Q: What does code P2AAD mean?

Diesel Fuel Presence Sensor Range/Performance. P2AAD indicates that the powertrain control module has detected an out-of-range or performance fault in the diesel fuel presence sensor circuit, which is used to verify that the fuel being burned is actually diesel and not a contaminant such as gasoline or water. The computer compares the sensor signal against expected values and sets this code when the reading falls outside the normal operating window or behaves erratically.
