P2EAEReductant Injection Valve Circuit Range/Performance Bank 1 Unit 2

P2EAE indicates that the powertrain control module (PCM) has detected an out-of-range or performance issue with the reductant injection valve circuit for bank 1 unit 2, which is part of the selective catalytic reduction (SCR) system on a diesel engine. The PCM monitors the valve's electrical circuit and expects certain feedback or current draw when commanding the valve; when the signal falls outside the expected range or does not respond as commanded, this code is stored.
