Hi my name is***** will be glad to help. Let me know what engine make and model this is. If you have the Cummins here is the code information.

SPN: 1079
FMI: 4/4
LAMP: Amber
Sensor Supply Voltage Number 1 Circuit - shorted low. Low voltage detected at sensor supply Number 1 circuit.
Engine will run derated.
Circuit Description
The sensor supply voltage Number 1 of the electronic control module (ECM) provides (+) 5 volt supply for the barometric pressure sensor, engine oil pressure sensor, and fuel pump pressure sensor on the engine harness. This +5 volt supply also powers two optional OEM devices. The two devices are digital vehicle speed sensor and remote accelerator sensor.
Component Location
The sensor supply Number 1 is located in the ECM. The supply voltage is spliced off in the engine and OEM harness to each sensor it supports.
Shop Talk
Low voltage on the (+) 5 volt supply line can be caused by a short circuit to ground in a supply line, a short circuit between a supply line and a return line, a failed sensor, or a failed ECM power supply.
