Demandated isx2350 SPN 108 FMI 2 indicated one of the pressure sensors just not sure which one. What one should I start with?
isn't that a fault for the barro sensor intermittent signal?. -- cummins Fault code 295?.
bad barro sensor or wiring to it?
I know that it checks it against the exhaust manifold pressure sensor before engine start.... so you should ensure that sensor is fairly new and its feed-circuit thru the thermostat housing is not blocked up too.
