Diagnostic tool & codes

[lobs84]

Hi everyone.
I have just purchased a diagnostic tool via eBay. While it comes with a book full of codes and what they mean I have a few that I have no idea what the mean or how to fix them.
1. Long term fuel trim system too lean
2. Evaporative emission control system
3. 17705. I don't have an explanation for this code.

Is there anyone who would know what these mean and/or how to fix them?
Thanks in advance.
Will.

Possible Symptoms
• Malfunction Indicator Light (MIL) ON
• Power Loss

Possible Causes
• Leaking Hoses and/or Pipes between Components
• Boost Pressure Control Valve (N249) faulty
• Diverter Valve faulty
• Throttle Body dirty

Possible Solutions
• Check Hoses and Pipes between Components
• Check / Replace Boost Pressure Control Valve (N249)
• Check / Replace Diverter Valve

Special Notes
• Did anyone install an extra (wrong) dump valve?
• When found in the NAR 2.0T (BPY) check RVUTB: 01-09-03 or 2018919 for updated Crankcase Breather Valve
• If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idle.
