I have a Mazda 6 2016 Touring 2.2 Diesel. Last software update was done when I had my recall done in 03/2020. Yesterday engine light came on and I used my OBD reader and 2 codes came up:
1. P2262 Turbocharger/Supercharger Boost Pressure Not Detected - Mechanical
2. P0471 Exhaust Pressure Sensor Range/Performance

Currently I have Orange capped exhaust pressure sensor(SH02CK5204). I removed and cleaned it there was some carbon build up in the sensor. I did a test drive and engine light came on again with the same codes. Do you think it could be due to a faulty sensor? Is SHY618W00 is the latest version of the sensor and how hard is it to replace myself? Any other suggestions are also welcome. Thanks in advance

I received the same error yesterday, I did clear the code and it has not come back. I didn't notice any difference in the car operation. except it was -9 c cold start yesterday. I hope it will not come back. From what I have read a lot of people have complained about the pressure sensors needed replacement. form diagram I can see there are two exhaust pressure gas sensors. I have marked them in yellow. which sensor was it for you

Same issue on my cx-5 (same engine), and I replaced the part called 13-X83 in the drawing you posted. It's not an identical replacement to the old orange sensor, but rather a modification kit (part no SHY618W00 as previously commented by another user). This is a metal housing sensor as opposed to the old plastic one. It's fairly easy to replace, so long as you have a long pair of pliers to open the clamps. After replacement I reset the codes and all was good.

The part cost me 1185 NOK (ABOUT 110 GBP) as the car is an older model and out warranty (by a few weeks:( )
