The Foxwell NT510 is a powerful and versatile OBD2 diagnostic scanner that can perform a wide range of functions, including crankshaft relearn procedures. This comprehensive guide will delve into the intricacies of using the Foxwell NT510 for crankshaft relearn, equipping both DIY enthusiasts and seasoned professionals with the knowledge to tackle this task confidently.
Understanding Crankshaft Relearn
Before diving into the how-to, it’s crucial to understand what crankshaft relearn entails and why it’s essential. In essence, crankshaft relearn is a procedure that synchronizes the crankshaft’s position with the camshaft’s position, which is relayed to the engine control unit (ECU). This synchronization is vital for the ECU to calculate fuel injection timing and ignition timing accurately.
Why is this important? Imagine an orchestra where instruments are slightly out of sync. The music wouldn’t be harmonious, right? Similarly, if your crankshaft and camshaft positions aren’t correctly learned by the ECU, it can lead to a range of performance issues:
- Rough idling: The engine might vibrate excessively when the vehicle is stationary.
- Poor fuel economy: Inaccurate fuel injection timing can result in wasted fuel.
- Difficulty starting: The engine might crank for longer than usual or hesitate before starting.
- Check Engine Light: The dreaded “Check Engine” light might illuminate on your dashboard.
When Do You Need a Crankshaft Relearn?
Crankshaft relearn is typically required when:
- Replacing the crankshaft position sensor: This sensor plays a pivotal role in relaying crankshaft position information to the ECU.
- Replacing the timing chain or belt: These components are responsible for maintaining the synchronization between the crankshaft and camshaft.
- Disconnecting the battery for extended periods: While not always necessary, disconnecting the battery for long durations can sometimes cause the ECU to lose its crankshaft position data.
Performing Crankshaft Relearn with Foxwell NT510: A Step-by-Step Guide
The Foxwell NT510 simplifies the crankshaft relearn procedure, making it accessible even for those who aren’t seasoned mechanics. Here’s a step-by-step guide:
- Connect the Foxwell NT510: Plug the scanner into your vehicle’s OBD2 port, which is typically located under the dashboard on the driver’s side.
- Turn on the ignition: Switch the ignition to the “on” position but don’t start the engine.
- Access the software: Navigate to the “Special Functions” menu on the Foxwell NT510.
- Select “Crankshaft Position Sensor Relearn”: The specific wording might vary slightly depending on your vehicle make and model.
- Follow the on-screen prompts: The Foxwell NT510 will guide you through the relearn procedure. This typically involves clearing the old crankshaft position data and initiating a learning cycle where the ECU learns the new crankshaft position.
Important Considerations:
- Vehicle Specific Procedures: While the general steps remain consistent, always refer to your vehicle’s repair manual for any model-specific instructions or precautions.
- Safety First: When working on your vehicle, prioritize safety. Ensure the parking brake is engaged, the transmission is in “Park” (or “Neutral” for manual transmissions), and the engine is cool to prevent burns.

Common Questions About Crankshaft Relearn
- Q: How long does a crankshaft relearn procedure take?
- A: The duration can vary, but it typically takes around 15-30 minutes to complete.
- Q: Can I drive my car if the crankshaft position sensor needs to be relearned?
- A: While it’s technically possible to drive for short distances, it’s not recommended. Driving with an unsynchronized crankshaft can lead to reduced performance, poor fuel economy, and potential damage to your engine.
- Q: Is crankshaft relearn the same as resetting the ECU?
- A: No, they are distinct procedures. Crankshaft relearn specifically focuses on synchronizing the crankshaft position. Resetting the ECU, on the other hand, involves clearing all learned data from the ECU, including fuel trims, idle speed settings, and more.
