Is your Nissan’s check engine light illuminated? Understanding the location of the OBD2 sensor in your 2019 Nissan Murano is crucial for diagnosing potential issues. This guide will help you locate the OBD2 port and understand common trouble codes.
The OBD2 (On-Board Diagnostics) system in your 2019 Nissan Murano monitors various vehicle components, detecting malfunctions and triggering diagnostic trouble codes (DTCs). These codes can be read using an OBD2 scanner, providing valuable insights into the nature of the problem. Locating the OBD2 port is the first step in this diagnostic process.
Locating the OBD2 Port in Your 2019 Nissan Murano
In most 2019 Nissan Muranos, the OBD2 port is located under the dashboard, on the driver’s side, near the steering column. It’s typically a 16-pin female connector. You might need to look up under the dash, sometimes near the fuse box or above the pedals.
Once you’ve located the port, you can connect an OBD2 scanner to retrieve the diagnostic trouble codes.
Understanding 2019 Nissan Murano OBD2 Trouble Codes

This table represents a small sample of possible codes. There are hundreds of potential OBD2 codes.
Using an OBD2 Scanner
An OBD2 scanner allows you to read the diagnostic trouble codes stored in your vehicle’s computer. These scanners range from simple code readers to advanced professional tools. After connecting the scanner to the OBD2 port, you can retrieve the codes and begin diagnosing the problem.
What if My Code Isn’t Listed?
If you encounter a code not listed here, or if you’re unsure about how to interpret the codes, consult a qualified mechanic or a Nissan dealership. Codes beginning with “P1” are often manufacturer-specific and may require specialized diagnostic equipment.
Need Professional Help?
Diagnosing and repairing car problems can be complex. If you’re uncomfortable working on your vehicle yourself, it’s always best to consult a professional. A qualified mechanic can accurately diagnose the issue and perform the necessary repairs.
