About P007C

P007C 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 P007C is stored, the module has detected a signal or supply voltage lower than the expected operating range; 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 P007C 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 P007C fault code is set when the Engine Control Module (ECM) detects a lower than expected voltage or signal from the Charge Air Cooler (CAC) temperature sensor, also known as the intercooler temperature sensor, in Bank 1. This sensor measures the temperature of the air after it passes through the intercooler in turbocharged or supercharged engines. The intercooler cools the compressed air from the turbocharger or supercharger before it enters the engine, thereby increasing its density and improving combustion efficiency. A low signal from the intercooler temperature sensor can indicate a ...
