Error code P1275 on a 2001 Honda Passport typically indicates an issue with the throttle position sensor (TPS) or its circuit. To fix it, first inspect the TPS and its wiring for any damage or loose connections. If everything looks fine, you may need to test the TPS's voltage output and replace it if it’s faulty. Finally, clear the error code with an OBD-II scanner and perform a test drive to ensure the issue is resolved.
