P0470 is a code that means the sensor in charge of assessing exhaust pressure isn’t working properly.
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 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 does 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.
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.
How do you change a DPF pressure sensor?
Zitat von Youtube: And then unclip it and the sensor just pulls out a little bit of wiggling. If it's been in there a few years but pretty straightforward. And this is what the sensor looks like.
How do you check exhaust pressure sensor?
Using a pressure gauge, measure the pressure of both hoses. For sufficient accuracy, use an exhaust back pressure gauge that measures 0-15 PSI. Check the signal voltage again. The voltage should read a number between the pressure values of the hoses.
How much does it cost to replace a DPF sensor?
The cost of a diesel particulate filter replacement can vary greatly depending on engine power and vehicle make. However, the average DPF replacement cost is around £1,000-£2,000 in the UK. However, the usual price range can be between £750-£3,000.
