Error Code P0113: Intake Air Temperature Circuit High Input

Error code P0113 indicates that the computer has received a high voltage signal from the intake air temperature sensor. This code will occur when the powertrain control module (PCM) receives a voltage of 5 volts or more from the IAT. This indicates a problem between the IAT and the PCM.

Definition

The vehicle’s PCM, or computer, sends a consistent reference voltage of about 5 volts to the IAT. Because it is a thermistor, the IAT resists that charge based on its temperature and the resulting voltage is returned to the PCM. The PCM uses this information to adjust such things as the air/fuel mixture and EGR valve.

If the IAT sends a voltage to the PCM that is in excess of 5 volts, the PCM returns the P0113 code. This error code is specific to voltage and will not be set if the IAT is simply returning unusual readings.

Common Symptoms

  • Check Engine Light Appears
  • Air/Fuel Mixture is Too Lean or Too Rich
  • Idles Poorly When Cold
  • Faulty EGR Valve Operation
  • Poor Fuel Economy
  • Increased Emissions

Possible Causes

  • The IAT is corroded or defective
  • Backfiring has occurred in the intake manifold
  • The tip of the sensor has been contaminated by oil
  • A wiring connector has corroded or detached
  • The IAT circuit has been shorted
  • The PCM has failed

What to Check

If the check engine light appears, use an OBD-II scanner to assess the error code. If it returns a P0113 error, there are a few things to examine.

Check the Air Temperature Reading

Allow the engine to run until it is warm. Use a scan gauge to compare the air temperature reading to the coolant temperature. Typically, a functional IAT sensor will report a slightly lower temperature than the coolant temperature sensor.

Examine Wiring Between the PCM and IAT

This error can be caused by wiring that has come loose or corroded, so examine the physical circuit between the IAT and the vehicle’s computer.

Test the Resistance

First, remove the IAT from the vehicle. Using an ohmmeter, measure the resistance of the IAT at room temperature. Then apply heat to the IAT sensor tip with a hair dryer and check to see if the resistance has decreased. No change in resistance or an infinite resistance reading indicate that the IAT sensor is faulty.

How to Fix It

Because a P0113 code is most frequently caused by either a dysfunctional circuit or a failed IAT sensor, the most common repair is simply replacing the faulty component. You can also try cleaning the IAT sensor tip and replacing the grounds.

Replacement IAT sensors are not usually very expensive, so replacing one is not a costly repair. Furthermore, a P0113 error may very rarely indicate a problem with the PCM. After you’ve fixed the IAT, clear the error codes and run the vehicle. If the P0113 code reappears, that could indicate a faulty PCM.

P0113 Intake Air Temperature Circuit High Input on 2000 Hyundai Elantra

When you turn the key to start the engine, the engine control module (ECM) looks at data from the engine coolant temperature sensor (ECT), the intake air temperature sensor (IAT), throttle position sensor (TPS), and the mass airflow sensor (MAF). Based on the readings from all those sensors, the ECM determines the proper air/fuel mixture to start and run the engine. However, if the data from one of those sensors is bad, the air/fuel mixture will be too rich or too lean. Either of those conditions can cause a hard start and poor idling.
In this case, the P0113 trouble code is indicating that the IAT sensor is sending a high voltage signal to the ECM, making it think the incoming air is really cold when it’s not. You can test the IAT with a digital volt ohmmeter (DVOM). Set it to the volts scale and connect one lead to a good ground. Back-probe the green/black wire at the IAT with the key in the RUN position. Voltage should read approximately 2.4-2.8-volts when outside air temperature is 68°F (1.6-2.0-volts at 104°F). If the reading is higher than the corresponding outside temperature dictates, the IAT may be malfunctioning. However, there’s also a possibility that the 5-volts provided to the IAT by the ECM is shorting to the green/black wire in the wiring harness. You can replace the IAT (the most likely suspect) for about $10, or you can check for a short in the wiring harness. To check the harness, unplug the connector from the IAT and check the voltage at the green/black wire at the ECM. It should be 0-volts.

2011 Hyundai Santa Fe Fwd OBD2 Code P0113 Intake Air Temperature Sensor 1 Circuit High

What Does P0113 Code Mean?

OBD-II Code P0113 is defined as a Intake Air Temperature Circuit High Input

The Intake Air Temperature Sensor measures the rise and fall of the air temperature inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing and many components of the Emission Control Systems.

Code P0113 sets when the voltage signal to the PCM from the Intake Air Temperature Sensor Circuit stays above 4.5 volts while the Coolant Temperature Voltage readings are rising and falling within an appropriate range.

P0113 Symptoms

  • Check Engine Light will illuminate
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • Poor engine performance/hesitation on acceleration

Common Problems That Trigger the P0113 Code

  • Defective Intake Air Temperature Sensor
  • Dirty air filter
  • Defective Mass Air Flow Sensor
  • Faulty or corroded Intake Air Temperature Sensor wiring or connections

Common Misdiagnoses

  • Intake Air Temperature Sensor is replaced when the real cause is a dirty air filter
  • Intake Air Temperature Sensor is replaced when the real cause is a poor connection or chafed wiring
  • Intake Air Temperature Sensor is replaced when the real problem is in the Mass Air Flow Sensor

Polluting Gases Expelled

  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog
  • CO (Carbon Monoxide): Partially burned fuel that is an odorless and deadly poisonous gas
  • NOX (Oxides of Nitrogen): One of the two ingredients that, when exposed to sunlight, cause smog

P0113 Diagnostic Theory for Shops and Technicians

When diagnosing a P0113 code, it is important to record the freeze frame information and then to duplicate the code setting conditions with a test drive while paying close attention to engine load, throttle position, RPM, and road speed on a data streaming scan tool. As you drive the vehicle, compare these values to the Intake Air Temperature Sensor PID or parameter ID. The Intake Air Temperature Sensor voltage values should rise and fall with changes in engine temperature. Compare the Intake Air Temperature or IAT readings to the Coolant Temperature Sensor readings, as they should move in tandem with each other. However, the Engine Coolant Temperature sensor will have a much higher temperature range.

Check the IAT sensor connector with the key on and the engine off. There needs to be a steady 5 volt reference voltage and a very good ground. Find and use the proper engine performance wiring diagram to discern the proper color and position of these wires in the connector.

It never hurts to do a key on-engine off voltage output test of the IAT sensor. Typically, I CAREFULLY use a heat gun to raise the temperature of the area around the sensor and study the change in values of the Intake Air Temperature. It's important to use the scan tool data stream as this will verify the IAT harness and connections.

P0113 hyundai

P0113 is an OBDII trouble code that occurs when the Hyundai Elantra’s engine management computer detects that there is an issue with the Intake Air Temperature (IAT) Sensor, specifically that there is a High Input Problem with it.

P0113: IAT Sensor – High Input Problem

The IAT sensor is responsible for measuring the air temperature and density to achieve the optimal air/fuel mixture for any condition.

P0113 is specifically thrown when the Elantra’s computer sees a voltage signal of 4.91 volts for over half a second at the Intake Air Temp Sensor. If there are irregularities in the voltage, it will not throw P0113, it’s only for excess voltage.

 

Hyundai Elantra P0113 Symptoms

There can be symptoms associated with P0113. Depending on the time of year, IAT sensor issues can be a real problem. When it is cold outside, it may be more difficult for your Elantra’s engine to start. This is due to a lean condition that’s more noticeable when the air temperature is lower.

Here are the most common symptoms of P0113/IAT issues:

  • Service Engine Soon– Often, the only noticeable symptom of P0113 is going to be the service engine soon light.
  • Hard Starts– the engine may have difficulty starting due to the IAT issue creating a leaner air fuel mixture. As stated above, this problem will only be magnified when it is cold outside in the engine needs more of a choke to start.
  • Lean Condition– As stated above, the engine will run lean with P0113. It is not a good idea to drive around for a long time with an engine is running lean. We recommend getting it in to be repaired as soon as possible. Once the engine is warmed up though, it should not leave you stranded.
  • Decreased Fuel Economy– With the engine running lean, it’s not going to produce the optimal power for good fuel economy.

P0113 Diagnosis: Hyundai Elantra

Here’s a really helpful YouTube video that has a lot of good information to help diagnose P0113.

When most folks see this trouble code, they will replace the IAT sensor right away. It is often a mistake to replace the sensor immediately, often it will be a wiring issue.

It’s a good idea to inspect the wiring around the sensor, and make sure that there are no obvious signs of damage, or that it is even plugged in. After that, use a multimeter to make sure that it is getting the proper voltage. A good scan tool can tell you a lot about what exactly is going on with your engine and causing the P0113.

If you have looked around the harness and there does not seem to be any discernible problem, it will most likely be the IAT sensor that needs replaced.

Here are some of the most common causes of P0113, presented (somewhat) in order from most likely to least likely:

  • IAT is bad, and needs replaced.
  • IAT is good, but oil has contaminated it (on the tip).
  • Wiring harness has been damaged/shorted: How to Diagnose a Short in a Car (youtube) Find a short in a car (article).
  • Backfiring has occurred in the intake manifold. This can fry/contaminate the sensor.
  • PCM failure.

 

Conclusion

While P0113 is not going to leave you stranded on the side of the road, it is important to not ignore it. If you allow your Hyundai Elantra to run lean for too long of a period of time, it’ll develop other problems with the engine. Good luck fixing your vehicle.

P0113 OBD-II Trouble Code: IAT Sensor Circuit High Input Problem

P0113 code definition

Intake Air Temperature (IAT) sensor circuit high input problem

What the P0113 code means

P0113 is the OBD-II generic code that the engine control module (ECM) has recorded the IAT sensor output above expected sensor range.

What causes the P0113 code?

If the sensor output voltage is more than 4.91 V for 0.5 seconds or more, the ECM determines that there is an open circuit in the IAT sensor circuit, and sets trouble code P0113.

What are the symptoms of the P0113 code?

  • The ECM will turn on the Check Engine Light and go into a failsafe mode.
  • Engine may not start as usual
  • Engine may run extra lean
  • Engine may have pre-ignition problems from lean burn conditions

Note: The symptoms are determined by the manufacturer failsafe ECM strategy for the vehicle during a failure and may vary between manufacturers and vehicles.

How does a mechanic diagnose the P0113 code?

  • Scans the ECM, documents the codes received, and views the freeze frame data to see the conditions present when the code was set

  • Clears the vehicle of fault codes and the retests the vehicle to see if the code comes back

  • Performs a visual inspection to check for shorting harness or connector to sensor

  • Observes the sensor’s live data on the scanner while disconnecting the IAT sensor connector to see if the sensor reading goes to -40°F indicating the sensor is shorted

If the sensor is disconnected and input is still 240°F then the short is in the connector or harness.

If no problems are noted, the mechanic performs the manufacturer's specific pinpoint tests for the code and repair as needed.

Common mistakes when diagnosing the P0113 code

  • Not performing a visual inspection of connections and wiring

  • Not following the manufacturer pinpoint test procedure step-by-step and skipping steps

  • Not replacing an IAT sensor only when tests indicate a problem

  • Not connecting a new or known good sensor to the harness and viewing the ECM data to see if the temperature output from the sensor is as expected

How serious is the P0113 code?

  • The P0113 code will cause the engine ECM to go into a failsafe mode.

  • The failsafe mode, depending on the manufacturer failsafe mode strategy, may cause lean condition drivability symptoms.

  • Driving the vehicle for an extended time running too lean can cause internal engine problems with rings and valves.

What repairs can fix the P0113 code?

  • Repairing or replacing the IAT connector short
  • Repairing or replacing the wiring short as necessary
  • Replacing the IAT with a new sensor

Additional comments for consideration regarding the P0113 code

  • The P0113 code is often associated with P0111, P0112, and P0114 codes.

  • Most intake air temperature sensor problems for code P0113 are failures from damaged shorted harnesses or from sensors shorted internally to power.
