Yet more problems - Check Engine Light

[vanburen]

So this has been a busy spring commissioning. Got the A/C Pump fixed, replaced my port bank with AGMs. Not the STBD check engine light won't go off.

Are there any things I can check or do I need the Cummins ESC computer?

Many thanks in advance, as usual.

Has anyone recently had a computer hooked to the data ports on your engine? I had Cummins out one time and they hooked a laptop to the data ports and forgot to turn one of the data switches off (it's a conterra (sp?) on/off switch next to the port) and it kept the check engine light illuminated.

It was the intake pressure sensor (again) - this time a fatal flaw. Replaced - all is well. I am never lucky enough to have cheap problems where flipping a switch solves them!
