Our automotive experts have put together the following information about the P245B diagnostic trouble code. We've provided the common symptoms that occur when this code is set along with the frequent repairs that address the issues related to the P245B code.

OBD II Fault Code

• OBD II P245B

OBD-II Code Powertrain Control Module (PCM) failure is defined as a Exhaust Gas Recirculation Cooler Bypass Control Circuit

The EGR valve recirculates exhaust gases back through the engine so that any remaining unburned fuel can be burned. The engine computer (PCM) is programmed to bypass the Exhaust Gas Recirculation (EGR) Cooler under certain driving conditions. The PCM monitors the system to ensure that the bypass valve operates as requested. If the EGR bypass valve fails to operate as requested, code P245B is stored.

Common Problems That Trigger the P245B Code

• Damaged EGR cooler assembly
• EGR cooler bypass valve failure
• Powertrain Control Module (PCM) failure
