MOUNT AS 4862509 - Caterpillar

The Electronic Control Module (ECM) detects the following conditions:
No other codes for the oil pressure sensor are active.
No 0262 diagnostic codes are active for the 5 Volt supply.
The engine speed is greater than 600 rpm.
The engine oil pressure signal is within the limits of 410 kPa (59 psi) to 520 kPa (75 psi) with a pressure variation of less than 1.68 kPa (0.25 psi)for more than 30 seconds.
The engine oil pressure signal remains constant for 30 seconds.System Response:A warning will appear on the display on the control panel.The ECM will log the diagnostic code. The diagnostic code can be viewed on the electronic service tool.The ECM will flag the engine oil pressure as invalid data.The data for engine oil pressure is set to a default value of 500 kPa (72 psi).The electronic service tool will display "Conditions Not Met" on the status screen.Possible Performance Effect:NoneTroubleshooting:This diagnostic code is designed to detect the loss of the 5 Volt supply to the sensor.Test Step 1. Perform the following diagnostic procedure: "Engine Pressure Sensor Open or Short Circuit - Test"Results:
OK - STOP
