C15 – 0108-03 Barometric Pressure voltage high (26)

Conditions Which Generate This Code:

The Engine Control Module (ECM) detects the following conditions:
• The signal voltage from the atmospheric pressure sensor is greater than 4.95 VDC for more than 30 seconds.
• The ECM has been powered for at least two seconds.

System Response:
The ECM will log the diagnostic code and the ECM will trigger a snapshot. The check engine lamp will
illuminate while this diagnostic code is active. The ECM will default to 100 kPa (15 psi) for atmospheric pressure.

Possible Performance Effect:
The engine power will be derated by 10%.

Troubleshooting:
Perform the following diagnostic procedure: “Engine Pressure Sensor Open or Short Circuit – Test”

Results:
• OK – STOP.
