P245B Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
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.
