What can cause a VVT to go bad?
If your oil is dirty, sludge can clog the screen on the solenoid, causing a failure. If the engine oil level is low, you will also experience problems with VVT operation.
What happens when the VVT solenoid is blocked?
When the VVT solenoid activates, oil is sent to lubricate the variable valve timing chain and gear assembly. If the VVT solenoid fails or is blocked, the lack of proper lubrication can cause the timing chain and gear to prematurely wear or break entirely.
Why is my VVT chain not working properly?
When the engine oil becomes clogged with debris, dirt or other foreign particles, it tends to clog up the passageway from the solenoid to the VVT chain and gear. If your engine oil has not been changed out on schedule, it could damage the VVT solenoid, the VVT chain, and the gear drive.
What are the symptoms of a failing VVT switch?
Just like any other mechanical or electrical component, the VVT switch is prone to wearing out or breaking completely. In many ways, the symptoms of a failing VVT switch are similar to the symptoms of a VVT solenoid. The most common cause of failure for both the VVT switch and the VVT solenoid is a lack of basic maintenance.
What causes a VTEC control solenoid to go bad?
If your fault is NOT due to a faulty pressure switch, or an electrical circuit fault to or within the PCM, then it is either a bad VTEC control solenoid, sludge clogging the oil circuit OR low oil pressure / oil starvation. Good luck! IT IS ALREADY BROKEN DOWN AGAIN!!! The dealer where you bought it? A non -Honda dealer, right? Click to expand…
Why is my VVT not working properly on my car?
Roughness in Idling Engine The passing of additional oil to the VVT gears is a possibility if the system is not working properly. This very phenomenon manifests itself in the rough idling of the engine. It is primarily because the engine’s RPM fluctuates as the VVT starts working.
What are the most common problems with VTEC?
The most common VTEC issues we see are, in order of frequency: very low engine oil levels that result in starvation under hard accelleration, faulty VTEC oil pressure switches, faulty VTEC oil control solenoids, sludged / clogged oil passages in the VTEC oil control circuit, wiring harness / connector terminal damage, bad PCM.
How to fix the VTEC on a Honda Element?
Either clean the wire filter in the vtec control module or change out the entire VTEC control on the back of the engine. Or. And here is my fix of choice. Change the oil and use 10w30. The additional pressure will help the vtec. I have run 10w30 since my first oil change and never an issue.
