The FIXD OBD2 scanner is a popular tool for diagnosing car problems, but does it work on a Porsche 911? This article will explore the Porsche 911 drive cycle and how it relates to using OBD2 scanners like FIXD to clear emission monitors. We’ll also address common questions and concerns about using OBD2 scanners on Porsche vehicles.
Understanding the Porsche 911 Drive Cycle
The Porsche 911, like all modern vehicles, utilizes an On-Board Diagnostics II (OBD2) system to monitor emissions and engine performance. To ensure accurate readings, specific drive cycles are required to “ready” or “complete” the vehicle’s emission monitors. These monitors track various components, including the catalytic converter, oxygen sensors, and evaporative emissions system.
A common reason for incomplete monitors is a recently cleared diagnostic trouble code (DTC) or a disconnected battery. Completing a drive cycle allows the OBD2 system to gather the necessary data to determine if the issue is truly resolved. Here’s a general outline of the Porsche 911 drive cycle:
- Preparation: Ensure your fuel tank is between ¼ and ¾ full.
- Step 1: Idle: Start the engine and let it idle for approximately 2.5 minutes. This allows the oxygen sensors to warm up and the ECU to perform initial diagnostics.
- Step 2: Acceleration and Steady Speed: Accelerate to 20-30 mph and maintain that speed for 3.5 minutes. Then, accelerate to 40-60 mph and maintain for 15 minutes.
- Step 3: Idle: Decelerate to a complete stop and idle for 3 minutes (in neutral for manual transmissions, in drive for automatics).
- Step 4: Repeat: Repeat steps 2 and 3.
Important Considerations: Do not exceed 3,000 RPM or 60 mph during the drive cycle. Perform the entire cycle without interruption, as partial completion will not set the monitors. Always prioritize safety when performing the drive cycle on public roads.
Using FIXD OBD2 on a Porsche 911
While FIXD can read and clear codes on a Porsche 911, its functionality may be limited compared to a professional-grade OBD2 scanner. FIXD can display which monitors are not ready, allowing you to track your progress through the drive cycle.
Some users have reported success using FIXD in conjunction with the Porsche 911 drive cycle to reset emission monitors. However, others have noted challenges, especially with specific monitors like the EVAP system.
Tips for Using FIXD and Completing the Drive Cycle
- Verify Compatibility: Ensure FIXD is compatible with your specific Porsche 911 model year.
- Follow Instructions Carefully: Adhere to the precise steps of the drive cycle. Minor deviations can prevent monitor completion.
- Patience is Key: Completing the drive cycle may require multiple attempts.
- Consider Alternatives: If you experience persistent difficulties, consult a Porsche specialist or use a more advanced OBD2 scanner. Alternative drive cycle procedures, such as driving at specific RPM ranges in certain gears, have also been reported by some Porsche owners.
Conclusion
FIXD OBD2 can work on a Porsche 911 to read codes and monitor readiness status. When combined with a properly executed drive cycle, it can potentially help reset emission monitors. However, results may vary depending on the specific model year and the monitor in question. Always prioritize safety when performing the drive cycle and consult a professional if you encounter persistent issues. Ultimately, utilizing FIXD alongside a thorough understanding of the Porsche 911 drive cycle can be valuable for basic diagnostics and maintenance.
