Cm570
I have a cm570 in a CaseIH tractor, got error code 222 for ambient pressure sensor. Changed it, then got error codes for intake manifold pressure and temperature, changed that sensor, but error codes did not disappear. Do I have an ecm issue or wiring problem?

I would unplug harness at ECM , check harness with voltmeter one end” to the other.
Get engine serial # go to Cummins;quickserve.com
Manual for The harness diagram, it’s free and best of luck!

RE: Cm570
Whenever your dealing with an older engine, it is not very often, but sometimes when replacing sensors, the ecm may be required to get a software update to recognize the range of a newer style sensor. It could simply be that the ecm needs a software update.

just something to consider.

Ok, will check into voltages at sensors and if ecm needs an update.

Is correct,I had to update engine harness two years for sensor compatibility issues, Cummins will sell you adapter to use on old harness” but adapter are very expensive. I just went ahead with new main engine harness.
I do run this CM570 on My 02 Freightshaker.
