What are the diagnostic codes for intake air temp?

Here are some of the specific symptoms you’ll see/have: Diagnostic Trouble Codes: 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.

How to test the intake air temp ( IAT )?

Testing the intake air temperature (IAT) sensor, which is located inside the mass air flow (MAF) sensor, can easily be done with a scan tool and/or a multimeter.

What does low voltage mean on intake air temp sensor?

What should intake air temp be at idle?

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. Start the engine and let it idle for about 20 minutes or until the cooling fan comes on to allow the engine to reach operating temperature.

Testing the intake air temperature (IAT) sensor, which is located inside the mass air flow (MAF) sensor, can easily be done with a scan tool and/or a multimeter.

Can a smoke machine diagnose an intake manifold leak?

A smoke machine allows you to diagnose multiple leaks in less time compared to other methods. A smoke machine can pressurize the intake manifold and put smoke or vapor into the system. If there is a leak, you will see smoke come out. Connect the smoke machine to a vacuum port like the supply line to the brake booster.
