Q: What does code P28F7 mean?

Exhaust Pressure Too High Bank 1. P28F7 indicates that the powertrain control module has detected exhaust pressure on bank 1 that is higher than the expected range for the current operating conditions. The computer compares the bank 1 exhaust pressure sensor signal against a modeled value, and when the measured pressure exceeds the threshold for a calibrated time, it stores this code and may illuminate the warning light.
