Diagnostic Trouble Code P0113

Diagnostic trouble code P0113; This code indicates that there is a problem with the IAT sensor. The IAT sensor monitors the temperature of the air entering the engine through the air intake system and sends this information to the ECM. The ECM uses this information to determine how much fuel should be added to combustion chambers during each cycle.

P0113 is an OBD-II code that occurs when the engine control module (ECM) detects a voltage from the intake air temperature (IAT) sensor that is out of range.

The P0113 trouble code is a generic diagnostic trouble code (DTC) and can indicate many problems. The most common cause of this OBD-II code is that the vehicle’s engine control module (ECM) has detected a voltage from the intake air temperature (IAT) sensor that is out of range.

The IAT sensor measures air temperature in order to help determine how much fuel should be injected into your engine at any given moment. It does this by sending information to your ECM, which then uses that information along with other data points like throttle position and coolant temperature to determine how much fuel should be injected into your engine based on what it thinks you want as far as power output goes.

The ECM monitors this system by constantly checking for voltage readings from each individual component every few thousandths of a second; if there are any issues detected with any components, they’ll show up as one or more trouble codes in its memory logs.

The IAT sensor monitors the temperature of the air entering the engine through the air intake system.

Replacement IAT Sensor

The IAT sensor monitors the temperature of the air entering the engine through the air intake system. The IAT sensor is connected to a feed wire and ground wire; it’s powered by 5 volts of power (as opposed to 12 volts). It’s an important part of your car’s emissions control system, so make sure you have it installed properly in order to pass an emissions test.

The IAT is connected to a feed wire and ground wire. The IAT is powered by 5 volts of power.

The IAT sensor is located in the air intake system, which is in front of the engine. The IAT sensor monitors the temperature of the air entering the engine. This information is sent to your vehicle’s computer, which adjusts fuel and spark timing based on how cold or hot it thinks your engine is running.

The IAT sensor is powered by 5 volts of power from a feed wire and ground wire that connect to it at its terminals.

The IAT sensor and connector should be inspected for damage or corrosion.

Inspect the IAT sensor connector for damage or corrosion.

Also, DTC P0113 stands for “Intake Air Temperature Circuit High Input”. In this case, if the code is set again after clearing it, there could be a problem with the intake air temperature (IAT) sensor. The IAT sensor is built into the mass airflow sensor so you’ll need to replace it as an assembly. This code will not cause a serious drivability issue. Code P0113 applies to the vehicles in the chart below:

DTC P0113

P0113 is a diagnostic trouble code that indicates the intake air temperature sensor (IAT) is reporting a value that is too high. This code will not cause any serious drivability issues, but it’s important to repair it right away. The IAT system may be stuck in the open position or there could be an electrical problem with the IAT circuit.

The following vehicles use this sensor:

  • 2007-2008 Chevrolet Silverado 1500, 2007-2008 GMC Sierra 1500, 2007-2008 Cadillac Escalade ESV and EXT

What does Code P0113 Mean?

If you get a P0113 code, it means that the mass airflow sensor has detected an error in your vehicle’s engine. This is not a serious problem and will not cause any drivability issues, but it would be wise to get it checked out by a professional mechanic as soon as possible.

A common reason why this fault occurs is when there is an obstruction of some kind between the mass airflow sensor and the engine. Mechanics recommend replacing this component if it comes back after being cleared from memory because even though it won’t cause any immediate damage, over time it could lead to more serious problems with your car’s emissions system

This code is not a serious issue, and will not cause any drivability issues. This code applies to the vehicles in the chart below:

Replacing the mass airflow sensor assembly should solve this problem

If you’ve run into this code and it’s still not fixed, try replacing the mass airflow sensor assembly. To do so, you will need to replace the intake air temperature sensor harness and connector too.

Conclusion

If you have an engine that is misbehaving and you are getting P0113, it could be one of a few different problems. The first thing we recommend is to check the IAT sensor and connector for damage or corrosion. If there are any signs of damage or corrosion, then it may be time to replace these parts.
