2022年10月20日 · The Intake Air Temperature (IAT) sensor is built into the Mass Air Flow (MAF) sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature.

The P0112 code for Isuzu vehicles indicates a problem with the Intake Air Temperature (IAT) Sensor Circuit, specifically detecting low voltage. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for …

In this video we're taking a look at the intake air temperature sensor. Common trouble symptoms if this sensor fails includes improper idling and poor driving characteristics. On many late model...

Intake Air Temperature Sensor: Service and Repair. Mass Air Flow (MAF)/Intake Air Temperature (IAT) Sensor Replacement. Removal Procedure. 1. Turn off the ignition. 2. Disconnect the MAF/IAT sensor connector. 3. Loosen the MAF/IAT sensor screw (2). 4. Remove the MAF/IAT sensor (1). Installation Procedure. 1. Install the MAF/IAT sensor (1). 2.

2022年3月27日 · I’ve replaced the fuel pump, fuel filter, injector o-rings, fuel pressure regulator, and a new IAT sensor with a new pigtail because the old one was sort of cut off and mangled and also cleaned the MAP sensor.

OBDII Isuzu Code Definitions. Be sure to double check the codes. Anything P1000 to P1999 or P3000 to P3400 will be Manufacturer specific and may not match the ones listed here. Check specific manufacturer pages on the site, as some of them, we list the OBD2 codes on those pages for those specific vehicles.

The intake air temperature (IAT) sensor is fitted between the air cleaner and turbocharger. The IAT sensor is a variable resistor. The IAT se nsor measures the temperature of the air entering the engine. The engine control module (ECM) supplies 5 volts to the I AT sensor signal circuit and a ground for the IAT senso low reference circuit.
