P049C OBD-II: Exhaust Gas Recirculation "B" Flow Excessive Detected
P049C Severity
Moderate
Will P049C go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P049C?
EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions. If the engine control module (PCM) does not detect the amount of flow requested from the EGR, it will set code P049C.
