Honda Civic P2821 Error: Is Transmission Pressure Switch A the Same as Pressure Line Solenoid A?

Model: Honda Civic Fault Code: P2821 Posted: 2022-01-09 19:14

I'm experiencing Honda Civic transmission code P2821 and want to confirm whether the transmission pressure switch A is identical to the pressure line solenoid A. Can anyone clarify this? Additionally, I'd like to know how costly a replacement for either component might be. Thanks for any insights.
