Decoding the Language of Your S2000

Your S2000 speaks through a language of codes delivered via the OBD2 port. These codes, starting with a letter and followed by four digits, might seem cryptic at first, but they hold valuable information. For example, a “P” code refers to the powertrain, “B” to the body, “C” to the chassis, and “U” to network and communication systems.

Essential S2000 OBD2 Data Points

While countless data points can be accessed, certain ones are particularly beneficial for S2000 owners:

• Engine RPM: Real-time engine speed, useful for monitoring performance and identifying potential issues.
• Coolant Temperature: Crucial for preventing overheating and diagnosing cooling system problems.
• Intake Air Temperature: Influences fuel-air mixture and can indicate potential intake issues.
• Oxygen Sensor Readings: Vital for monitoring emissions efficiency and fuel economy.
• Short-Term & Long-Term Fuel Trim: Indicate how the engine is adjusting the fuel-air mixture. Deviations from the norm might point to vacuum leaks or sensor problems.
