Does anyone know which MAP sensor “B” I have circled in purple is? Is it the one on the intake horn? I’m assuming the “A” is just after the MAF on the intake? Assuming “B” is a readable parameter, it should be reading something right? I’m having soot based regens every day over the past couple of days, makes no difference, TT in tow or not. Started when I did my recent LOF on my truck. Noticed MAP “B” was not reading. Everything else seems normal, I just cleaned the MAF and both MAP sensors just in case. Driving habits are the same and the air filter I’m using is the Fleetguard from Geno’s. Could that sensor not reading cause my soot load to jump up and not achieve a passive regen?
