It’s 100% the skid plate that is blocking the airflow. Last year I try to install a push bumper with a deer guard on it and it threw the same code. You cannot put anything in front of that or it’s just not going to get enough airflow. I ended up, taking the bumper off and returning it to the manufacture to my knowledge even though manufacturers claim it’s OK to put it on the diesel, it is not. None of these manufacturers have done any testing to see if their products work on a diesel versus a gasoline engine. Just because it bolts on doesn’t mean it’s going to work .
P026A Charge Air Cooler Inefficient
Fellas: I was pulling a little 5' x 10' trailer last weekend with my 2019 F150 3.0 Powerstroke, and my check engine light came on. Turns out it was the P026A, and with a little research, could mean a few things. I have a Addictive Desert Designs pre-runner bumper with an aluminum skidplate that is literally right in front of the intercooler. Please see attached pictures. Any suggestions as to how to fix this? I could drill a few 'speed' holes in the skidplate to help with the airflow. Any other advice is always welcome. Much appreciated.
