Key Takeaways: P0112 Code Nissan
Meaning: The P0112 code in Nissan indicates that the intake air temperature circuit is reading a low input signal.
Causes: The code can be caused by a faulty intake air temperature sensor, damaged wiring or connectors, or a malfunctioning engine control module (ECM).
Symptoms: Symptoms of the P0112 code may include poor engine performance, decreased fuel efficiency, and the illumination of the check engine light.
Fixes: To fix the P0112 code, you may need to replace the intake air temperature sensor, repair damaged wiring or connectors, or replace the ECM if it is malfunctioning.
P0112 Code Nissan:
The P0112 code in a Nissan vehicle indicates that there is a problem with the Intake Air Temperature (IAT) sensor circuit. This sensor is responsible for measuring the temperature of the air entering the engine and sending that information to the engine control module (ECM). When the ECM receives a signal that the IAT circuit is reading too low, it will trigger the P0112 code and turn on the check engine light.
There are several potential causes for this code, including a faulty IAT sensor, a damaged or corroded wiring harness, or a problem with the ECM itself. To diagnose the issue, a mechanic will typically use a scan tool to read the code and then perform a series of tests to determine the root cause. Once the problem has been identified, the mechanic can then make the necessary repairs to fix the issue and clear the code from the ECM’s memory.

What are the Signs or Symptoms of P0112 Code in Nissan?
The P0112 code in Nissan indicates a problem with the Intake Air Temperature (IAT) sensor circuit. This sensor is responsible for measuring the temperature of the air entering the engine and sending this information to the Engine Control Module (ECM). When the ECM detects a low input signal from the IAT sensor, it triggers the P0112 code. Here are some of the signs and symptoms that you may experience if your Nissan has this code:
- Check Engine Light: The most common symptom of the P0112 code is the illumination of the check engine light on the dashboard. This light may appear as a steady light or a flashing light, depending on the severity of the problem.
- Poor Engine Performance: Another symptom of the P0112 code is poor engine performance. You may notice that your Nissan is running rough, stalling, or hesitating when you accelerate. This is because the ECM is not receiving accurate information from the IAT sensor, which can cause the engine to run too rich or too lean.
- Reduced Fuel Efficiency: If your Nissan has the P0112 code, you may also notice a decrease in fuel efficiency. This is because the ECM is not able to adjust the fuel mixture properly based on the temperature of the air entering the engine.
- Difficulty Starting: In some cases, the P0112 code can cause difficulty starting your Nissan. This is because the ECM is not receiving accurate information from the IAT sensor, which can affect the amount of fuel that is delivered to the engine during startup.
- Other Codes: In some cases, the P0112 code may be accompanied by other codes related to the IAT sensor or the engine’s air intake system. These codes may include P0113, P0114, P0101, or P0102.
If you are experiencing any of these symptoms in your Nissan, it is important to have the problem diagnosed and repaired as soon as possible. Ignoring the P0112 code can lead to further damage to your engine and decreased performance and fuel efficiency. A qualified mechanic can use diagnostic tools to determine the exact cause of the problem and recommend theThis response was truncated by the cut-off limit (max tokens).

P0112 Code Nissan:
The P0112 code in Nissan vehicles indicates a problem with the Intake Air Temperature (IAT) sensor circuit. This sensor is responsible for measuring the temperature of the air entering the engine and sending this information to the Engine Control Module (ECM). The ECM uses this data to adjust the air/fuel mixture and ignition timing for optimal performance and fuel efficiency. When the IAT circuit is not functioning properly, it can cause a variety of issues with the engine’s performance and emissions.
Here are some of the possible causes of the P0112 code in Nissan vehicles:
- Faulty IAT sensor: The most common cause of the P0112 code is a faulty IAT sensor. Over time, the sensor can become contaminated with dirt and debris, or it may simply wear out and fail. When this happens, the ECM may receive incorrect temperature readings, which can cause the engine to run poorly or not start at all.
- Wiring issues: Another possible cause of the P0112 code is a problem with the wiring or connectors in the IAT circuit. If the wiring is damaged or corroded, it can cause a poor connection or a short circuit, which can prevent the sensor from sending accurate data to the ECM.
- Failed ECM: In rare cases, the P0112 code may be caused by a failed ECM. If the ECM is not receiving the correct signals from the IAT sensor, it may not be able to adjust the air/fuel mixture and ignition timing properly, which can cause a variety of engine performance issues.
- Other issues: There are a few other issues that can cause the P0112 code, such as a vacuum leak, a clogged air filter, or a malfunctioning Mass Air Flow (MAF) sensor. These issues can affect the air/fuel mixture and cause the engine to run poorly, which can trigger the P0112 code.
If you are experiencing the P0112 code in your Nissan vehicle, it is important to have it diagnosed and repaired as soon as possible. Ignoring this issue can lead to further damage to your engine and decreased fuel efficiency.

Fixes for P0112 Code Nissan
The P0112 code in Nissan vehicles indicates a low input in the intake air temperature circuit. This can cause various issues in the engine’s performance, such as reduced fuel efficiency, rough idling, and even stalling. Here are some fixes for the P0112 code:
- Check the Intake Air Temperature Sensor (IAT): The IAT sensor is responsible for measuring the temperature of the air entering the engine. A faulty sensor can cause the P0112 code. Check the sensor’s wiring and connections for any damage or corrosion. If everything looks fine, test the sensor’s resistance using a multimeter. If the resistance is out of range, replace the sensor.
- Inspect the Air Intake System: A clogged air filter or a blocked air intake can cause the engine to receive less air than it needs, leading to a low IAT reading. Check the air filter and the air intake ducts for any obstructions or damage. Clean or replace the air filter if necessary.
- Check the Engine Coolant Temperature (ECT) Sensor: The ECT sensor measures the temperature of the engine coolant. A faulty ECT sensor can cause the engine to run rich, which can affect the IAT reading. Test the ECT sensor’s resistance using a multimeter and replace it if necessary.
- Inspect the Wiring and Connectors: A damaged or corroded wiring or connector in the IAT circuit can cause the P0112 code. Inspect the wiring and connectors for any signs of damage or corrosion. Repair or replace any damaged components.
- Check the Engine Control Module (ECM): If all the above fixes fail to resolve the P0112 code, the issue may lie with the ECM. The ECM controls the IAT sensor’s operation and can cause the code if it malfunctions. Have a professional mechanic diagnose and repair the ECM if necessary.
In conclusion, the P0112 code in Nissan vehicles can cause various engine performance issues. However, with proper diagnosis and repair, the issue can be resolved. Check the IAT sensor, air intake system, ECT sensor, wiring and connectors, and ECM to fix the P
