Most modern VVT systems utilize engine oil (hydraulic) pressure and some type of an electronic solenoid to initiate changes in valve timing, lift, and/or duration. One of the most common problems found when diagnosing a VVT system malfunction is low oil pressure or low engine oil level.
Simply so, How much does a VVT cost? Variable Valve Timing Control Solenoid Replacement Cost – RepairPal Estimate. The average cost for variable valve timing control solenoid replacement is between $326 and $388. Labor costs are estimated between $138 and $175 while parts are priced between $188 and $213.
When should a VVT solenoid be replaced? If your vehicle is equipped with a variable valve timing system, it needs to operate as designed for proper performance and fuel efficiency. If your vehicle’s VVT solenoid is faulty, have it replaced as soon as possible to regain your lost performance.
Subsequently, Should I delete VVT?
Eliminating the VVT system is required when swapping to a non-VVT camshaft. These cams offer higher valve lift and longer duration for more performance. A VVT delete kit removes the VVT components and replaces them with standard parts.
What causes VVT rattle?
When should a VVT be replaced? If your vehicle is equipped with a variable valve timing system, it needs to operate as designed for proper performance and fuel efficiency. If your vehicle’s VVT solenoid is faulty, have it replaced as soon as possible to regain your lost performance.
How long does it take to replace VVT solenoid?
There is a typical labor time between 2-3 hours to replace a VVT cam gear, so removing the engine and diagnosis the problem is more complicated.
How long does it take to fix VVT solenoid? There is a typical labor time between 2-3 hours to replace a VVT cam gear, so removing the engine and diagnosis the problem is more complicated.
How do you fix a VVT system?
How does a VVT actuator work? Basically, it varies the valve timing by shifting the phase angle of camshafts. For example, at high speed, the inlet camshaft will be rotated in advance by 30° so to enable earlier intake. This movement is controlled by engine management system according to need, and actuated by hydraulic valve gears.
Is VVT worth keeping?
As for keeping or deleting VVT, the benefit of keeping VVT is that you gain low end torque. The drawback is that you lose high end hp compared to a LS3 cam. Many people swear up and down that a VVT cam is the way to go, while others swear up and down to delete VVT and do a LS3 conversion.
How do I know if my VVT is working? Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load.
Can you cam a VVT engine?
But street engines are expected to deliver excellent power and throttle manners between idle and 7,000 rpm. This is where VVT really shines. VVT is all about advancing or retarding the camshaft.

What RPM does VVT kick in?
When the engine is operating below 6000 rpm, the low lobe is operating the rocker arm and thus the valves. When the engine is operating above 6000 rpm, the ECU activates an oil pressure switch which pushes a sliding pin under the slipper follower on each rocker arm.
Will VVT solenoid cause knocking? A bad or faulty connected VVT solenoid can and often does cause engine knocking, inconsistent idle and acceleration problems. The issue could be with the solenoid itself or the electrical harness connected to the VVT.
When I press on the gas I hear a rattling noise?
You usually hear this noise when accelerating the vehicle. Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
How do you check a VVT solenoid?
How do you clean a VVT solenoid?
How much is a solenoid replacement?
Shift Solenoid Repair and Replacement Cost
The overall cost to replace the shift solenoid in an automatic transmission ranges from $200 to $500 for a single solenoid. If the damage requires you to replace the entire solenoid pack the cost increases to between $250 and $700.
Where is VVT solenoid located? The variable valve timing solenoid is located at the front of the engine, typically near the front of the valve cover.
Where is the intake camshaft position actuator solenoid?
Product Description. Camshaft Position Actuator Solenoid are located on the cylinder head of your Chevrolet or GM vehicle control the position of the camshafts.
What causes P1349? The code, P1349 is triggered when the valve timing isn’t changing from the current valve timing state, or when the valve timing is fixed. Possible causes of trouble code P1349 include: Low or dirty engine oil. Incorrect valve timing.
Where is the variable valve timing solenoid located?
The variable valve timing solenoid is located at the front of the engine, typically near the front of the valve cover.
What is code P0011? P0011 is the OBD-II generic code indicating the engine control module (ECM) has determined that the bank 1 intake camshaft is more advanced than what the ECM has commanded it be. This over-advanced condition could be during advancing or retarding of the camshaft timing.
