P245D 2015 Chevrolet Silverado Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage

Quick Answer

The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) 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 Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

What it means: P245D 2015 Chevrolet Silverado indicates Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage.
Common causes: 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: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P245D 2015 Chevrolet Silverado Description

The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) bypass valve position sensor to determine the position of the bypass valve. The ECM sends a reference voltage through the 5-volt reference circuit to the position sensor. The ECM provides a voltage return path for the sensor through the low reference circuit. A variable voltage signal, based on the valve position, is sent from the sensor to the ECM through the position sensor signal circuit. The ECM compares the actual bypass valve position with the desired bypass valve position when the valve is commanded open or closed. The EGR cooler bypass valve is controlled by the ECM through the bypass valve motor high control and the low control circuits. The ECM will pulse width modulate the low control circuit to ground when EGR cooler bypass is desired.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the EGR cooler bypass valve control circuits are shorted to voltage for greater than 3 s.
