P1A76 CHEVROLET – Starter/Generator Control Module Coolant Temperature Sensor 2 Circuit Low Voltage

P1A76 CHEVROLET Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1A76 CHEVROLET Possible Causes

Faulty Starter/Generator Control Module (SGCM),Starter/Generator Control Module (SGCM) harness is open or shorted,Starter/Generator Control Module (SGCM) circuit poor electrical connection

P1A76 CHEVROLET Description

The Starter/Generator Control Module (SGCM) monitors its internal fluid temperature sensors to control the SGCM coolant pump and SGCM cooling fan. The internal fluid temperature sensors of the SGCM are thermistors and are not serviceable. When the internal fluid temperatures are cold, the resistances of the sensors are high and the voltage signals are high. When the internal fluid temperatures are hot, the resistances of the sensors are low and the voltage signals are low. The input parameters are not displayed on the scan tool.
