P0470 Even after new EBP sensor

Hi there,

Got a 6.0 that keeps putting the check engine light on for P0470, I removed the EBP sensor replaced that and cleaned the tube, The code then went away for around 10 days. I now am getting the code again. Any idea what to check now could it be a faulty sensor? How can I test the sensor?

Regards

Phil

P0470 – Exhaust Pressure Sensor
Typical Monitoring Duration: P0470 –Greater than 5 seconds.

You could have a wiring issue if you had this come back. It is unlikely the new sensor is the issue.

Your best course of action would be to see if you have a plug or wire issue first. If you know the wires are OK, you can test the sensor with shop air with an adapter or even a rubber nub. It is a 5v 50psi pressure sensor, so you can do it on the bench if you had a spare plug and voltage tester. One wire is 5vref the other is ground and the 3rd is gauge related.
