Circuit DescriptionThe engine control module (ECM) provides a 5 volt supply to the engine oil pressure switch on the sensor supply circuit. The ECM also provides a ground on the switch return circuit. The engine oil pressure switch provides a signal to the ECM on the engine oil pressure switch signal circuit. This switch signal voltage changes, based on the pressure in the oil rifle. The ECM will detect a low signal voltage at operating conditions when the oil pressure may be slightly lower. Component LocationThe engine oil pressure switch is located on the left side of the engine block....

Circuit DescriptionThe coolant temperature sensor is a variable resistor sensor and is used to measure the temperature of the coolant of the engine. The ECM supplies 5 volts to the coolant temperature signal circuit. The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the coolant temperature.The engine coolant temperature value is used by the ECM for the engine protection system and emissions control. Component LocationThe engine coolant temperature sensor is located near the thermostat housing. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position....
