What does high voltage on IAT sensor 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). Bad gas mileage. Black smoke coming out of the tailpipe.
Is the IAT built into the MAF sensor?
On some module with a mass air flow (MAF) sensor, the IAT is incorporated into the same housing On some models with a manifold absolute pressure (MAP) sensor, the IAT is built into the sensor as well. If necessary, consult your vehicle repair manual to locate the sensor. III. Different Names for the IAT Sensor
How to test the intake air temperature ( IAT ) sensor?
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. In this article, I’ll show you how to test IAT sensor in a step-by-step way that will help you say that, ‘Yes, it’s BAD’ or ‘No, it’s not BAD’.
What are the symptoms of an IAT sensor malfunction?
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. Here are some of the specific symptoms you’ll see/have: P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage.
What is the diagnostic code for an IAT sensor?
The fault may lie in other parts of the IAT circuit, such as the connection. If the sensor is faulty, a replacement part can cost anywhere between $1.94 to $110.93 on CarParts.com. There are other diagnostic trouble codes that cover the IAT sensors and their attendant circuitry. For example, an intermittent IAT sensor signal falls under P0114.
What is the trouble code for the MAF sensor?
The troublecode P0100 is set when the MAF sensor circuit is malfunctioning. This code is similar to P0104 – MAF sensor circuit intermittent. The difference between the two codes is the consistency of the malfunction in the MAF sensor circuit. Troubleshooting will be the same for both codes.
How much does it cost to replace an IAT sensor?
It’s also worth noting that not every instance of a P0113 trouble code requires replacement of the IAT sensor. The fault may lie in other parts of the IAT circuit, such as the connection. If the sensor is faulty, a replacement part can cost anywhere between $1.94 to $110.93 on CarParts.com.
Where is the IAT sensor in the intake manifold?
It can be located on the air cleaner, in the air inlet tube, or in the intake manifold. The IAT sensor is a two-wire sensor with a negative temperature coefficient resistor positioned so that it reads the air entering the engine.
