P007D – Charge Air Cooler Temperature Sensor Circuit High Bank 1

P007D Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P007D Possible Causes

Damaged Turbocharger Boost Pressure (TCBP)/Charge Air Cooler Temperature (CACT) sensor,CACT circuit open or short to voltage,SIGRTN circuit open,Output from the charge air cooler (CAC) is colder than the calibrated threshold

P007D Description

The Powertrain Control Module (PCM) continuously monitors the Charge Air Cooler Temperature (CACT) circuit for concerns. The test fails when the temperature is lower than the calibrated value for the sensor or an open or short to voltage is detected in the circuit.
