CID 0273 FMI 00 Turbo Outlet Pressure above normal
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the following conditions:
- The outlet pressure of the turbocharger is greater than
200 kPa (29 psi) . - The engine speed is within 50 rpm of low idle for five seconds.
- 262-03 diagnostic code is not active.
- 262-04 diagnostic code is not active.
- 273-03 diagnostic code is not active.
- 273-04 diagnostic code is not active.
- 273-13 diagnostic code is not active.
- The ECM has been powered for at least three seconds.
System Response:
The ECM will log the diagnostic code. The diagnostic code may be viewed on a display module or on the Caterpillar Electronic Technician (ET). The ECM flags turbocharger compressor outlet pressure as invalid data and a default value of
Possible Performance Effect:
- Low power
Troubleshooting:
The turbocharger outlet pressure sensor is not producing a valid signal.
Test Step 1.
- Replace the turbocharger outlet pressure sensor.
- Verify that the repair eliminates the problem.
Results:
- OK - STOP
