I had a bad ICP Sensor. While installing the new ICP Sensor, I decided to also install a new EBP Sensor even though I was not throwing a code. Changing the EBP Sensor, I noted the tube was showing fatigue and decided to replace it as well. After installing the new EBP Sensor and tube, I now have a P0470 code (Exhaust Back Pressure Circuit Failure). I was very careful with the plug and it looks great. My engine monitor shows a constant 43 psi of Back Pressure never fluctuating. Does anyone know if the PCM will reflect a 43 psi reading as a default if I indeed have a bad circuit? Thank you, Bob
So with a normal load in the truck or van and running around 1700 rpms the back pressure should be around 18-20?
