CID 0275 FMI 04 Right Turbo Inlet Pressure short to ground
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects all of the following conditions:
- The ECM reads signal voltage that is below 1.72 VDC for one second.
- 262-03 diagnostic code is not active.
- 262-04 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 inlet pressure as invalid data and a default value of 45 kPa (6.5 psi) is used.
- Low power
Test Step 1. Perform the following diagnostic procedure: Engine Sensor Open/Short Circuit - Test
Results:
- OK - STOP
