OBD reader showing 3 faults on internal pressure sensor for cylinder 3, 2, and 1. We replaced all 4 glow plugs with bosch glow plugs and still showing error code. Could it be a sensor?

There are just too many to list....
Pull up the data blocks for cylinder pressure and with the engine idling wiggle the connectors and see if you get a change. You may need new connector harnesses spliced in. There is a TSB about this.

Thank you. Will look into this. We also got the j519 code along with glow plugs and my battery only lasts 2 years before needing replaced. Is it all related?

My 2011 w/75k has been setting a CEL. Only once out of 5 x's my generic obdII reader pulled any codes before clearing(P13ce, P13do).

Do you by chance have the TSB#? I'll be making a dealership stop soon.

BTW your experience is always appreciated, thx
