How does variable valve timing control system work?
P1009 Honda Description. The variable valve timing control (VTC) system controls the phase of the intake camshaft. It uses oil pressure to operate the VTC actuator so the valve timing is optimized depending on driving conditions.
When did Honda start using variable timing system?
When Honda started tinkering with VTEC in the early 1980s, it sparked an internal-combustion revolution that spread to nearly every brand. The simplest of the resulting variable-timing systems employ cam phasers, or mechanisms that change the relationship between the crankshaft and the camshaft (s).
What does VTEC stand for in Honda valve timing?
VTEC is a type of variable valve-timing system developed and used by Honda. It stands for V ariable Valve T iming & Lift E lectronic C ontrol. Like most other variable-valve timing systems, VTEC…
Where is the variable valve timing solenoid located?
Locating the VVT Solenoid. It is located near the front of the valve cover, i.e. in the front of the engine itself. If you take the new solenoid and try to locate something that looks similar, things will be easier. You will be able to see the connector that lies at the exposed end of the variable valve timing solenoid.
How does Honda variable valve timing system work?
VTEC is a type of variable valve-timing system developed and used by Honda. It stands for V ariable Valve T iming & Lift E lectronic C ontrol. Like most other variable-valve timing systems, VTEC varies oil pressure to shift between different cam profiles.
Why are variable valve timing solenoids so important?
Variable Valve Timing (VVT) solenoids are one of the greatest innovations in the automotive industry. They help combustion engines to increase performance and increase efficiency. Unfortunately, these VVT solenoids can also fail, which can result in some expensive repairs.
What are the symptoms of a bad variable valve timing?
Symptoms of a Bad or Failing Variable Valve Timing (VVT) Solenoid. Cost of Replacing a Bad or Failing Variable Valve Timing (VVT) Solenoid. Common signs of a faulty VVT solenoid include the Check Engine Light coming on, dirty engine oil, rough engine idle, and decreased fuel economy.
Can a variable valve timing control ( VTC ) be replaced?
The variable valve timing control (VTC) actuator is defective. CORRECTIVE ACTION Replace the VTC actuator. This procedure does not require the complete removal of the cam chain and associated parts, so repair time is much shorter.
