Diagnostic Trouble Code (DTC) Charts and Descriptions
P007B - Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1) (Continued) Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DN.
P007C - Charge Air Cooler Temperature Sensor Circuit Low (Bank 1)
Description: This DTC sets when the charge air cooler temperature (CACT) is greater than a calibrated value or a short to
ground is detected in the CACT circuit.
Possible Causes: • Damaged charge air cooler temperature (CACT) sensor
• CACT circuit short to ground
• VPWR circuit open
• Low airflow through the charge air cooler (CAC)
• Damaged harness connector
• Damaged harness
Diagnostic Aids: Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to
contact with other components. This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DN.
P007D - Charge Air Cooler Temperature Sensor Circuit High (Bank 1)
Description: This DTC sets when the charge air cooler temperature (CACT) is lower than a calibrated value or an open or
short to voltage is detected in the CACT circuit.
Possible Causes: • Damaged charge air cooler temperature (CACT) sensor
• CACT circuit open
• CACT circuit short to voltage
• SIGRTN circuit open
• Output from the charge air cooler (CAC) is colder than the calibrated threshold
Diagnostic Aids: Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to
contact with other components. This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.

All GO to Pinpoint Test DN.
P0087 - Fuel Rail/System Pressure - Too Low
For Mustang, 5.2L
Description: This DTC sets when the fuel rail pressure requested by the PCM is greater than the fuel rail pressure delivered,
by more than a calibrated threshold for greater than a calibrated length of time.
Possible Causes: • Low fuel pressure
• Low or no fuel
• FRP circuit concerns
• Damaged FRP sensor
Diagnostic Aids:
For All Others
Description: The PCM regulates the fuel rail pressure by controlling the fuel volume regulator. This DTC sets when the PCM
is no longer capable of maintaining the fuel pressure within the calibrated parameters.
Possible Causes: • Fuel filter plugged or dirty
• Fuel supply line restricted
• Damaged fuel pump module
• Damaged fuel injection pump
Diagnostic Aids: Diagnose any FRP and FVR circuit DTCs first.
