About P007F

P007F 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 P007F 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 P007F 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

On twin turbocharged V configuration engines each cylinder bank has its own charge air cooler circuit and its own intercooler temperature sensor, both of which are negative temperature coefficient thermistors reporting charge air temperature to the Engine Control Module (ECM). Because the two banks share ambient conditions, the same intake path and broadly the same load, the ECM expects the two readings to track each other closely and uses the comparison as a rationality check on both sensors and on the charge cooling system itself. DTC P007F is set when the difference between the Bank 1 and B...
