P0113 Nissan Code - Intake Air Temperature Sensor Circuit High

Quick Answer

The Intake Air Temperature (IAT) sensor is built into the Mass Air Flow (MAF) sensor or in some vehicles mounted to the air filter duct housing. Common causes include Faulty Intake Air Temperature (IAT) Sensor (for most vehicles built into Mass Air Flow [MAF] Sensor), Dirty air filter, Intake Air Temperature sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0113 Nissan Description

The Intake Air Temperature (IAT) sensor is built into the Mass Air Flow (MAF) sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle. The Diagnostic Trouble Code (DTC) will be set when an excessively high voltage from the sensor is sent to ECM.

- Common symptoms include poor engine performance, rough idling, decreased fuel efficiency, and illuminated Check Engine Light.

2. What does the OBDII code P0113 in a Nissan indicate?

- The code P0113 indicates a problem with the Intake Air Temperature (IAT) sensor circuit registering a high voltage.

3. What are the possible causes of OBDII code P0113 in a Nissan?

- Possible causes include a faulty IAT sensor, damaged wiring or connectors in the sensor circuit, or issues with the Engine Control Module (ECM).

4. How can I diagnose the cause of OBDII code P0113 in my Nissan?

- You can diagnose the code by visually inspecting the sensor and its wiring, checking for any signs of damage or corrosion. Using a multimeter to test the sensor's resistance can also help pinpoint the issue.

5. What is the function of the Intake Air Temperature (IAT) sensor in a Nissan?

- The IAT sensor measures the temperature of the air entering the engine, helping the ECM adjust the air-fuel mixture for optimal engine performance.

6. Can I drive my Nissan with OBDII code P0113 present?

- It is generally not recommended to drive with this code present, as it can lead to decreased engine performance and potential damage if left unresolved.

7. How can I repair OBDII code P0113 in my Nissan?

- Repairing the code typically involves replacing the faulty IAT sensor, repairing damaged wiring or connectors, or addressing any ECM issues as needed.

8. Are there any DIY tips for resolving OBDII code P0113 in a Nissan?

- DIY tips include checking for loose or damaged wiring, ensuring the sensor is clean and properly connected, and clearing the code to see if it reoccurs after repairs.

9. How much does it cost to fix OBDII code P0113 in a Nissan?

- The cost of fixing this code can vary depending on the specific issue, but it may range from $50 to $200 for parts and labor.

10. Can a faulty IAT sensor cause other problems in a Nissan besides triggering OBDII code P0113?

- Yes, a faulty IAT sensor can also lead to issues such as poor engine performance, rough idling, and incorrect air-fuel mixture, affecting overall vehicle drivability.

  • Another possible cause is PCM failed. This is shown on other reliable sites as well.

  • I have a 2008 Nissan Altima 2.5s. Ive replaced the engine and months later had to replace the transmission. Ive recently gotten the car out the shop and it was running fine . Days later, I decided to drive it and once I put the car in reverse, it would not accelerate. Once on the road, the car was not opening up how it should. I thought it was the fuel pump/filter. So I had that replaced as well. I had the car read, two code appeared: P0845 and P0113. What steps should I take? I am almost at a point where I am ready to wash my hands with this "project"

  • The P0113 is for the Intake Air Temperature (IAT) sensor which is part of the Mass Air Flow (MAF) sensor, you should start by inspecting the sensor, make sure there is nothing blocking the air flow, if possible change the air filter.

    The P0845 is a transmission code. There is a factory service bulletin for that code. The bulletin recommend replacing the Valve Body to fix the problem, but you already replace the transmission, did you use a new (rebuilt from factory) or used transmission? How is the transmission fluid level and condition?

  • I Put a brand new set of coil packs and spark plugs also l put a new crank shaft position sensor and also a set of valve cover gasket's. Now it came up with a po113 code I read the code on my code reader and it said MAF it's in the same area as the mad. So what should I do next?

  • What model and year is your Nissan? The P0113 code is for the Intake Air Temperature (IAT) sensor. On most new vehicles, the IAT sensor is part of the Mass Air Flow (MAF) sensor. The IAT and MAF are together. You need to clean or replace the MAF to fix the problem.

  • My 2003 Altima is presenting this code, but, what is the measure for that resistor?

    I checked the voltage one of the wires and the ECM is receiving 2.7 VDC more or less....

    The symptom that is presenting is accelerate - decelerate alone, 1500PRM to 2000RPM

    Any recommendations I will appreciate...

  • Start by replacing the air filter and cleaning the Mass Air Flow (MAF) sensor. If the problem persist, you may have to replace the MAF. The Intake Air Temperature (IAT) sensor is part of the MAF.

  • im having this code but no cel the armada die coming down from higher rpms

  • You could start by replacing the air filter and cleaning the Mass Air Flow (MAF) sensor, but if the problem persist, then you may have to replace the MAF.

  • Hello,

    2013 Nissan Pathfinder
    P0113 Intake Air temp Sensor 1 Circuit High
    P0102 Mass or Volume air flow circuit low

    I have replaced air filter and MAF and battery…
    Vehicle stalls after being ran for awhile. It will start right back up after a few tries or if it sits for a few minutes it starts. I have noticed loss in accelerating and power a few times while pushing on the pedal.

    Suggestions on next trouble shooting step….

  • Othe than the MAF I have not seen anything else setting the P0113 and P0102 codes. Did you had the same symptoms before replacing the MAF? did you use a new factory OEM MAF?

  • my vehicle Nissan Sunny detects P0113 AND P0110, but when i am driving it is just stoping itself and when i put a reverse it stops again. what should i do in order to take car of my car

  • Start by checking the air filter and air filter box, if possible, change the air filter. If the problem persists you may have to replace the Mass Air Flow (MAF) sensor.
