P1112 SATURN Meaning

The Intake Air Temperature (IAT) sensor contains a semiconductor device that changes resistance based on temperature (a thermistor). The IAT sensor is mounted in the air intake passage of the engine’s air intake system. The IAT sensor has a signal circuit and a ground circuit. The PCM applies a voltage (approximately 5.0 volts) to the sensor signal circuit. The PCM monitors changes in this voltage caused by changes in the sensor’s resistance to determine the intake air temperature.

When the intake air is cold, the sensor resistance (thermistor) is high and the PCM signal voltage is only slightly lowered across the sensor to ground. The PCM detects a high signal voltage (low temperature). When the intake air is hot, the sensor resistance is low and the signal voltage is lowered further. This causes the PCM to detect a low signal voltage (high temperature).

P1112 SUBARU Meaning

The intake air temperature (IAT) sensor is integrated into the mass air flow sensor or in some vehicles mounted on the air filter housing. The sensor detects intake air temperature and sends a signal to the engine control module (ECM). The temperature sensing unit uses a thermistor that is sensitive to temperature changes. The electrical resistance of the thermistor decreases in response to increasing temperature. The intake air temperature signal is used as input for various vehicle systems.

P1113 Meaning

The Multi-Ram system uses variable intake air tuning to achieve maximum performance and efficiency across the entire engine operating range. The system consists of 2 main components. The intake manifold contains an intake plenum switching valve. This vacuum-operated valve is essentially a movable divider that changes the airflow characteristics of the intake manifold. The vacuum to the valve is controlled by a solenoid valve operated by the Engine Control Module (ECM).

The intake resonance switching valve is located in the air intake duct in front of the engine. This vacuum-operated valve is also a movable divider that changes the tuning of the air intake system. The vacuum to the valve is controlled by an ECM-controlled solenoid valve. By opening and closing these valves independently in different combinations, 4 different airflow configurations can be created, each optimized for a particular set of engine operating conditions.

Both solenoid valves are powered via the main relay (switched battery power circuit). Both solenoid valves have a control circuit to the ECM. The ECM controls a valve by grounding the control circuit through an internal driver. The main function of the driver is to provide ground for controlled components. Each driver has a fault line that is monitored by the ECM. When the ECM commands a component to turn on, the control circuit voltage should be low (near zero volts). When the ECM commands the control circuit to a component off, the circuit voltage should be high (near battery voltage). If the fault detection circuit detects a voltage other than expected, this Diagnostic Trouble Code (DTC) will be set.

The ECM will monitor the circuit for a short to ground, short to voltage, open circuit resistance, or an internal short or excessively low resistance in the circuit. When the ECM detects any of these malfunctions, this DTC is set and the affected driver is disabled. The ECM will continue to test the circuit and if the fault disappears, the driver will be reactivated.
