Implications for Vehicle Performance and Emissions

The P1260 code primarily affects the vehicle’s starting and operation.

While this code doesn’t directly impact emissions, the inability to start or run the vehicle properly can indirectly affect overall performance and fuel efficiency.

Diagnosing and Fixing Ford P1260

Diagnosing the Issue

  1. Verify the code: Use an OBD-II scanner to confirm the P1260 code is present.
  2. Check the battery: Low battery voltage can sometimes trigger this code.
  3. Inspect the key and transponder: Ensure the key is functioning correctly and the transponder chip is intact.
  4. Examine the ignition switch: A faulty ignition switch can cause communication issues with the PATS system.
  5. Check for wiring issues: Look for any damaged or corroded wiring in the PATS system.
  6. Scan for additional codes: Other related codes may provide more insight into the root cause.
  7. Consult a professional: If the issue persists, it’s best to consult a Ford specialist or dealership.
