2015 cascadia with dd13, unit had codes for all injectors ‘needle control valve abnormal operation MAX’ spn 651 652 653 and so on. Followed all troubleshooting. Unit has new injectors, new injector harness, new engine harness and new MCM. Codes will sometimes change to the injector harness bank 1 shorted high but changes every time. Unit only acts up when engine is at running temp. Don’t like throwing parts at it but have no other choice. Any help?
