P2495 GMC Code - Exhaust Gas Recirculation Cooler Bypass Position Sensor Circuit High Voltage
Quick Answer
The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) cooler bypass valve position sensor to determine the position of the bypass valve. Common causes include Faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve, Exhaust Gas Recirculation Cooler Bypass Valve harness is open or shorted, Exhaust Gas Recirculation Cooler Bypass Valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
