What causes a VCT solenoid to go bad?
The engine oil being unclean and filled with debris is more of a cause of the VCT solenoid having issues since the VCT solenoid works best when the engine oil is clean, pure, free of debris, or lost viscosity. When the engine oil becomes clogged with debris, it can clog the passageway from the solenoid to the chain and gear.
What is a Ford VCT solenoid?
Even though it’s just a small component of Ford’s Variable Camshaft Timing (VCT) technology, it plays a big role in the overall well-being of many Ford vehicles and will need to be replaced if it’s not working properly. It’s why you should familiarize yourself with the VCT solenoid and know how to spot signs of trouble with it.

What does it mean when your VCT solenoid is conking out?
If you have very dirty oil in your vehicle, it could also be an indication that your VCT solenoid is on the verge of conking out on you. Dirty oil can do a lot of damage to a VCT solenoid and other components in a VCT system. If your engine idles rough, that could be a sign that your VCT solenoid is on its way out, too. You don’t want to spend too much time driving around in a vehicle with a rough idle since the problem could continue to get worse over time.
What does VCT do?
So, what exactly does VCT do? Well, for starters, it was designed to provide Ford owners with optimum engine performance each and every time they fire up their engines. It was also designed to reduce the emissions produced by Ford vehicles while improving fuel efficiency, especially when compared to other vehicles that rely on fixed camshafts. It’s able to do these things through the use of a complex process that utilizes camshaft phasers, electronically controlled hydraulic valves, VCT solenoids, and a powertrain control module to better control the timing of the camshaft.
What engine did Ford use for the VCT?
Most notably, Ford used VCT technology in the 4.6L 3-valve V8 engine that it used in Ford Explorers from 2006 through 2010 in addition to Ford Mustang GTs from 2005 through 2010. It was also used in the Triton 5.4L 3-valve V8 engine for some time.
Where are VCT solenoids located?
These solenoids are strategically positioned on the cylinder heads that are located towards the front of an engine in a Ford vehicle, right next to the camshaft phasers. They work by accepting a signal from the powertrain control module and helping to regulate the flow of oil moving in the direction of the cavity in the camshaft phaser. This flow would be disrupted without fully-functioning VCT solenoids in place.
Can a bad VCT solenoid cause a car to give out?
In fact, your whole car might give out on you if you drive around with a bad VCT solenoid for an extended period of time.
What is a VCT solenoid?
A VCT, also known as a variable camshaft timing, is an automobile variable valve timing technology that has been developed by Ford, one of the biggest American Automotive companies in the entire United States and the world.
Why is my VCT solenoid not working?
The engine oil being unclean and filled with debris is more of a cause of the VCT solenoid having issues since the VCT solenoid works best when the engine oil is clean, pure, free of debris, or lost viscosity. When the engine oil becomes clogged with debris, it can clog the passageway from the solenoid to the chain and gear.
Why does my VCT start idling rough?
A malfunctioning VCT solenoid can cause the engine to begin idling rough, especially if the engine RPM starts to fluctuate as the system is beginning. If this issue does not check quickly, additional parts of the engine can wear out prematurely and cause more parts to break down quicker.
Why does my VCT not turn on?
Usually, the VCT system does not turn on until the engine is operating at a higher and faster RPM, or if the engine is introduced to a load-bearing situation, as in if you are towing a heavy item or driving uphill continuously. However, if your VCT Solenoid is malfunctioning or not working at an optimal level, it can introduce additional engine strain and oil to the VCT gears.
How does a solenoid work?
A solenoid is a type of electromagnet that generates a controlled magnetic field through a coil that is wound tightly and can be arranged to produce a uniform magnetic field. These oil control solenoids bolt directly into the cylinder heads near the front of the engine, directly next to the camshaft-phasers. The powertrain control module, also ...
Why do we need variable valve timing?
The main purpose of variable valve timing is to ensure valves are open and close at the proper moments to maximize engine performance and reduce unnecessary fuel consumption, increasing fuel efficiency and miles per gallon.
Where is the VCT located?
Locate the VCT Solenoid. The VCT solenoid is basically within the engine itself, located right near the valve cover. If you have the new solenoid that you will be using as the replacement, this can help you identify the faulty solenoid in your car. You will be able to see the connector at the exposed end of the VCT Solenoid ...
What to do if engine oil is clean and OCV circuits are OK?
If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.
What is a VVT valve?
The Variable Valve Timing (VVT) system controls intake valve timing in response to driving conditions.
What is the code for a VVT?
A P0010 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0010 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine).
Can you swap a VVT valve?
Very easy to swap the vvt valve,but that will not guarantee to rectify the problem,more than likely it will be the vvt pulley/timing unit,this will involve the timing belt coming off.
How to clean a VVT?
You may get lucky by trying to clean the VVT by adding a can of Seafoam to your engine oil and running it in there for the next 250 miles and then giving the Trailblazer oil and filter service with the recommended 5W-30 weight oil, anything heavier may cause the VVT not to function correctly as it is now.
Why does my VVT solenoid jam?
You usually can't fix them, unless you remove the solenoid from the end of the CAM shaft. They VVT solenoid, usually jams up because of dirty oil sludge, deposits , oil not being changed as often as it should be. Some have taken the VVT apart and fixed them, search You Tube, most either buy a new one...Pretty expensive, or take it to the dealer to have it fixed, still expensive.
What is variable valve timing?
Variable valve timing (vvt-i) works with oil pressure, if your oil is dirty or low it would set this code, if somebody did a big engine job and use too much silicon base gasket that gasket can travel all the way to oct filter and clog it, starving the vvt gear.
Why is my VVT so dirty?
The VVT (variable Valve Timing) solenoid may be dirty and will need to be cleaned or replaced. Poor maintenance (lack of oil change) will cause carbon and sludge to accumulate on the VVT screen causing the VVT to stick which will cause the issues your experiencing.
What to do if engine oil is clean and OCV circuits are OK?
If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.
Can you clean injectors with seafoam?
Seafoam and other additives are very good solvents that can help clean the injectors - but may not be strong enough to clean off these injectors. Injector cleaning services generally don't work that well - best way is to have these cleaned ultrasonically or replaced (very costly).
