Note

•  Perform the following test only when directed.

Visual Inspection

1.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)

2.  Remove the boost sensor. (See COMMON RAIL REMOVAL/INSTALLATION [MZR-CD 2.2].)

3.  Visually inspect the boost sensor for the following:

•  Damage, cracks, soiling

•  Rusted sensor terminal

•  Bent sensor terminal

―  If the boost sensor is normal, then go to the next step.

―  If there is any malfunction, repair or replace the boost sensor. (See COMMON RAIL REMOVAL/INSTALLATION [MZR-CD 2.2].)

4.  Inspect the vacuum hose for improper routing, kinks or leakage.

•  If there is any malfunction, repair or replace suspected hose.
