Test drove vehicle and found no trouble indicators lit on dash upon entry. Inspected vehicle on hoist and scanned for codes. Found P2127- accelerator pedal position sensor 2 circuit low voltage. Inspected related circuits and connections and found no obvious faults. Performed pedal sweep while observing data on scan tool and found signal glitches at times, indicating a worn pedal sensor, which is part of the accelerator pedal assembly. Suggest replacing pedal assembly, clearing codes, and rechecking vehicle operation.

Road tested vehicle and scanned for codes. Found P0089- fuel pressure regulator performance, and P0191- fuel rail pressure sensor performance. These codes point to a possible high pressure fuel pump issue. After observing data on scan tool while operating vehicle found a difference between desired and actual fuel rail pressure, indicating a high pressure fuel pump issue. Also found the HP fuel pump making excess noise with engine running. Customer advised us the HP fuel pump was replaced elsewhere within the last 6 months. Recommend returning to service center that previously replaced the pump for further evaluation.
Found noise from HP fuel pump. Recommend removal and inspection of pump and camshaft surface which drives the pump.
