What is vtec solenoid

This is caused commonly by an electrical issue with the switch and not always the switch itself. If the VVT solenoid in your car is faulty, it can cause the engine to idle rough. The engine RPM will fluctuate which can directly result in a reduction of power generated by your car.

A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. It then accordingly controls the camshafts which are the mechanical parts responsible for opening and closing engine valves. If you look inside the sensor, there is a heated wire, and behind that is another wire which picks up the oxidized air. Stick the tube which is attached to the electronics cleaner spray can into the cavity where these wires are seen.

Then I put the alcohol soaked rag on the end of a screwdriver, stuff it into the solenoid base and twist. In addition to the check engine light, the customer complained of, lack of power and bucking before shifting gears. On a road test I found that the vehicle didn't want to go over RPMs. In this particular automobile, we traced the failure down to a defective valve timing oil pressure switch. Upon further inspection, we found a small oil leak coming from the bottom corner of the solenoid housing.

For this reason we decided to pull the assembly off of the Honda Accord and take a look at it on the bench. What we found was a deteriorating gasket. In this situation, I laid the repair options out for the driver. Obviously, replacing the gasket and the VTEC pressure switch would be the lowest cost option. Then we called the dealership to price these two parts. When the driver decided to go online and shop around they found a complete assembly for less than the cost of the gasket from the local Honda dealership.

We're also going to explain the major difference between the variable valve timing systems of a Honda automobile when compared to VVT problems with General Motors cars. Before we move on let's finish up the story about this Honda Accord.

When the customer drove over to the local Honda dealership, he talked to the service department about what the repairs would cost through the dealership. Of course, the service writer wanted to verify the failure before quoting prices.

In this article we'll cover some repair tips and talk about the best way to access these components. Hint, you don't want to go in from the top and you probably want to pull off the wheel to gain access on a CRV.

The general or most common Honda VTEC system problems produce symptoms that fall into two major categories. The first one is a failure of the system to engage the high lift, longer duration lobe of the camshaft. We'll get into how the VTEC system works at the end of this article. For now what we need to understand is the VTEC function is requested by the vehicles main computer.

Long story short, the computer energizes the VTEC solenoid and the spool valve. There are a couple of different codes that set depending on the defect in the system. With that said, the P trouble code is the one I see most often. This trouble code often leads to parts replacement, but still needs diagnosis to determine which one. We'll talk more about this in the diagnostic section below. Another common symptom of Honda VTEC system problems becomes an oil leak that develops slowly, but consistently worsens over time.

The VTEC solenoid actually allows oil to flow to the internal galleries of the overhead camshaft. This means that the housing of the solenoid is holding back full engine oil pressure.

In fact, the rubber starts to harden and shrink. Our comment: There are some reasonably-priced OEM choices out there for the K-Series owners looking to replace their gasket kit, such as this one. However, we would consider opting for a whole VTEC solenoid to try and eliminate issues further down the line. Our comment: For the S owners, this genuine OEM gasket kit is ideal for attempting to fix the perished rubber gasket on your existing solenoid that may be leaking oil.

For that reason, and given the minimal price difference between the two, we would personally recommend opting for a straight swap with a new unit. In this case, it may be worth considering opting for the gasket kit initially to see whether it resolves the problem on a leaky solenoid with an obvious gasket issue, but be prepared to put in more work and perhaps have to replace the solenoid shortly after.

Whether you opt for an entirely new solenoid or a gasket replacement, we always recommend that you take extreme care when removing the bolts and ensure that both of the mating surfaces are free of contaminants and debris comes to re-fitting.

Not keeping up with frequent maintenance will often lead to clogged-up oil containing debris that can eventually clog up the passageway to the solenoid, alongside many other issues. So, there we have it! If you enjoyed this article, please share it with the buttons at the bottom of your screen.
