Is your Acura’s check engine light illuminated? Don’t panic. Modern vehicles like the Acura TL are equipped with sophisticated On-Board Diagnostic (OBD) systems. When your Acura detects a problem, it triggers a trouble code, which can be accessed using an OBD-II scanner. These codes are invaluable for pinpointing potential issues and guiding repairs.
This guide will help you understand Acura OBD2 codes, specifically focusing on how they relate to your Acura TL. While a diagnostic scan is the first step, understanding the potential meanings behind these codes can empower you to make informed decisions about your vehicle’s maintenance.

Decoding Common Acura TL OBD2 Code Categories
To better understand the table above, let’s categorize some common OBD2 codes you might see in your Acura TL:
Engine Performance Codes (P00XX – P03XX)
These codes often relate to issues affecting your Acura TL’s engine performance, including:
- P0010-P0014 (Variable Valve Timing): These codes indicate potential problems with the variable valve timing system, crucial for engine efficiency and power. Issues can range from low oil level to faulty solenoids or even timing chain problems.
- P0101-P0113 (Airflow Sensors): Codes in this range often point to problems with the Mass Air Flow (MAF) sensor or Intake Air Temperature (IAT) sensor. These sensors are vital for measuring the air entering the engine, and malfunctions can lead to incorrect fuel mixtures and poor performance. Vacuum leaks can also trigger P0101.
- P0128 (Coolant Thermostat): This code suggests your engine coolant is not reaching the expected temperature within a reasonable timeframe. A faulty thermostat is a common culprit, but other cooling system issues can also be responsible.
- P0135, P2A00-P2A04, P2237, P2238, P2251 (Oxygen Sensors): Oxygen sensors monitor the exhaust gases to ensure the engine is running efficiently. These codes can indicate sensor failures, exhaust leaks, or wiring problems affecting the sensor circuits.
- P0171 & P0174 (Lean Fuel System): These codes signal that the engine is running lean, meaning there’s too much air and not enough fuel in the mixture. Vacuum leaks, MAF sensor issues, or fuel delivery problems can cause lean conditions.
- P0200-P0205 (Fuel Injector Circuit): These codes indicate problems with the fuel injectors or their circuits. Faulty injectors can disrupt fuel delivery, leading to misfires and poor engine performance.
- P0300-P0304 (Misfire Codes): Misfire codes are among the most common. They indicate that one or more cylinders are not firing correctly. Causes can range from worn spark plugs and ignition components to vacuum leaks or engine mechanical problems.
Emission System Codes (P04XX)
These codes relate to your Acura TL’s emission control systems, designed to reduce harmful pollutants:
- P0401 (EGR System): This code suggests a problem with the Exhaust Gas Recirculation (EGR) system, which helps reduce NOx emissions. Carbon buildup or a faulty EGR valve are common causes.
- P0420 & P0430 (Catalytic Converter Efficiency): These codes indicate that the catalytic converter’s efficiency is below the required threshold. A failing catalytic converter, exhaust leaks, or engine misfires can trigger these codes.
- P0440, P0441, P0442, P0455 (EVAP System Leaks): These codes relate to leaks in the Evaporative Emission Control (EVAP) system, which prevents fuel vapors from escaping into the atmosphere. A loose or faulty fuel cap is often the simplest cause, but other components like hoses, valves, or the carbon canister can also be the source of leaks.
Transmission Codes (P07XX – P09XX, P27XX – P28XX)
These codes indicate issues within your Acura TL’s transmission system:
- P0700-P0730 (Transmission Performance): These codes can signal various transmission problems, including shift solenoid issues, fluid contamination, or valve body problems.
- P0705-P0706 (Transmission Range Sensor): These codes indicate problems with the transmission range sensor, which tells the computer what gear the transmission is in.
- P0720 (Output Speed Sensor): This code suggests a problem with the output speed sensor, which monitors the transmission’s output shaft speed.
- P0841-P0847, P0961, P2706, P2711, P2714, P2716, P2723, P2809, P2810, P2815 (Transmission Solenoid/Pressure): These codes often point to issues with transmission solenoids or pressure sensors that control gear shifting and transmission fluid pressure.
Hybrid/Electric Vehicle Codes (P0AXX – P0CXX, P3XXX)
For Acura TL models with hybrid powertrains (if applicable), these codes relate to the hybrid system components:
- P0A08, P0A0D, P0A0F, P0A7F, P0A80, P0B22, P0B24, P0B26, P0B28, P0B30, P0C00, P0C09, P0C11, P0C14, P0C15, P3000, P3100: These codes cover a wide range of potential problems within the hybrid system, including inverter/converter issues, battery problems, motor/generator faults, and coolant system leaks specific to hybrid components.
Chassis and Body Codes (B0XXX, C0XXX, U0XXX)
While “P” codes are powertrain related, other codes exist:
- B0081 (Airbag System): “B” codes are body-related. B0081 indicates a problem with the airbag system.
- C0040, U0001 (ABS/Wheel Speed Sensor): “C” codes are chassis-related. C0040 and U0001 can point to issues with wheel speed sensors or the Anti-lock Braking System (ABS).
- U0073, U0100, U0107, U0121 (Communication/CAN Bus): “U” codes are network communication related. These codes can indicate problems with the vehicle’s communication network (CAN bus) or control modules like the PCM or ABS module.
