EGR monitor
Posted: Wed Apr 17, 2019 7:11 pm
Hi guys
Just want to confirm i am reading the outputs correctly for the following Air and EGR operations.
I have been monitoring:
EGR_EGT_TEMP which as others show max at 215 and is just used to trigger EGR operation
EGRVPB1 which should be % of EGR valve operation, can be seen oeprating constantly. On full throttle and DPF burn it is closed
EGR_A_CMD which looks to be the instruction to operate the valve above as valves match
ACT - I am wanting confirmation of probe location was hoping this was in the intake manifold
IAT - I am wanting confirmation of probe location was hoping this is at the intercooler outlet, although it reads similair to ambient temp and i doubt the intercooler is that efficient.
any help would be appreciated to understand this control better
