Inspect the crankcase ventilation tube at the rear air intake system connection for a partial disconnect. If the crankcase ventilation tube is not disconnected and no concern is identified after performing Powertrain Control and Emission Diagnosis \(PC/ED\) Manual pinpoint test HG, clear the DTC using the appropriate Ford scan tool and return the vehicle to the customer.
