LAMP-LED 1631879 - Caterpillar

System Operation Description:Use this procedure to troubleshoot the electrical system if a problem is suspected with the circuit for one of the analog sensors. Also, use this procedure if one of the diagnostic codes in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
Description Conditions which Generate this Code System Response
100-3 Engine Oil Pressure Sensor : Voltage Above Normal The Electronic Control Module (ECM) has detected a voltage on the signal wire of the sensor that is greater than 4.95 V for ten seconds. The code is logged.
The amber warning lamp is illuminated.
The service tool displays "Error Indicator" on the status screen for this parameter.

4290-4 Aftertreatment #1 Three Way Catalytic Converter Outlet Gas Temperature : Voltage Below Normal The ECM has detected a voltage on the signal wire of the sensor that is less than 0.2 V for five seconds. The following analog sensors are used by this engine:
Engine oil pressure sensor
Intake manifold pressure sensor
Temperature sensor at the inlet of the catalytic converter
Temperature sensor at the outlet of the catalytic converterBackground InformationThe ECM continuously creates a pull-up voltage on the signal wire for each sensor. The ECM uses this pull-up voltage in order to detect a problem in the signal circuit. When the ECM detects voltage that is above a threshold on
