About P00AE

P00AE is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P00AE is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P00AE is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P00AE fault code is set when the Engine Control Module (ECM) detects intermittent readings or signal disruptions from the first Intake Air Temperature (IAT) sensor in Bank 2. This sensor plays a key role in measuring the temperature of the air entering the engine's intake system, providing data crucial for the ECM to calculate air density. Accurate air density information is essential for the proper adjustment of the air-fuel mixture, ignition timing, and other engine management functions. In multi-cylinder engines divided into banks, such as V6 or V8 engines, Bank 2 typically refers to th...
