This is one of the PIDs in MES relating to the 2.3 twin egr model.
Any idea if it is a physical valve (if so where located) or a flag on the ecu, its intention is to prevent recirculation of exhaust gases in the intercooler to make engine warm up easier..
I suppose the question is what does it do, control and how. what decides if its on or off .
and a side question how do you influence it?
