SEAL-O-RING 5F0149 - Caterpillar

MID 036 CID 0262 FMI 03Conditions Which Generate This Code:The supply voltage from the Electronic Control Module (ECM) to the sensors for the following parameters is exceeding the normal level:
Inlet air temperature
Engine oil temperature
Filtered engine oil pressure
Unfiltered engine oil pressureIf the engine is equipped with a desired speed potentiometer, a short circuit in the signal wire for the desired speed potentiometer can generate this code.System Response:All of the inputs to the ECM for the 5 volt analog sensors assume default values. All other diagnostic codes for the 5 volt analog sensors are disabled while this diagnostic code is active. The "Status" screen of Caterpillar Electronic Technician (ET) indicates a "Sensor Supply Fault" for each sensor. This indicates that the sensors are not operating due to an active diagnostic code.The shutdown indicator is activated. The code is logged.Possible Performance Effect:Since engine protection is disabled, the engine is shut down.Troubleshooting:Test Step 1. Perform the following diagnostic procedure: "+5V Sensor Voltage Supply"Results:
OK - STOP
