RENR5042-02 87 Troubleshooting Section Diagnostic Functional Tests i02289813 5 Volt Engine Pressure Sensor Supply Circuit - Test SMCS Code: 5574-038 System Operation Description: The Electronic Control Module (ECM) creates a regulated voltage of 5.0 ± 0.2 VDC that is supplied to terminal A of the harness connectors for these sensors: Injection actuation pressure sensor Boost pressure sensor Atmospheric pressure sensor Fuel pressure sensor Engine oil pressure sensor Auxiliary pressure sensor (if equipped) This procedure covers the following diagnostic codes:
262-03 5 Volt Sensor DC Power Supply short to +batt 262-04 5 Volt Sensor DC Power Supply short to ground 100-10 Engine Oil Pressure Sensor abnormal rate of change 102-10 Boost Pressure Sensor abnormal rate of change A +5 V diagnostic code is probably caused by a short circuit to ground or a short circuit to another voltage source in the harness. The next likely cause is a problem with a sensor. The least likely cause is a problem with the ECM.
