N14 barometric pressure fault (celect plus) PID-108

PID-108 Barometric Pressure

I changed to new sensor yesterday 203.00 for sensor and harness. This didnt fix the issue. The sensor was located at rear of the engine behind the ECM seems to go into the block the new sensor is zip tied to the harness. Truck runs fine on flat ground but struggles up a hill. At first the fault was intermittent after changing the sensor its now constant. Is there something else that could cause this fault? Im not showing any other faults. I changed the engine harness about 18month ago.

 

Truck will be here tomorrow Ill start looking into the wiring only thing not changed was power to ecm, ecm has been changed too.
