What does code P24FD mean?

Q: What does code P24FD mean?

Particulate Filter A Incorrect. P24FD indicates that the powertrain control module has detected an incorrect performance from particulate filter bank A, meaning the filter's measured restriction or efficiency does not match the expected values for the current operating conditions. The computer typically compares pressure differential readings across the filter with modeled exhaust flow to flag this fault when the values fall outside the calibrated range.
