Engine and Emission System Codes: Key Indicators of Performance
Your Nissan Altima’s check engine light can be a lifesaver. It tells you when your car needs attention. Engine and emission system codes often reveal critical issues. These codes, like a P0171 or P0420, are warnings from your Altima.
P0171: System Too Lean (Bank 1)
This code means your engine's air-fuel mixture is off. A lean mixture may cause poor performance or damage. Common causes include vacuum leaks or dirty fuel injectors. A quick check with a Nissan Altima engine scanner can pinpoint the problem.
P0420: Catalyst System Efficiency Below Threshold (Bank 1)
A P0420 code indicates trouble with your catalytic converter. This part helps reduce harmful emissions. Ignoring it can harm your car and the environment. When your Nissan Altima needs repair, this code often requires a professional fix.
P0300: Random/Multiple Cylinder Misfire Detected
If your engine is misfiring, you may feel it. The P0300 code means multiple cylinders aren’t firing properly. Check spark plugs or ignition coils to fix this issue. Use an engine scanner to find the exact problem before it gets worse.
Addressing these codes early keeps your Altima running smoothly. If you’re in Studio City, North Hollywood, or Encino, bring your car to Nissan of Van Nuys. Our experts are ready to decode the problem and keep you on the road.
Transmission Troubles: Codes That Demand Immediate Attention
Transmission problems are no small matter. If your Nissan Altima is showing signs of trouble, such as hesitation when shifting or strange noises, error codes may be to blame. These codes are crucial indicators that your Altima needs immediate attention. Thankfully, a Nissan Altima engine scanner can quickly reveal the issue. Catching transmission issues early can save you from costly repairs and potential breakdowns.
P0744: Torque Converter Clutch Circuit Intermittent
This code indicates an issue with the torque converter clutch (TCC). The TCC helps to lock the torque converter when the vehicle reaches certain speeds. When this system fails, your Altima may experience rough shifting or loss of power. If you see this error code, don’t ignore it. Low transmission fluid or electrical issues could be the cause. If you wait too long, further damage to the transmission is possible.
P0868: Transmission Fluid Pressure Low
The P0868 code points to low fluid pressure in your Altima’s transmission. Transmission fluid keeps all the moving parts lubricated. If the fluid level is low, it can lead to overheating and serious damage. You may notice poor shifting performance, strange noises, or slipping gears. If you see this code, check the fluid level and inspect for leaks. It’s crucial to act quickly before the issue worsens.
When your Nissan Altima check engine light comes on with these codes, it’s a clear sign that your transmission needs repair. Addressing these issues early can save you from expensive fixes down the road. Ignoring the problem may lead to a complete transmission failure.

Sensor-Related Codes: The Backbone of Modern Vehicles
In today’s advanced vehicles, sensors are the silent heroes behind smooth operation and optimal performance. Your Nissan Altima relies on a network of sensors to monitor key systems and make real-time adjustments. When a sensor fails, it throws everything off balance. That’s why the Nissan Altima check engine light is your first sign of trouble. These codes aren’t just alerts—they’re a call to action to protect your car.
P0101: Mass Airflow Sensor Range/Performance Issue
This error code points to a problem with the mass airflow sensor (MAF), a key component in managing your engine’s air-fuel mixture. When the MAF sensor isn’t working correctly, it may send inaccurate data about how much air is entering the engine. The result? Poor performance and reduced fuel efficiency. Common causes include dirt buildup, wiring issues, or sensor failure. A Nissan Altima engine scanner can quickly pinpoint this issue, making it easy to address. Cleaning or replacing the sensor is often all it takes to restore smooth operation.
P0113: Intake Air Temperature Sensor Circuit High Input
Your intake air temperature sensor ensures the engine knows how hot or cold the incoming air is. This information helps optimize fuel combustion. When this sensor malfunctions, your Altima might struggle with uneven performance or poor fuel economy. A damaged sensor or faulty wiring is often to blame. If this code appears, it’s time for your Altima to get the repair it needs before further issues arise.
Ignoring sensor issues can lead to bigger, costlier problems. These tiny components are critical to your car’s health and performance. If you’re driving through Studio City, North Hollywood, or Encino, and your Nissan Altima error codes pop up, don’t wait. Visit Nissan of Van Nuys for expert service. We’ll ensure your Altima’s sensors are in top shape, helping you avoid larger headaches down the road.
Brake and ABS System Codes: Ensuring Safe Stopping Power
When it comes to the safety of your Nissan Altima, the brake and ABS (Anti-lock Braking System) are crucial. They help you stop safely and maintain control, especially in adverse conditions like rain or snow. If there is an issue with these systems, your Nissan Altima check engine light may illuminate, signaling that something is wrong. Brake and ABS system codes are often key indicators that your Altima needs attention, and addressing these issues quickly is essential for your safety.
C0035: ABS Wheel Speed Sensor Malfunction
One of the most common brake and ABS system error codes is C0035, which points to a malfunction in the ABS wheel speed sensor. This sensor monitors the speed of each wheel and is responsible for adjusting braking power as needed. When it fails, the ABS system can no longer function correctly, making your Altima harder to control in slippery conditions. You might experience reduced braking effectiveness or a delay in the system’s response.
If the Nissan Altima check engine light comes on due to this error, it’s important not to ignore it. The sensor could be dirty, damaged, or have an electrical fault. A Nissan Altima engine scanner can help pinpoint the exact issue and determine if a simple cleaning or a replacement is necessary.
C1145: ABS Hydraulic Pressure Sensor Circuit
Another error code, C1145, signals a problem with the ABS hydraulic pressure sensor circuit. This sensor is essential for managing the hydraulic pressure used in the braking system. If the sensor is malfunctioning, it can cause problems with how the brakes respond. In some cases, the brakes may feel less effective, or you could notice that the ABS doesn’t kick in during an emergency stop.
This issue can lead to dangerous driving conditions, especially in wet or slippery areas. If your Altima’s brake performance is compromised, your safety could be at risk. The problem may be due to a faulty sensor or a wiring issue that needs to be addressed. A Nissan Altima engine scanner can help identify this issue, allowing for a faster diagnosis and repair.
C1163: ABS Sensor Circuit Malfunction
Another code you might encounter is C1163, which relates to an ABS sensor circuit malfunction. If there is a fault in the ABS sensor circuit, your Altima’s braking system might not work as intended. This could lead to issues such as the ABS system not activating in time or reduced stopping power when you need it most.
Your vehicle’s ABS system is designed to prevent wheel lock-up during hard braking, but it relies on a network of sensors to function properly. If a sensor in the system is malfunctioning, the safety of your Altima could be compromised. In this case, the best option is to get a Nissan Altima engine scanner diagnosis and seek professional repair services right away.
Why These Codes Matter
Ignoring these codes can lead to serious consequences. Brake and ABS issues are safety-related, and they directly impact your ability to stop quickly and safely. If your Altima’s Nissan Altima check engine light comes on due to brake or ABS system codes, take it seriously.
Having your Altima checked by a certified technician is the safest option. If you notice any warning signs such as reduced braking power, unusual noises, or the Nissan Altima check engine light appearing, it’s time to visit a professional. The sooner you act, the sooner you can restore your vehicle’s safety and performance.
If you suspect any brake or ABS issues in your Nissan Altima, don’t wait for them to get worse. Visit Nissan of Van Nuys, where we offer expert diagnostics and fast repairs. With our Nissan Altima engine scanner and certified technicians, we’ll ensure your Altima stops like it should—every time!
Body and Electrical Codes: Beyond the Basics
The body and electrical systems in your Nissan Altima handle more than just convenience features. They play a vital role in daily driving, ensuring safety and comfort. When issues arise, they can trigger error codes that may not seem urgent but deserve your attention. A Nissan Altima engine scanner is an essential tool for uncovering these problems before they escalate.
B2562: Front Left Door Lock/Unlock Switch Circuit Malfunction
This code indicates an issue with the left door lock/unlock switch. A faulty switch or damaged wiring often causes it. You might notice the door doesn’t lock or unlock as expected. While this might seem minor, it’s essential to repair it promptly. Left unchecked, it can lead to more significant electrical issues.
U1000: CAN Communication Line Malfunction
This error relates to the vehicle’s CAN (Controller Area Network) system. The CAN system connects key components of your Altima, allowing them to "talk" to one another. If this communication is disrupted, your vehicle’s systems may fail to work together. This can cause unpredictable issues, like the Nissan Altima check engine light turning on. A professional scan and repair are necessary to resolve this.
Ignoring body and electrical codes can lead to inconvenience and unexpected breakdowns. If your Nissan Altima needs repair, it’s time to act.

Battery and Charging System Codes: Powering Your Altima
The battery and charging system are the heart of your Nissan Altima’s electrical functions. They provide the power necessary to start your car and keep vital systems running. When something goes wrong, you may encounter error codes that indicate trouble. Catching these issues early can prevent larger problems down the road. A Nissan Altima engine scanner can quickly detect these codes and help you understand what needs attention.
P0562: System Voltage Low
This code signals that the system voltage in your Altima is lower than required. It often points to a weak battery or a malfunctioning alternator. If you notice dimming headlights, slow electrical accessories, or difficulty starting your Altima, this code may appear. While this issue can sometimes be minor, it’s best to take action. Ignoring it could leave your Altima unable to start when you need it most. Don’t risk being stranded – address this code early to avoid major repairs.
P0621: Generator Lamp Circuit Malfunction
The P0621 code indicates a problem in the alternator’s lamp control circuit. This can lead to charging issues, which affect the battery and other electrical components. Without proper charging, your battery may quickly drain, leaving you without power. If you see this code, it’s important to take action quickly. If ignored, you could find your Altima unable to start or experience erratic electrical behavior.
These battery and charging-related codes can also trigger the Nissan Altima check engine light, warning you of underlying issues. It’s essential to take these alerts seriously. A malfunctioning battery or alternator can leave you stranded or cause more serious electrical problems. If your Nissan Altima needs repair, don’t wait to address these codes.
