Understanding 1996 Acura Integra OBD2 Codes

OBD2 codes are alphanumeric codes that represent specific malfunctions detected by your Integra’s onboard computer. These codes are standardized across makes and models, making diagnostics more streamlined.

Here’s a breakdown of the code structure:

• The first character: Indicates the system related to the fault. For instance, “P” stands for Powertrain, referring to the engine, transmission, or emissions systems.
• The second character: This digit specifies whether it’s a generic (0) or manufacturer-specific code (1).
• The third character: This letter pinpoints the specific system within the broader category (e.g., “0” for fuel and air metering, “1” for fuel and air metering injection system).
• The last two characters: These digits specify the exact problem within the system identified by the first three characters.

For example, a P0302 code indicates a misfire detected in cylinder number 2.

Common 1996 Acura Integra OBD2 Codes

While numerous codes can be triggered, some are more prevalent in the 1996 Integra:

• P0420: Catalyst System Efficiency Below Threshold (Bank 1) – This code often signifies a failing catalytic converter.
• P0135: O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1) – Indicates a problem with the oxygen sensor’s heating element, crucial for accurate readings.
• P0300: Random/Multiple Cylinder Misfire Detected – As the name implies, this code indicates engine misfires, potentially due to spark plugs, ignition coils, or fuel delivery issues.
• P0171: System Too Lean (Bank 1) – Suggests the engine is running lean, meaning there’s too much air compared to fuel in the air-fuel mixture.
• P0102: Mass Air Flow (MAF) Sensor Circuit Low Input – This code points to a problem with the MAF sensor, which measures the amount of air entering the engine.
