P245A Dodge Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit/Open

Quick Answer

The Exhaust Gas Recirculation (EGR) Cooler bypass valve is used to bypass the EGR cooler when the engine is in an active regeneration mode. Common causes include Coolant System, EGR Cooler, Faulty Exhaust Gas Recirculation (EGR) Temperature Sensor. 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.

Code P245A Dodge Description

The Exhaust Gas Recirculation (EGR) Cooler bypass valve is used to bypass the EGR cooler when the engine is in an active regeneration mode. This is to prevent EGR cooler fouling. There are two portions to this diagnostic. At key on the Engine Control Module (ECM) drives the control line low and then high and monitors the correct status response. Throughout engine operation looks for status response voltage to be within 5-8 volts. The EGR Cooler Bypass valve will send a signal between 1.0 and 1.7 volts. When this occurs the ECM logs a fault. The second portion of this diagnostic monitors Exhaust Gas Recirculation temperature. If the EGR Cooler Bypass valve was in bypass mode incorrectly, the exhaust gas recirculation temperatures would exceed a temperature limit; this condition will also trigger the fault. The ECM will light a MIL lamp immediately after this diagnostic runs and fails. The ECM will turn off the MIL lamp after the diagnostic passes in four consecutive drive cycles.
