1. DTC Descriptor:
DTC
P0112
Intake Air Temperature Pressure Sensor Circuit Low Voltage
DTC
P0113
Intake Air Temperature Pressure Sensor Circuit High Voltage or Open
Intake air temperature pressure sensor has a signal circuit and an ECM internal ground circuit. Intake air temperature pressure
sensor is used to measure the air temperature entering the engine. ECM provides 5 V reference voltage through ECM harness
connector EO01 terminal No.9 to the intake air temperature pressure sensor harness connector EO16 terminal No.2 and an internal
low reference voltage through EO01 terminal No.19 to the intake air temperature pressure sensor EO16 terminal No.1. When the
intake air temperature pressure sensor in cold, the sensor resistance is relatively high. When the air temperature rises, the sensor
resistance decreases. When the sensor resistance is high, ECM detected intake air temperature pressure sensor signal circuit
voltage is high. With the decrease of sensor resistance, ECM detected intake air temperature pressure sensor signal circuit voltage
also decreases.
