IMT Vacuum Tank

Check for outside of IMT vacuum tank visually.
Disconnect vacuum hoses from intake manifold and IMT vacuum solenoid valve.
Check for vacuum passage of IMT vacuum tank as follows by using vacuum pump.
1. When applying vacuum (- 53 kPa (- 7.69 psi) to - 67 kPa (-9.72 psi)) to hose (1), vacuum is maintained (there is no leakage): [A]
2. When applying vacuum to hose (2), vacuum is not maintained: [B]
  If check result is not described, replace IMT vacuum tank assembly.
