    i have codes p0452 ,p0405, and p0160 and ive change a few things already like o2 senor b2s2  , cleaned egr valve . but im a contractor by trade and just with my experience all the codes seems to be related to a electical issues and on the same letter curcuit like sensor A is low for egr valve and switch A for the evap system and so im honestly lost because today i ran a few test and checked fuses and wires and i found 3 fuses without power (ENG-I ECM-I and IGN-E) i did have the car off if that means anything but also no fuses on the inside fuse box lit up ….when i first got the van a few weeks ago it started as if the battery was low during my test today i cleaned battery terminals and now i have more power than before but i can hear the starter is bad now ..any info would help

    Did you measure the voltage on the battery? Maybe the low voltage from the bad battery is causing all issues. Worth checking properly before replacing any parts!
