What is P0471 code?
What is P0471 code?
If the P0471 code appears, it means that the powertrain control module has detected that there is a voltage reading from the exhaust system back pressure sensor circuit that is out of the normal range. This is generally monitored in turbocharged vehicles, and those vehicles that have diesel engines.
What are the symptoms of a p0470 engine code?
P0474 Exhaust Pressure Sensor “A” Circuit Intermittent Symptoms of a P0470 engine code may include: Unable to perform manual regeneration – burn off the soot out of the particulate filter. Looks like a catalytic converter but has temp sensors and pressure sensor probes inserted into it.
When do I get the error code p0470 on my VW?
That’s not to say you wouldn’t necessarily get this code in a VW or other make though. Error Code P0470 happens when the sensor in charge of determining the exhaust pressure is not working properly.
What does it mean when your exhaust pressure sensor says p0471?
This code means that the signal being provided by the exhaust pressure sensor isn’t matching the ambient air pressure or manifold pressure. It’s associated with code P0471. The only difference between the two is how long the problem has persisted for the electrical/mechanical problem the vehicle is having.
What’s the difference between p0470 and P0 471?
This can be an electrical circuit fault or it can be mechanical. Code P0471 may also be present at the same time as the P0470. The only difference between these 2 codes is how long the problem lasts and the type of electrical / mechanical problem that the sensor / circuit / engine controller is having.

What causes a check engine light with a P0420 code?
In most cases, a P0420 code is caused by a bad catalytic converter. You will probably not have any symptoms except the check engine light with just the P0420 code stored. You may have other problems with your engine damaging the catalytic converter, which can cause symptoms like rough idle, rough acceleration, misfires, and hard shifting.
