Understanding OBD-II and Diagnostic Trouble Codes
Before we delve into Foxwell NT201 codes, it’s essential to grasp the basics of On-Board Diagnostics II (OBD-II). This standardized system, mandatory in vehicles manufactured since 1996, allows for communication between your car’s computer and external diagnostic tools like the Foxwell NT201.
When your car’s computer detects a problem within a system, it logs a Diagnostic Trouble Code (DTC) in its memory. These codes, often appearing as a combination of letters and numbers, act as clues pointing towards the potential source of the issue.

Deciphering Foxwell NT201 Codes
Each Foxwell NT201 code corresponds to a specific problem area within your car’s systems. While the NT201 provides a brief description of each code, a deeper understanding can help you pinpoint the issue more effectively. Let’s explore some common code categories:
- Powertrain Codes (P-Codes): These relate to the engine and transmission, often indicating problems with fuel/air metering, ignition, emissions, or the transmission itself.
- Chassis Codes (C-Codes): Covering issues related to mechanical components like the Anti-lock Braking System (ABS), steering, and suspension.
- Body Codes (B-Codes): Pointing to problems with body electronics such as power windows, airbags, or central locking.
- Network Communication Codes (U-Codes): Indicating faults in the communication network connecting various modules within the vehicle.
Foxwell NT201: Beyond Basic Code Reading
The Foxwell NT201 is more than just a code reader; it offers a range of advanced features:
- Live Data Stream: Provides real-time data from various sensors, allowing you to monitor engine performance, oxygen sensor readings, and more.
- Freeze Frame Data: Captures a snapshot of sensor readings at the time a fault code was stored, offering valuable clues for diagnosis.
- Component Testing: Allows you to activate certain components, such as solenoids or actuators, to verify their operation.

Common Foxwell NT201 Codes and Their Meanings
While the specific codes and their descriptions might differ slightly depending on the vehicle make and model, here are some frequently encountered codes:
- P0171: System Too Lean (Bank 1) – Often indicating a vacuum leak, faulty oxygen sensor, or fuel delivery problem.
- P0301: Cylinder 1 Misfire Detected – Could be caused by a faulty spark plug, ignition coil, injector, or a compression issue.
- C0242: Low Output Front Right Wheel Speed Sensor – Signaling a potential problem with the wheel speed sensor, wiring, or the ABS module itself.
- U0100: Lost Communication with Engine Control Module (ECM/PCM) – This critical code points towards a communication breakdown between the ECM/PCM and other modules, often requiring professional diagnosis.
