About P00A6

P00A6 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 P00A6 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; 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 P00A6 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 P00A6 fault code is set when the Engine Control Module (ECM) detects that the signal from the second Intake Air Temperature (IAT) sensor in Bank 2 is out of the expected range or performing abnormally. This sensor measures the temperature of the air entering the engine's intake system and is crucial for the ECM to calculate air density and adjust the air-fuel mixture, ignition timing, and other engine parameters for optimal performance and efficiency. In engines with two banks, such as V6 or V8 engines, Bank 2 refers to the second group of cylinders. A signal that is out of range or shows ...
