P1223 Code Nissan:
The P1223 code in a Nissan vehicle indicates that there is a problem with the throttle position sensor 2 circuit. This means that the signal being sent from the sensor to the engine control module is too low, indicating that the throttle is not opening as it should. This can cause a variety of issues, including poor acceleration, stalling, and even engine damage if left untreated. To fix this issue, the throttle position sensor should be inspected and replaced if necessary. Additionally, the wiring and connections to the sensor should be checked for any damage or corrosion that could be causing the low signal. Once the issue is resolved, the code can be cleared from the vehicle’s computer using a diagnostic tool.
What are the Signs or Symptoms of P1223 Code in Nissan?
The P1223 code in Nissan indicates a problem with the Throttle Position Sensor (TPS) 2 circuit. This sensor is responsible for monitoring the position of the throttle valve and sending signals to the Engine Control Module (ECM) to adjust the air-fuel mixture and engine performance accordingly. When the TPS 2 circuit is not functioning properly, it can cause a range of symptoms that can affect the drivability and performance of the vehicle.
Here are some of the common signs and symptoms of the P1223 code in Nissan:
- Check Engine Light: The most obvious symptom of the P1223 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 and requires immediate attention.
- Reduced Engine Power: A faulty TPS 2 circuit can cause the engine to lose power or acceleration. This can be especially noticeable when trying to accelerate from a stop or when driving uphill.
- Stalling: In some cases, the engine may stall or shut off completely when the TPS 2 circuit is malfunctioning. This can be dangerous if it happens while driving at high speeds or in heavy traffic.
- Poor Fuel Economy: A faulty TPS 2 circuit can also cause the engine to consume more fuel than usual, leading to decreased fuel economy and higher costs at the gas pump.
- Rough Idling: The engine may also experience rough idling or hesitation when the TPS 2 circuit is not functioning properly. This can be felt as a vibration or shaking in the vehicle.
If you notice any of these symptoms in your Nissan vehicle, it is important to have it diagnosed and repaired as soon as possible. Ignoring the P1223 code can lead to further damage to the engine or emissions system, and may even result in a breakdown or accident on the road. A qualified mechanic can use diagnostic tools to identify the root cause of the problem and recommend the appropriate repairs to restore your vehicle’s performance and safety.This response was truncated by the cut-off limit (max tokens).

P1223 Code Nissan:
The P1223 code in Nissan vehicles indicates a problem with the Throttle Position Sensor (TPS) 2 circuit. The TPS is a sensor that measures the position of the throttle valve and sends this information to the Engine Control Module (ECM). The ECM uses this information to control the fuel injection and ignition timing. When the TPS 2 circuit is not functioning properly, it can cause a variety of issues with the engine’s performance.
- Failed TPS: The most common cause of the P1223 code is a failed TPS. Over time, the TPS can wear out or become damaged, causing it to send incorrect signals to the ECM. This can cause the engine to run poorly, with symptoms such as rough idle, hesitation, and poor acceleration.
- Wiring Issues: Another possible cause of the P1223 code is wiring issues in the TPS 2 circuit. If the wiring is damaged or corroded, it can cause the TPS to send incorrect signals to the ECM. This can cause the engine to run poorly, with symptoms similar to a failed TPS.
- ECM Issues: In rare cases, the P1223 code may be caused by a problem with the ECM itself. If the ECM is not receiving the correct signals from the TPS, it may not be able to control the engine’s performance properly. This can cause a variety of issues, including poor acceleration, rough idle, and hesitation.
- Throttle Body Issues: In some cases, the P1223 code may be caused by issues with the throttle body. If the throttle body is dirty or damaged, it can cause the TPS to send incorrect signals to the ECM. This can cause the engine to run poorly, with symptoms similar to a failed TPS.
- Other Issues: There are a variety of other issues that can cause the P1223 code, including vacuum leaks, fuel system issues, and ignition system issues. These issues can cause a variety of symptoms, including poor acceleration, rough idle, and hesitation.

Fixes for P1223 Code Nissan
The P1223 code in Nissan vehicles indicates a problem with the Throttle Position Sensor 2 Circuit, specifically a low input. This can cause issues with the engine’s performance and may result in reduced power or stalling. Here are some possible fixes for this code:
1. Replace the Throttle Position Sensor
The most common cause of the P1223 code is a faulty Throttle Position Sensor (TPS). If this is the case, replacing the sensor should fix the problem. The TPS is responsible for sending signals to the engine control module (ECM) about the position of the throttle, which helps the ECM determine how much fuel and air to deliver to the engine. A malfunctioning TPS can cause the ECM to receive incorrect signals, leading to poor engine performance.
2. Check the Wiring and Connections
If the TPS is not the problem, the next step is to check the wiring and connections in the circuit. A damaged or corroded wire or a loose connection can cause a low input signal to the ECM. Inspect the wiring and connections carefully and repair or replace any damaged components as needed.
3. Clean the Throttle Body
A dirty or clogged throttle body can also cause the P1223 code. Over time, dirt and debris can build up in the throttle body, restricting airflow and causing the TPS to send incorrect signals to the ECM. Cleaning the throttle body can help to restore proper airflow and improve engine performance.
4. Check the ECM
In rare cases, the problem may be with the ECM itself. If all other components have been checked and are functioning properly, it may be necessary to replace the ECM to fix the P1223 code.
In conclusion, the P1223 code in Nissan vehicles can be caused by a variety of issues, but the most common cause is a faulty Throttle Position Sensor. Replacing the sensor, checking the wiring and connections, cleaning the throttle body, and checking the ECM are all possible fixes for this code. It is important to address the issue promptly to avoid further damage to the engine and ensure proper performance.
