CAP-BEARING 4T5255 - Caterpillar

CID 1785 FMI 10Conditions Which Generate This Code:This diagnostic code is designed to detect the loss of the 5 Volt DC supply at the sensor connector.The Electronic Control Module (ECM) detects the following conditions:
The engine speed is more than 1000 rpm.
The intake manifold pressure is within the acceptable range.
No 0262 codes for the 5 Volt supply are active.
Diagnostic code 0168-01 is not active.System Response:The warning light on the control panel will flash. The ECM will log the diagnostic code. The ECM will flag the intake manifold pressure as being invalid. A default value is used for the intake manifold pressure.For engines with an electronically controlled wastegate, the signal for the wastegate solenoid will be set to a default value while this code is active. This will cause the engine to have poor acceleration but the default setting will prevent any overpressure in the intake manifold which could be caused by an overspeed of the turbocharger.Note: Any open circuits or short circuits in the signal wire for the oil pressure may reset this diagnostic.Possible Performance Effect:
The engine will be derated.Troubleshooting:This diagnostic code detects the loss of the 5 Volt DC supply to the sensor.Test Step 1. Perform the following diagnostic procedure: "Engine Pressure Sensor Open or Short Circuit - Test"Results:
OK - STOP
