CAUSE

There are currently 3 known potential causes under investigation: The charge air coolant pump, a PCM logic concern and/or sensor defect.

ACTION

NOTE: DTC P007B-00 is named: "Charge Air Cooler Temperature Sensor Circuit Range/Performance"

The sensor which this DTC relates to in TOPIx is the 'Manifold Absolute Pressure and Temperature (MAPT) sensor.

It is not to be confused with the 'Charged Air Temperature sensor'.

Details of the different sensors can be found in the following section of TOPIx under the 'Description and Operation' heading: 303-14B: Electronic Engine Controls - V6 S/C 3.0L Petrol

Follow the checklist items as recommended by the DTC actions found in the workshop manual or through SDD. In addition to the recommended actions, also check 'Charge air coolant pump' operation during and after engine start. Take care to listen for the pump running over the engine noise.

The location of the pump is shown in the following section of TOPIx under the 'Description and Operation' heading of: 303-03D: Supercharger Cooling - V6 S/C 3.0L Petrol

If there is no issue identified during the above, please raise a TA and prepare results for the following checks to add to the TA:

Check the wiring connector from relay to pump for damage to the connector housings or terminals
Check for short to ground or short to battery feed
Note the results from the check of 'Charge air coolant pump' operation during and after engine start
Check the label for the 'Charge air coolant pump'. Image of pump and required label information can be found in file attachment. Record if part number is shown as 'EX53'

Start drive from between 40°C and 60°C (104°F and 140°F) coolant 1 (ECT1)
Light steady gas pedal inputs up to 30MPH / 50KPH, hold for a minimum of 5 seconds
