Where is the intake valve control solenoid located?
The intake valve control solenoid is a critical component in modern vehicles, playing a key role in optimizing engine performance and fuel efficiency. If you're experiencing issues like rough idling, reduced power, or a check engine light, the intake valve control solenoid might be the culprit. In this article, we’ll explain where this part is located and provide some tips for identifying and addressing potential problems.
What is the Intake Valve Control Solenoid?
The intake valve control solenoid is part of the variable valve timing (VVT) system in many vehicles. This system adjusts the timing of the intake valves to improve engine efficiency, power output, and emissions. The solenoid controls the flow of oil to the VVT system, allowing it to adjust the camshaft timing as needed.
Where Can You Find the Intake Valve Control Solenoid?
The exact location of the intake valve control solenoid can vary depending on the make and model of your vehicle. However, it is typically found in one of the following areas:
- Near the Engine Cylinder Head: In most vehicles, the solenoid is mounted on or near the cylinder head, close to the intake camshaft. This placement allows it to directly control the oil flow to the VVT system.
- On the Valve Cover: In some designs, the solenoid is located on the valve cover, making it relatively easy to access for inspection or replacement.
- Connected to the Timing Chain Cover: In certain vehicles, the solenoid may be integrated into the timing chain cover, as it works closely with the timing components.
To locate the intake valve control solenoid in your specific vehicle, consult your owner’s manual or a repair guide for your car’s make and model. You can also look for a small, cylindrical component with an electrical connector and oil passages near the areas mentioned above.
Signs of a Faulty Intake Valve Control Solenoid
If the intake valve control solenoid is malfunctioning, you may notice the following symptoms:
- Check Engine Light: A faulty solenoid often triggers the check engine light, accompanied by diagnostic trouble codes (DTCs) related to the VVT system.
- Reduced Engine Performance: You might experience a loss of power, poor acceleration, or rough idling.
- Increased Fuel Consumption: A malfunctioning solenoid can lead to inefficient engine operation, resulting in higher fuel consumption.
- Unusual Engine Noises: Clicking or ticking sounds from the engine could indicate an issue with the solenoid or related components.
What to Do If You Suspect an Issue
If you suspect that your intake valve control solenoid is faulty, follow these steps:
- Inspect the Solenoid: Check for visible damage, oil leaks, or loose connections around the solenoid.
- Scan for Diagnostic Codes: Use an OBD-II scanner to retrieve any trouble codes that might point to a solenoid issue.
- Consult a Professional: If you’re unsure about diagnosing or replacing the solenoid yourself, bring your vehicle to a trusted auto repair shop like Kevin’s Autos for expert assistance.

Frequently Asked Questions
Where is the intake valve actuator solenoid located?
Cam position actuator solenoid valves are usually located on the intake and exhaust sides of the engine, tightly mounted on the engine. The exact location may vary from model to model and manufacturer to manufacturer, but they are usually on the valve covers or cylinder heads above the engine.
Can you drive with a bad intake solenoid?
Even though you may technically be able to continue driving with a bad VVT solenoid, the issue can cause damage to additional parts, such as the VVT actuator. So, you should address the issue as soon as possible.
Where is the intake valve solenoid?
In most vehicles, the intake valve control solenoid is usually found on the intake manifold side of the cylinder head. To understand this code better, let's discuss how VVT and VVL systems work. If you're interested in a DIY fix for P0026, you should read our advanced technical discussion about camshaft angle and VVT.
How do you know if a solenoid is faulty and needs replacing?
The next bad starter solenoid symptom is a clicking. Noise if you hear a single click the solenoid is engaging. But it's not providing enough power to the starter.
What is the difference between a solenoid valve and a solenoid actuator?
Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.

If you're interested in a DIY fix for P0026, you should read our advanced technical discussion about camshaft angle and VVT.
Can you drive with a damaged solenoid?
Is It Safe to Drive With a Bad Solenoid? You can still drive your vehicle even if it has a malfunctioning transmission solenoid. However, it isn't recommended. Driving with a bad transmission solenoid can damage your transmission even more, leading to costly repairs.
What are the symptoms of an intake valve control solenoid circuit?
Your engine may run rough, hesitate, or stutter while idle or driving. You may also notice that your vehicle consumes more fuel than usual.
What happens when a solenoid valve goes bad?
Malfunctioning: When a solenoid valve fails, the valve may not open or close completely. This can cause fluid flow to be interrupted or restricted. Slow Response: When a solenoid valve fails, the valve may respond more slowly to commands than normal. This can lead to delays or problems in system performance.
What happens if the intake solenoid goes bad?
If the solenoid is stuck open, it can create a vacuum leak, leading to a lean air-fuel mixture and affecting engine performance. Rough Idle or Stalling: If the solenoid is malfunctioning, it can disrupt the air-fuel mixture, leading to rough idling, stalling, or difficulty starting the engine.
