What are the causes of Honda Accord VSA solenoid valve failure?

[AbigailLynn]

Honda Accord VSA solenoid valve failure has the following causes: Difficulty starting: The Honda Accord experiences difficulty starting, unstable idling, and shaking during acceleration, with more severe symptoms when the engine is cold. This is mostly caused by an excessively dirty throttle body or severe carbon buildup in the idle control valve. The engine malfunction indicator light may sometimes stay on. Restricted air intake: The main issue lies in restricted air intake. During cold starts, the air intake is relatively higher, and although the computer will adjust the idle control valve to compensate, this process takes time. Therefore, such failures often occur due to an excessively dirty throttle body or severe carbon buildup in the idle control valve. However, this type of failure rarely causes the malfunction indicator light to stay on.
