What does p0476 mean on exhaust pressure sensor?
What does p0476 mean on exhaust pressure sensor?
If all tests have passed so far, and you continue to get a P0476 code, this would most likely indicate a failed Exhaust Pressure sensor, although a failed PCM could not be ruled out until the sensor had been replaced.
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.
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 p0470 backpressure sensor malfunction?
Some common causes of code P0470 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors in the backpressure sensors’ reference and/or signal circuits Boost pressure leaks on applications where this sensor is used for boost pressure control
What is the purpose of the exhaust pressure control valve?
This heat and/or back pressure can be used to assist in cold start warm up. It can also be used to oppose cylinder pressure coming from the engine cylinders out of the exhaust, thereby slowing the engine down and the vehicle along with it. This is especially useful during towing operations.
How much psi to change exhaust pressure control valve?
After that start the engine, drive the vehicle at a safe speed, and then momentarily accelerate the engine to wide open throttle, insuring engine RPM does not exceed 2500-3000 RPMs. You should note a change of at least 18 PSI, possibly more depending upon the vehicle manufacturer and year the vehicle was made.
