Honda VVT Solenoid 15811R40A01: Symptoms, Replacement & Sourcing
2026-09-04
The VVT solenoid valve with OE number 15811R40A01 (also written 15811-R40-A01) controls oil flow to the variable valve timing system on Honda Accord, Civic and Acura models. When it fails, the engine typically logs a VVT-related trouble code and loses low-end torque.
Common Failure Symptoms
- Check engine light with VVT / camshaft timing codes (e.g. P2646/P2647 on Honda).
- Rough idle, hesitation, or reduced fuel economy.
- Rattling or ticking from the top of the engine under load.
Fitment
OE 15811R40A01 is used across Honda Accord, Civic and Acura applications. Because VVT solenoids are engine-specific, confirm your exact model, year and engine code before ordering — a small difference in connector or mounting can make the part wrong.
Buying Tips
Electronic parts carry a real field failure rate. Buy from a supplier that confirms the OE cross-reference in writing and stands behind the part with warranty support — that is worth more than a marginally cheaper quote.
