P2AE0 Code: Intake Air O2 Sensor Pumping Current Trim Circuit Open Bank 1

What the code tells you

A diagnostic trouble code identifies a condition detected by a controller. It does not identify a failed part by itself; confirm the definition for the vehicle and controller involved.

Before diagnosis

Record the VIN, engine, symptoms, all stored codes and freeze-frame data before clearing faults. Follow the manufacturer’s test procedure. If there is overheating, loss of oil pressure, severe misfire or unsafe drivability, stop safely and arrange professional assistance.

Commercial-vehicle applicability

An OBD-II code is not a substitute for a heavy-duty SPN/FMI fault definition. Identify the engine and reporting controller; use the correct service information for that configuration.

P2AE0 means: Intake Air O2 Sensor Pumping Current Trim Circuit Open Bank 1. Intake Air oxygen Sensor Pumping Current Trim Circuit Open Bank 1. The computer sees a broken circuit — check for a damaged wire, loose connector, or failed part.
