Vehicle applicability: This diagnostic supplement covers multiple Ford vehicles and engines. Follow the application named in the source below. Some references apply to vehicles other than Mustang.
• Command the RPM PID to the maximum RPM.
• Record the TCBP PID reading.
• Command the TURBO_BPASS and the TURBO_BPASS_2 PIDs ON and record the TCBP PID reading.
Does the TCBP PID reading decrease when the bypass valves are commanded ON?
Yes | No |
|---|---|
GO to HN15 . | For Escape/Kuga 2.0L, Fiesta 1.0L, Focus 2.0L, Focus 2.3L, Fusion 2.0L, MKC, MKT 2.0L, MKZ 2.0L, and Taurus 2.0L, GO to HN19 . For all others, INSTALL a new TCBY solenoid. REFER to the Workshop Manual Section 303- 14, Electronic Engine Controls. Clear the PCM DTCs. REPEAT the self-test. |
HN15 CHECK WASTEGATE OPERATION
Note: For vehicles without the RPM command PID, use the accelerator pedal to hold the engine RPM at approximately 2,000 RPM.
• Ignition ON, engine running.
• Access the PCM and control the TURBO_BPASS (MODE) PID.
• Access the PCM and control the TURBO_BPASS_2 (MODE) PID.
• Command the TURBO_BPASS PID and the TURBO_BPASS_2 PID to OFF.
• Access the PCM and control the TURBO_WGATE (PER) PID.
• Command the TURBO_WGATE PID duty cycle to 100% (Edge, Explorer 2.3L, F-150 2.7L, MKX) or 0% (all others).
• Access the PCM and monitor the TCBP (PRESS) PID.
• Access the PCM and control the RPM (RPM) PID.
• Command the RPM PID to the maximum RPM.
• Record the TCBP PID reading.
• Command the TURBO_WGATE PID duty cycle to 0% (Edge, Explorer 2.3L, F-150 2.7L, MKX) or 100% (all others) and record the TCBP PID reading.
Does the TCBP PID reading increase from the initial recorded value?
Yes | No |
