P0113 Nissan Code - Intake Air Temperature Sensor Circuit High

Quick Answer

The P0113 diagnostic trouble code (DTC) for Nissan vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high voltage. Common causes include Faulty IAT Sensor: The most common cause of the P0113 code is a malfunctioning IAT sensor that is sending incorrect voltage signals to the ECM, Wiring Issues: Damaged or corroded wiring connections to the IAT sensor can result in high voltage readings, Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can cause the circuit to register a high voltage. 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 P0113 diagnostic trouble code (DTC) for Nissan vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high voltage. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency. A high voltage reading from the IAT sensor can disrupt the engine's air-fuel mixture, leading to poor performance, decreased fuel economy, and potential engine misfires.

Common Causes of P0113 Nissan

  1. Faulty IAT Sensor: The most common cause of the P0113 code is a malfunctioning IAT sensor that is sending incorrect voltage signals to the ECM.
  2. Wiring Issues: Damaged or corroded wiring connections to the IAT sensor can result in high voltage readings.
  3. Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can cause the circuit to register a high voltage.
  4. Intake Air Leak: An intake air leak near the IAT sensor can lead to false high voltage readings.
  5. ECM Malfunction: In rare cases, a malfunctioning ECM may be the underlying cause of the P0113 code.

Symptoms of P0113 Nissan

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
  2. Engine Running Rough: A high voltage reading from the IAT sensor can cause the engine to run rough or experience hesitation during acceleration.
  3. Decreased Fuel Efficiency: The incorrect air-fuel ratio resulting from the faulty IAT sensor can lead to decreased fuel efficiency.
  4. Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to the incorrect sensor readings.
  5. Poor Performance: Overall, the vehicle may exhibit poor performance, lack of power, and rough idling as a result of the P0113 code.

How to Fix P0113 Nissan

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform a visual inspection of the IAT sensor and related wiring.
  2. Test the IAT Sensor: Use a multimeter to test the IAT sensor for correct voltage readings and resistance values.
  3. Check Wiring Connections: Inspect the wiring connections for any damage, corrosion, or loose connections and repair as necessary.
  4. Replace IAT Sensor: If the sensor is faulty, replace it with a new one and ensure proper installation.
  5. Clear Error Codes: Clear the error codes from the ECM using a diagnostic scanner and test drive the vehicle to confirm the issue has been resolved.

Cost to Fix P0113 Nissan

The typical repair costs for addressing a P0113 code can range from $100 to $300, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate.

  • 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.

  • 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?

  • 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.
