Code P1113 Pontiac Description

Multi-Ram system uses variable air induction tuning to achieve maximum performance and efficiency over the entire operating range of the engine. The system consists of 2 main components. The intake manifold contains an intake plenum Switchover Valve. This vacuum-operated valve is essentially a moveable divider that changes the airflow characteristics of the intake manifold. Vacuum to the valve is controlled by an Engine Control Module (ECM) controlled solenoid valve.
The intake resonance Switchover Valve is located in the air intake duct assembly in front of the engine. This vacuum-operated valve is also a moveable divider that changes the tuning of the air intake system. Vacuum to the valve is controlled by ECM controlled solenoid valve. By opening and closing these valves independently in different combinations, 4 different airflow configurations can be created, each optimized to a particular set of engine operating conditions.
Both solenoid valves are supplied power via the main relay (switched battery feed circuit). Both solenoid valves have a control circuit to ECM. ECM controls a valve by grounding the control circuit via an internal driver. The primary function of the driver is to supply ground for components being controlled. Each driver has a fault line which is monitored by ECM. When ECM is commanding a component on, control circuit voltage should be low (near zero volts). When ECM is commanding the control circuit to a component off, circuit voltage should be high (near battery voltage). If the fault detection circuit senses a voltage other than what is expected, this Diagnostic Trouble Code (DTC) will set.
ECM will monitor the circuit for short to ground, short to voltage, open or an internally shorted or excessively low resistance in the circuit. When ECM detects any of these malfunctions, this DTC will set, and the affected driver will be disabled. ECM will continue to test the circuit and if the fault disappears, the driver will be reactivated.
