
Variable Valve Timing (VVT) is a way to advance/retard valve timing, and change duration, overlap and even lift in some applications while the engine is running. VVT is computer-controlled and typically uses oil pressure to change the position of a phaser mechanism on the end of the camshaft to advance or retard cam timing.
How often to use valve oil?
Oil the valves frequently. You do not need to oil the valves each time you play, but it is important to oil them 2-3 times each week or whenever the valves are not moving as efficiently as possible. This will help keep your instrument clean, improve the instrument’s longevity, and help prevent corrosion.
What is the oil control valve in a car?

What is the advantage of variable valve timing?
Top 4 Advantages Better Engine Performance. When you put more demand on your engine, it needs to have more revolutions per minute (RPM). Better Gas Mileage. Without variable valve timing technology, an engine must work harder and consume more fuel just to satisfy the demands being placed on it by the driver. Reduced Carbon Emissions. Higher Engine Longevity.
