DTC codes / P2Axx · Hybrid propulsion / P2AED
P2AED indicates that the powertrain control module has detected an abnormally low current draw in the oxygen sensor pumping circuit for the bank 2 intake air oxygen sensor. This sensor, often a wideband or air-fuel ratio sensor, uses a pump cell to move oxygen ions and report the exhaust oxygen content to the computer. The code sets when the measured pumping current falls below the expected threshold for the current operating conditions.
