2001 Nissan Altima EC 0106 Code: Diagnosis & Possible Causes in North America

Model: 2001 Nissan Altima Fault Code: P0106 Posted: 2018-12-02 15:29

A 2001 Nissan Altima 4-cylinder, 4-door sedan (SE trim, 4-wheel disc brakes) is exhibiting an EC 0106 diagnostic code when scanned using an aftermarket OBD-II tool. The official Engine Control Module service manual for this model year does not list the EC 0106 code; the closest referenced code is EC 0105. Further, the 'Engine Control Component Parts Location' diagram (pages EC13 and EC14) in the manual does not include a Manifold Absolute Pressure (MAP) sensor, which raises questions about how this system is implemented in the vehicle. The generic OBD-II code database lists: - P0105: Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction - P0106: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem Given that EC 0106 is not officially documented in the service manual, users are seeking clarification on whether this code corresponds to a known system function and what the most likely causes could be. Is EC 0106 a regional or tool-specific variation? What does it indicate for a 2001 Nissan Altima in North America?

Have you tried scanning the vehicle with a different OBD-II scanner? The EC prefix is commonly seen in European or third-world regions. Confirming whether this code appears on standard North American OBD-II systems may help clarify its validity.

I am located in North Carolina and purchased this vehicle used approximately five years ago. It has been maintained locally with no major repairs.

The EC prefix is indeed common outside North America. I've lived in Jacksonville, Elizabeth City, and Asheville—always a good reminder of how regional differences affect diagnostics. Many auto parts stores offer free OBD-II scans (e.g., AutoZone, Advance Auto Parts, O'Reilly). While they may try to sell parts afterward, it's worth getting a scan to confirm the code. If you see P0106 or similar, that would point toward MAP sensor issues or circuit faults.

The VIN confirms this vehicle was manufactured in Smyrna, Tennessee, USA—solidly within North American production. This supports the idea that the EC code may be a misreading or tool-specific issue rather than an official OBD-II fault.

Many auto parts stores offer free OBD-II scans—this can be a reliable way to verify codes without cost. Just ensure you're using a trusted scanner and cross-check results with multiple tools if possible.
