Code P1376 Buick Description

The Powertrain Control Module (PCM) applies 2.5 volts on the Reference Low (Ref Lo) Voltage circuit to the Ignition Control Module. Reference Low Voltage to the Powertrain Control Module represents the voltage difference between Reference Low and the Powertrain Control Module power ground. This is needed to ensure that the Powertrain Control Module and Ignition Control (IC) Module signals all have the same ground reference. The Diagnostic Trouble Code (DTC) will be set when the Reference Low Voltage to the Powertrain Control Module is too low.
