Exhaust Back Pressure Sensor Circuit Malfunction and Manifold Intake Air Heater


what do they mean??

Usually when you get an EBP sensor malfunction that could me one of two things or both, 1) the EBP sensor is not working, 2) The tube that connects from the front of the passenger side exhaust manifold to the EBP could be clogged (very common). When this code pops up usually it is suggested to put a new EBP sensor in and clean the tube or replace with the tube with a new one. The EBP sensor is located directly infront of HPOP reservoir. I did this replacement about 4 months ago. Cheapest place on these parts will be Powerstrokeshop.com

I'm not 100 percent sure on the AIH code, but I would guess it would be either the AIH relay is bad, or the AIH is bad it self.

Here is a right up on the EBP sensor replacement.

Here is guzzles code list too, a little more comprehensive and a little more explained.
