What does a Honda spool valve do?
Spool valves can be used in both hydraulics (where the oil is the energy source) or Pneumatics (where the air is the energy source) and their job is to control the flow direction of the energy source by combining or switching the paths through which the oil or air can travel.
What happens when VTEC solenoid is bad?
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. There are several other problems that may occur when a VVT solenoid is wearing out or has broken that may extend to complete engine failure.
What causes a VTEC solenoid to go bad?
The fact the solenoid continuously fails may indicate that electrical side or mechanical side behind it is not working properly. These assemblies can clog and cause issues with the solenoid. You can replace or clean the assembly if needed. If the assembly is fine, you will want to turn to electrical testing.
What are the symptoms of a bad VCT solenoid?
Common VVT Solenoid Failure Symptoms
- Rough Engine Idle.
- Check Engine Light.
- Misfiring engine under loads.
Can a bad VVT solenoid cause a no start?
Can a bad VVT solenoid cause a no start? When solenoid goes bad, the passage of current gets interrupted resulting in a problem in starting. This could be because of burn or corroded contacts. In case of VVT Solenoid’s malfunctioning, improper lubrication can result in gear and timing chain damage.
Will a bad VVT solenoid cause a misfire?
A faulty VVT switch will also cause the engine to misfire or appear to stumble when your vehicle is loaded with extra weight, climbing hills, or when you apply quick pressure to the throttle for instant acceleration. This is caused commonly by an electrical issue with the switch and not always the switch itself.
Where is the engine variable timing solenoid located?

How do you know if your variable valve timing is bad?
Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load.
What is a engine variable timing solenoid?
VVT stands for Variable Valve Timing, which is the system that regulates how long the engine’s different valves are open depending on the engine’s needs at the time. The VVT solenoid is the electrical part that gauges the engine’s needs based on oil pressure.
What happens when the solenoid goes bad?
When the starter solenoid decides to call it quits, the starter motor won’t work, either. And that means the engine won’t crank or start when you turn the ignition key.
