Exhaust Gas Recirculation "B" Control Circuit High

The EGR B control circuit voltage is too high, usually caused by a wiring open circuit, bad connector, or failed solenoid. The engine cannot properly manage exhaust recirculation without this control signal, leading to increased emissions and poor performance. Professional diagnostic work is needed to locate and repair the electrical or solenoid fault.
