P1115 Meaning

The IAT sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as temperature increases and resistance increases as temperature decreases. The variable resistance affects the voltage drop across the sensor terminals and provides electrical signals to the Powertrain Control Module (PCM) corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that the change in the passive sensor’s resistance causes a change in the total current flow. The voltage that drops across a fixed resistor in series with the sensor resistance determines the voltage signal to the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.

The IAT sensor provides air temperature information to the PCM. The PCM uses air temperature information as a correction factor in calculating fuel, spark, and airflow.

The IAT sensor provides faster response time to temperature change than the ECT or CHT sensor.
Currently, there are 2 types of IAT sensors used, a standalone, non-integrated type and an integrated type. Both types work the same way, but the integrated type is incorporated into the Mass Air Flow (MAF) sensor instead of being a standalone sensor.

P1115 TOYOTA PRIUS Meaning

This system uses an electric pump to supply hot coolant stored in the coolant heat storage tank to the engine cylinder head, in order to optimize engine start-up combustion and reduce the amount of unburned gas discharged during engine starting. Before engine starting, the ECM operates the electric water pump to direct hot coolant from the heat storage tank into the engine, to heat the cylinder head (this process is called “preheat mode”). The electric water pump’s operating duration varies depending on the cylinder head temperature. During normal engine operation, the water valve opens the passage between the cylinder head and the heater and closes the passage between the cylinder head and the tank. During preheat mode when the cylinder head is being heated, the water valve opens the passage between the tank and the cylinder head, allowing coolant to flow from the tank to the cylinder head. At this time, to quickly warm the intake port before engine starting, the coolant flows in the reverse direction.

P1115 BUICK Meaning

The Engine Coolant Temperature (ECT) sensor contains a semiconductor device that changes resistance based on temperature (a thermistor). The ECT sensor is mounted in the left bank cylinder head near the front of the engine. The ECT 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 engine coolant temperature.

When the engine coolant 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 engine coolant 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).
