Table 1
Diagnostic Codes Table
Code and Description Conditions which Generate this Code System Response
41-3 8 Volt DC Supply voltage above normal The digital sensor supply voltage is above normal for one second.
The Electronic Control Module (ECM) has been powered for three seconds. The code is logged.
All sensors are set to default values.
41-4 8 Volt DC Supply voltage below normal The digital sensor supply voltage is below normal for one second.
The ECM has been powered for three seconds.
100-10 Engine Oil Pressure Sensor abnormal rate of change The signal voltage has not changed at a normal rate for thirty seconds.
Engine speed must be above 600 rpm. The code is logged.
All sensors are set to default values.
262-3 5 Volt Sensor DC Power Supply voltage above normal The analog sensor supply voltage is above normal for one second.
The ECM has been powered for three seconds. The code is logged.
All sensors are set to default values.
262-4 5 Volt Sensor DC Power Supply voltage below normal The analog sensor supply voltage is below normal for one second.
The ECM has been powered for three seconds.
1785-10 Intake Manifold Pressure Sensor abnormal rate of change The analog sensor supply voltage is missing from the sensor. The code is logged.
All sensors are set to default values. System OperationThe ECM supplies a regulated voltage of 5.0 0.2 VDC to the following sensors:
Fuel pressure sensor
Engine oil pressure sensor
Injection actuation pressure sensor
Atmospheric pressure sensor
Intake manifold pressure sensor
Auxiliary pressure sensorThe ECM supplies a regulated voltage of 8.0 0.4 VDC to the coolant level sensor.The supply voltage for the sensors is routed from the ECM to terminal A of each sensor connector. The sensor return for the sensors is routed from the ECM to terminal B of each sensor connector. The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.If a 10 code is logged, this indicates that the 5 volt supply is not available at the sensor connector. During normal engine operation, each of the signals from the pressure sensors fluctuate slightly. When the 5 volt supply becomes unavailable at the pressure sensor connector, the signal from that sensor floats to a midrange value. The signal will not fluctuate. If the signal from the sensor remains abnormally steady for more than 30 seconds, the ECM will activate this code.Note: The sensors are not protected from overvoltage. A short from the supply line to the +Battery may damage the sensors. If any of the 3 diagnostic codes are active, it is possible that a sensor has been damaged. Repair the sensor supply and check for any active sensor diagnostic codes in order to determine if a sensor has failed.

Schematic for the sensor supply circuit
The connection of any electrical equipment and the disconnection of any electrical equipment may cause an explosion hazard which may result in injury or death. Do not connect any electrical equipment or disconnect any electrical equipment in an explosive atmosphere.
Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove electrical power from the ECM.

Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors that are associated with the circuit.
Check the allen head screw for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and wiring for abrasion and for pinch points from the sensors back to the ECM. Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and connectors appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem with the connectors and/or wiring.Repair:
