P047C OBD-II: Exhaust Pressure Sensor "B" Circuit Low
P047C Severity
Moderate
Will P047C 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 P047C?
The Exhaust Pressure Sensor tells the engine control module (PCM) how much pressure is in the exhaust manifold. If the PCM determines there is an incorrect signal from the Exhaust Pressure Sensor, the PCM will set code P047C.
