You’re driving down the Pacific Coast Highway, the California sun warming your face, your favorite playlist filling the Infiniti with sound. Suddenly, a light on your dashboard flashes – the dreaded “Check Engine” light. Your heart sinks. What does it mean? Is it something serious? The experience is unsettlingly familiar to many Infiniti owners. The key to deciphering these warning signals lies in understanding Infiniti OBD codes.
Deciphering the Language of Your Infiniti
OBD, or On-Board Diagnostics, is essentially your Infiniti’s internal communication system. It uses a standardized set of codes, known as OBD-II codes, to signal malfunctions within the vehicle’s engine and emission control systems.
Think of OBD codes like a mechanic’s shorthand. Each code corresponds to a specific issue, providing a starting point for diagnosis and repair.
For instance, a code “P0101” indicates a problem with the Mass Air Flow (MAF) sensor, a critical component affecting engine performance and fuel efficiency. Ignoring such codes could lead to decreased fuel economy, increased emissions, or even engine damage in the long run.

The Value of Understanding OBD Codes
While a visit to a certified Infiniti technician is recommended for a comprehensive diagnosis, understanding basic OBD codes can empower you as a car owner.
Imagine being able to identify a minor issue like a loose gas cap (often indicated by code P0440) before it escalates into a more significant problem. This knowledge can save you time, money, and unnecessary stress in the long run.
Unmasking Common Infiniti OBD Codes
Infiniti vehicles, known for their luxury and performance, are not immune to the occasional hiccup. Let’s delve into some commonly encountered OBD codes in Infiniti models:
Engine Performance
-
P0300 – Random/Multiple Cylinder Misfire Detected: This code suggests a problem with the engine’s combustion process, potentially caused by faulty spark plugs, ignition coils, or fuel injectors.
-
P0171 – System Too Lean (Bank 1): This code indicates that the engine is receiving too much air compared to fuel, often attributed to issues with the MAF sensor, oxygen sensors, or vacuum leaks.
Emissions Control
-
P0420 – Catalyst System Efficiency Below Threshold (Bank 1): This code suggests a problem with the catalytic converter’s ability to reduce harmful emissions, potentially requiring replacement.
-
P0442 – Evaporative Emission Control System Leak Detected (Small Leak): This commonly encountered code often points to a minor issue like a loose gas cap, a faulty vent valve, or a small leak in the EVAP system.

Beyond the Codes: Expert Insights
“Understanding OBD codes is like having a basic understanding of your car’s language,” says Michael Thompson, a veteran Infiniti technician in Austin, Texas. “It allows you to have a more informed conversation with your mechanic and can potentially save you from unnecessary repairs.”
Thompson emphasizes that while OBD codes offer valuable clues, they shouldn’t be solely relied upon for self-diagnosis. “A professional diagnosis using advanced scan tools and experience is crucial for accurate troubleshooting and repair,” he adds.
