Fault Family System: Powertrain (P-Codes) 23 SAE Codes

Charge Air Cooler Temp Circuit

Diagnostic & Technical Explanation

Code P007A (Charge Air Cooler Temperature Sensor Circuit Bank 1) sets when the ECM sees an open, shorted, or implausible signal from a charge air cooler air or coolant temperature sensor, or a correlation mismatch against a related intake air temperature signal. Root causes are a failed thermistor element, a corroded connector in the charge piping area, or a chafed harness run along the intercooler ducting.

These 23 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 23 times.
