CID 0274 FMI 13 Atmospheric Pressure calibration required
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects one of the following conditions:
- The atmospheric pressure sensor has never calibrated or a manual calibration has failed.
- Atmospheric pressure is less than
45 kPa (6.5 psi) . - Atmospheric pressure is greater than
111 kPa (16 psi) . - Atmospheric pressure fluctuates more than
5 kPa (0.75 psi) during a calibration attempt.
System Response:
The ECM will not log the diagnostic code. The diagnostic code may be viewed on a display module or on the Caterpillar Electronic Technician (ET) while the code is active.
Possible Performance Effect:
- Low power
Troubleshooting:
Test Step 1. Perform the following diagnostic procedure: "Engine Pressure Sensor - Calibrate"
Results:
- OK - STOP
