P1126 Code Nissan:
The P1126 code in a Nissan vehicle indicates that there is an issue with the throttle control motor relay circuit. This means that the engine control module (ECM) is not receiving the proper signal from the throttle control motor relay, which can cause a variety of problems with the vehicle’s performance.
Some common symptoms of a P1126 code include a lack of power or acceleration, rough idling, and stalling. In some cases, the vehicle may also experience a decrease in fuel efficiency or difficulty starting.
To fix a P1126 code, the first step is to diagnose the underlying issue. This may involve checking the wiring and connections in the throttle control motor relay circuit, as well as testing the relay itself. In some cases, the issue may be with the ECM or another component of the vehicle’s electrical system.
Once the issue has been identified, the appropriate repairs can be made. This may involve replacing damaged wiring or components, or reprogramming the ECM to correct any software issues. In some cases, it may be necessary to replace the entire throttle control motor relay circuit.
What are the Signs or Symptoms of the P1126 Code in Nissan?
The P1126 code in Nissan indicates a problem with the throttle control motor relay circuit. This code is usually triggered when the Engine Control Module (ECM) detects an open circuit in the throttle control motor relay circuit. Here are some of the signs and symptoms that you may experience if your Nissan has a P1126 code:
- Check Engine Light: The most common symptom of the P1126 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine or emissions system.
- Reduced Engine Power: Another symptom of the P1126 code is reduced engine power. You may notice that your Nissan is not accelerating as quickly as it used to or that it is struggling to maintain speed.
- Stalling: In some cases, the P1126 code can cause your Nissan to stall or shut off completely. This can be dangerous if it happens while you are driving.
- Difficulty Starting: If the P1126 code is causing problems with the throttle control motor relay circuit, you may have difficulty starting your Nissan. This is because the engine may not be getting the proper amount of fuel or air.
- Poor Fuel Economy: If your Nissan is experiencing reduced engine power or stalling, it may also be getting poor fuel economy. This means that you will have to fill up your gas tank more frequently than usual.
If you are experiencing any of these symptoms, it is important to have your Nissan diagnosed by a qualified mechanic as soon as possible. Ignoring the P1126 code can lead to further damage to your engine or emissions system, which can be expensive to repair.
P1126 Code Nissan:
The P1126 code in Nissan vehicles indicates a problem with the throttle control motor relay circuit. This code is usually triggered when the Engine Control Module (ECM) detects an open circuit in the relay that controls the throttle motor. Here are some of the possible causes of the P1126 code:
- Failed Throttle Control Motor Relay: The most common cause of the P1126 code is a failed throttle control motor relay. This relay is responsible for controlling the throttle motor, which regulates the airflow into the engine. If the relay fails, the ECM will not be able to control the throttle motor, resulting in the P1126 code.
- Wiring Issues: Another possible cause of the P1126 code is wiring issues in the throttle control motor relay circuit. If there is a break or short in the wiring, the ECM will not be able to communicate with the throttle motor relay, resulting in the P1126 code.
- Failed Throttle Motor: In some cases, a failed throttle motor can also trigger the P1126 code. If the throttle motor fails, the ECM will not be able to regulate the airflow into the engine, resulting in the P1126 code.
- Failed ECM: Although rare, a failed ECM can also trigger the P1126 code. If the ECM is not able to communicate with the throttle control motor relay, it may trigger the P1126 code.
- Other Issues: Other issues such as a faulty accelerator pedal position sensor, throttle position sensor, or mass airflow sensor can also trigger the P1126 code. However, these issues are less common than the ones mentioned above.
If you are experiencing the P1126 code in your Nissan vehicle, it is important to have it diagnosed and repaired as soon as possible. Ignoring this code can lead to further damage to your vehicle and can even result in a dangerous situation while driving. A certified mechanic can diagnose the issue and recommend the necessary repairs to fix the problem.This response was truncated by the cut-off limit (max tokens).

Fixes for P1126 Code Nissan
The P1126 code in Nissan vehicles indicates a problem with the throttle control motor relay circuit. This can cause issues with the engine’s performance and may even result in the vehicle stalling. Fortunately, there are several fixes for this code that can help get your Nissan back on the road.
- Check the Throttle Control Motor Relay: The first step in fixing the P1126 code is to check the throttle control motor relay. This component is responsible for controlling the throttle motor and ensuring that it operates correctly. If the relay is faulty, it can cause the circuit to open and trigger the P1126 code. If the relay is faulty, it will need to be replaced.
- Inspect the Wiring and Connections: Another common cause of the P1126 code is damaged or corroded wiring and connections. Over time, the wiring and connections can become damaged due to exposure to heat, moisture, and other elements. Inspecting the wiring and connections and repairing any damage can help resolve the issue.
- Replace the Throttle Control Motor: If the throttle control motor is faulty, it can cause the circuit to open and trigger the P1126 code. In this case, the throttle control motor will need to be replaced. It’s important to ensure that the replacement motor is compatible with your Nissan model.
- Reset the Engine Control Module (ECM): In some cases, the P1126 code may be triggered due to a temporary glitch in the ECM. Resetting the ECM can help clear the code and resolve the issue. To reset the ECM, disconnect the battery for a few minutes and then reconnect it.
- Replace the Engine Control Module (ECM): If none of the above fixes work, it may be necessary to replace the ECM. This is a more expensive fix, but it may be necessary if the ECM is damaged or faulty.
