G3516B Engines Caterpillar

The voltage supply from the Electronic Control Module (ECM) to one of the following sensors is below the normal range.

• Detonation sensors

• Sensor for inlet air pressure

• Sensor for engine coolant pressure

System Response:

Default values are assumed for the inputs to the ECM from all of the 8 volt analog sensors. All of the diagnostic codes for the 8 volt analog sensors to the ECM are disabled while this code is active.

The fuel is shut off. The shutdown output is activated. The code is logged.

Possible Performance Effect:

Since the engine protection is disabled,the engine is shut down.

Troubleshooting:

Test Step 1. Perform the following diagnostic procedure: "+8V Sensor Voltage Supply"

Results:

• OK - STOP
