2005 DT466 With EGR

Active Codes
143 Incorrect CMP signal signature
145 CMp signal inactive
146 CKP signal inactive
147 Incorrect CKP signal

Initially the bus would not start.
Replaced the Cam and crank sensor and the bus ran fine for a day and would not start again.
We then replaced the harness and the bus ran fine for a few months.
Now the problem is back.
Does anyone have any ideas?

Get your voltmeter out and check refrence voltages at the sensors, and grounds. I don't know if this is a circuit that shares these voltages out of ECM or not, but very well possible.
