What does the IAT sensor on a Jetta mean?

This means that the IAT sensor is reporting a temperature of 300 °F (149 °C). – P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage. This means that the IAT sensor is reporting a temperature of -38 °F (-39 °C). 2. BAD gas mileage. 3. Black smoke coming out of the tailpipe. 4. Won’t pass the emissions test.

What does the intake air temperature sensor say?

– P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage. This means that the IAT sensor is reporting a temperature of 300 °F (149 °C). – P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage.

What does DTC stand for on IAT sensor?

The most obvious symptom will be the check engine light (CEL) lit nice and bright on your instrument cluster. The second will be an IAT sensor malfunction diagnostic trouble code (DTC) stored in the PCM memory. 1. Diagnostic Trouble Codes:

What does a high voltage IAT sensor mean?

Where is the IAT sensor on a Ford Explorer?

An IAT sensor located on the air duct of a Ford Explorer. Author’s own photo. A bad intake air temperature (IAT) sensor may cause one or more of the following symptoms: lean misfire, usually in a cold engine Faulty EGR system (in some applications)

How to test the intake air temperature sensor?

P0113: Intake air temperature sensor circuit high (voltage) input Basically, your IAT sensor may fail in one or more of these ways: Whether you find a sensor-related DTC or not, if you suspect a problem with the IAT sensor, you should: Check the sensor itself. if necessary, inspect the wiring and connectors in the sensor’s circuit.

What to do if you find a problem with your IAT sensor?

Whether you find a sensor-related DTC or not, if you suspect a problem with the IAT sensor, you should: Check the sensor itself. if necessary, inspect the wiring and connectors in the sensor’s circuit. Check for a dirty or clogged air filter.

Where is the air temperature sensor on a Ford Explorer?

Dan Ferrell writes about do-it-yourself car maintenance and repair. He has certifications in automation and control technology. An IAT sensor located on the air duct of a Ford Explorer. Author’s own photo. A bad intake air temperature (IAT) sensor may cause one or more of the following symptoms:

What should intake air temp be with engine off?

With the engine off, measure the sensor resistance across its terminals. At about 68 F (20 C), you should get around 37K ohms At about 86 F (30 C), you should get around 24K ohms Plug in the sensor electrical connector.

What is the code for the air temperature sensor?

· If the temperature reading displays -30 to -40°F, the dashboard light should show the code P0113, and if the reading displays 300°F, the dashboard should show the code P0112. · If the reading shows a temperature of 300°F, you need to check if the MAF sensor wires are shorted because of the internal copper getting exposed to each other.
