Signs and Symptoms of P0204 Code in Nissan
The P0204 code in Nissan indicates a problem with the number 4 fuel injector circuit. This code is usually triggered when the Engine Control Module (ECM) detects an open circuit in the fuel injector circuit. Here are some of the signs and symptoms that you may experience if your Nissan has a P0204 code:
- Check Engine Light: The most common symptom of the P0204 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine that needs to be addressed.
- Engine Misfire: Another common symptom of the P0204 code is an engine misfire. This occurs when the fuel injector is not delivering the proper amount of fuel to the engine, causing it to run rough or stall.
- Poor Fuel Economy: If the fuel injector is not working properly, it can cause the engine to use more fuel than necessary, resulting in poor fuel economy.
- Difficulty Starting the Engine: A faulty fuel injector can also make it difficult to start the engine. This is because the engine may not be getting enough fuel to start properly.
- Engine Stalling: In some cases, a faulty fuel injector can cause the engine to stall while driving. This can be dangerous, especially if it happens at high speeds.
If you experience any of these symptoms, it is important to have your Nissan inspected by a qualified mechanic as soon as possible. Ignoring the P0204 code can lead to more serious problems with your engine and can even cause damage to other components. A mechanic will be able to diagnose the problem and recommend the necessary repairs to get your Nissan running smoothly again.
P0204 Code Nissan:
If you own a Nissan and have encountered the P0204 code, it means that there is an issue with the number 4 fuel injector circuit. This code is specific to Nissan vehicles and can be caused by a variety of factors. Here are some of the possible causes of the P0204 code:
- Faulty fuel injector: A faulty fuel injector can cause the P0204 code to appear. This can happen if the injector is clogged, damaged, or not functioning properly.
- Wiring issues: Wiring problems can also cause the P0204 code. This can happen if there is a short circuit or an open circuit in the wiring that connects the fuel injector to the engine control module (ECM).
- ECM issues: If the ECM is not functioning properly, it can cause the P0204 code to appear. This can happen if there is a problem with the ECM’s circuitry or if the ECM is not receiving the correct signals from the fuel injector.
- Fuel system issues: Problems with the fuel system can also cause the P0204 code. This can happen if there is a problem with the fuel pressure, fuel pump, or fuel filter.

In some cases, a simple fix such as replacing a faulty fuse or cleaning the fuel injector may be all that is needed to resolve the issue. Whatever the cause, it is important to address the P0204 code as soon as possible to prevent further damage to your vehicle.
Fixes for P0204 Code Nissan
The P0204 code in Nissan indicates that there is an issue with the number 4 fuel injector circuit. This can cause a variety of problems, including reduced engine performance, increased emissions, and even engine damage if left untreated. Fortunately, there are several fixes available for this issue.
1. Check the Fuel Injector
The first step in fixing the P0204 code is to check the fuel injector itself. This involves removing the injector and inspecting it for any signs of damage or wear. If the injector is damaged, it will need to be replaced.
2. Check the Wiring
If the fuel injector appears to be in good condition, the next step is to check the wiring that connects it to the engine control module (ECM). This wiring can become damaged or corroded over time, which can cause the P0204 code to appear. If any issues are found with the wiring, it will need to be repaired or replaced.
3. Check the ECM
If both the fuel injector and wiring appear to be in good condition, the issue may be with the ECM itself. The ECM is responsible for controlling the fuel injector, so if it is malfunctioning, it can cause the P0204 code to appear. In this case, the ECM will need to be replaced.
4. Clean the Fuel Injector
In some cases, the fuel injector may simply be dirty or clogged. This can cause it to malfunction and trigger the P0204 code. Cleaning the fuel injector can often resolve this issue and restore proper engine performance.
5. Replace the Fuel Filter
A clogged fuel filter can also cause issues with the fuel injector and trigger the P0204 code. If the fuel filter is dirty or clogged, it will need to be replaced to restore proper fuel flow to the engine.
In conclusion, the P0204 code in Nissan can be caused by a variety of issues, including a damaged fuel injector, faulty wiring, a malfunctioning ECM, a dirty fuel injector, or a clogged fuel filter. By following the steps outlined above, you can diagnose and fix the issue, restoring proper engine performance and avoiding further damage.
