The P1170 code on a 1999 Mazda Protege typically indicates an issue with the fuel system, specifically related to the fuel pressure sensor or the fuel system's performance. To fix this code, start by checking the fuel pressure and ensuring it meets specifications. Inspect the wiring and connectors to the fuel pressure sensor for any damage or corrosion. If these components are in good condition, consider replacing the fuel pressure sensor itself to resolve the issue.
