About P011D

P011D 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 P011D 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 P011D 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 fault code P011D is activated when the Engine Control Module (ECM) detects a significant mismatch between the signals from the intercooler temperature sensor and the intake air temperature sensor for Bank 2. This condition indicates that the temperatures measured by these two sensors, which typically should display related or consistent readings, are showing a substantial difference. Such a mismatch could be indicative of an issue with one of the sensors, problems in their circuits, or real differences in temperature conditions within the intake or intercooling systems.
