Cummins ISX CM870 (2003-06) Fault Code: 295 PID: P108 SPN: 108 FMI: 2/2 Barometric Pressure – Data Erratic, Intermittent, or Incorrect. An error in the barometric pressure sensor signal was detected by the ECM.
At key-on, before the engine starts, the sensor readings for intake manifold pressure, exhaust gas pressure, and engine oil pressure are compared with the barometric pressure. This fault code occurs if the barometric pressure sensor reading is different from any two of the other three. This check is only done once after the keyswitch is turned on and before the engine is started. The engine oil temperature must also be at least 7?C [45?F] for this check to run.
Shop exhaust fans can cause this fault code to come active. Turn exhaust fans off when troubleshooting this fault code.
Possible repair:
1)Replace the barometric pressure sensor.
