My truck has thrown codes 522 air management circut 1 failure.
And, 332 insufficient egr flow detected.
Im sure that if I clean out the egr that it will clear that code. But would the one connect the other? Or does someone have an answer to the air management code?
There doesnt seem to be a loss of performance but I wouldnt know, as the codes where there when i bought the truck
