P0112 is the OBD-II generic code that the engine control module (ECM) has recorded the IAT sensor input below the expected sensor range.
Where is the intake air temperature sensor located?
Zitat von Youtube: The intake air temperature sensor that's located right here on the inlet to the air filter housing very simple straightforward to get it.
What is code P0112 mean?
Intake Air Temperature Circuit Low Input
OBD-II Code P0112 is defined as a Intake Air Temperature Circuit Low Input. The Intake Air Temperature Sensor measures the rise and fall of the air temperature inside the Intake Manifold.
What causes intake air temperature sensor fault codes?
This sensor, in turn, uses a thermistor to measure the intake air temperature. If the temperature remains normal, the thermistor will have some resistance meaning the output voltage to the PCM will be below 5 volts. A P0113 OBD-II trouble code is triggered when the voltage signal to the PCM is higher.
How do you fix an IAT sensor?
Zitat von Youtube: Sensor. First carefully remove the iat sensor from the vehicle visually inspect the sensor to make sure it hasn't been contaminated by a leak from another engine component.
How is P0128 diagnosed?
The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.
What is intake temperature sensor?
The Intake Air Temperature (IAT) Sensor is used by the engine’s Power Control Module (PCM) to decide at which rate the engine should spark and inject fuel to obtain optimal performance.
How do you test an intake air temperature sensor?
Zitat von Youtube: The hotter the air the lower the output voltage. To test connect the multimeter. Read lead to battery positive and the black lead to the sensor ground wire.
Can you clean intake temperature sensor?
To clean the intake air temp sensor: remove the duct from the throttle body and spray the sensor. Two or three shots will remove almost any oil-based contamination from it. The stuff dries fast, almost instantly.
