P045D OBD-II: Exhaust Gas Recirculation "B" Control Circuit High
P045D Severity
Will P045D 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 P045D?
EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions. If the engine control module (PCM) detects the EGR is not operating as requested, it will set code P045D.
