What does code P241F mean?

Q: What does code P241F mean?

EGR Cooler B Efficiency Below Threshold. P241F indicates that the powertrain control module has detected the exhaust gas recirculation cooler is not reducing exhaust gas temperatures as effectively as expected, based on temperature sensor readings across the cooler. The computer compares the temperature drop across the cooler to a modeled threshold and sets this code when the efficiency falls below the calibrated limit.
