2003 Honda Accord 2.4L P2646 Code: Rocker Arm Actuator System Performance/Stuck Off Bank 1 Diagnosis

Model: 2003 Accord Fault Code: P2646 Posted: 2019-12-04 18:41

I'm currently experiencing a P2646 diagnostic code on my 2003 Honda Accord 2.4L, which indicates an issue with the rocker arm actuator system performance or stuck-off condition on Bank 1. The vehicle exhibits noticeable bucking at around 2500 RPM. While this fault code typically points to a malfunctioning solenoid unit, my granddaughter mentioned that a local tire shop recently replaced the solenoid. I'm now questioning whether this repair was truly effective or if there's another underlying cause. Could this be a false positive or an incomplete fix? Any insights from owners of similar models would be greatly appreciated.
