Q: What does code P2AE5 mean?

Intake Air O2 Sensor Pumping Current Circuit High Bank 1. P2AE5 indicates that the powertrain control module has detected an abnormally high current in the pumping circuit of the intake air oxygen sensor on bank 1. This sensor is a wide-band air/fuel ratio sensor that uses an ion pump to measure oxygen concentration, and the high current reading tells the module the circuit is drawing more current than expected.
