IMT Vacuum Solenoid Valve Inspection

WARNING: If vacuum is applied using your mouth, there is a risk of inhaling harmful fuel vapor.
Be sure to use a hand vacuum pump to apply vacuum.

NOTE: If too high a vacuum is applied, the IMT vacuum solenoid valve may be damaged. Do not exceed a vacuum of -86 kPa (-12.47 psi).

With ignition switch turned OFF, disconnect connector and vacuum hoses from IMT vacuum solenoid valve.
Remove IMT vacuum solenoid valve.
Check resistance between two terminals of IMT vacuum solenoid valve connector.
If faulty condition is found, replace IMT vacuum solenoid valve.

Check IMT vacuum solenoid valve operation as follows.
If faulty condition is found, replace IMT vacuum solenoid valve.
1. Install special tool and vacuum hose (2) to IMT vacuum solenoid valve (1).
  Special Tool
  
  (A): 09917-47011
2. Operate the special tool and check that vacuum of -60 kPa (-0.6 kgf/cm² , -8.7 psi, -0.6 bar) can be applied to IMT vacuum solenoid valve when 12 V battery is not connected to IMT vacuum solenoid valve terminals.
3. Operate the special tool and check that no vacuum can be applied to IMT vacuum solenoid valve when 12 V battery is connected to IMT vacuum solenoid valve terminals.
