What the P0470 code means. 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.
What is a P0470 code mean?
Exhaust Pressure Sensor Malfunction
Exhaust Pressure Sensor “A” Circuit. What does OBD-II fault code P0470 mean? Code P0470 stands for Exhaust Pressure Sensor Malfunction. Some vehicles (mainly those with turbocharged engines) have an exhaust pressure sensor (EP). This sensor does exactly what the name implies – it measures exhaust backpressure.
Where is the exhaust pressure sensor located?
Usually, you’ll find the sensor bolted onto the side or bottom of the engine, or along the firewall in the back of the engine well.
How do you fix P0471?
A good starting point for resolving a P0471 code is to disconnect the tube that connects the pressure sensor to the exhaust manifold. Inspect the tube for any blockages. You may need to blow through the tube to see if air can pass easily through.
How do you clean exhaust pressure sensors?
Zitat von Youtube: So the way I've seen has been a little bit easier is put a little pad down put your knee on top where the jack. Parts are it makes a little bit easier to get to it. But.
What causes code P0470?
What the P0470 code means. 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.
What does a exhaust back pressure sensor do?
The Exhaust Gas Pressure Sensor or Exhaust Back Pressure Sensor (EBP) is a key component in the Diesel Particulate Filter (DPF) regeneration process. The DPF traps Particulate Matter (PM) and soot, preventing it from harming the environment.
