Code P2653 Acura Description

The P2653 diagnostic trouble code for Acura vehicles refers to an issue with the Rocker Arm Oil Control Solenoid 'B' Circuit having low voltage in Bank 1. This solenoid is responsible for controlling the flow of oil to the rocker arms, which are crucial components in the operation of the engine's valves. When the voltage in the circuit drops below the specified range, it can disrupt the proper functioning of the solenoid, leading to various performance issues in the vehicle.
