is maintained.
NOTEIf negative pressure is not normal, it can be assumed that there is amalfunction in the knock sensor circuit.(7) Turn off the ignition switch, and connect the connector of
the detonation sensor.
(8)Disconnect the (-) terminal of the battery for 10 seconds or
more.
NOTE
This erases the diagnosis memory of the detonation sensortrouble by disconnecting the detonation sensor connector.

VALVE INSPECTIONNllGGAA
(1) Operation check
Using a hand
vaccum pump, apply a negative pressure to
the solenoid valve nipple on which the white vacuum hose
is connected, and check air-tightness when the voltage is
applied to the solenoid valve terminal and when it i‘s releasedfrom the terminal.

AIR BYPASS VALVE INSPECTIONNllGHAA
(1) Remove the air bypass valve.
(2) Connect the hand vacuum pump to the nipple of the air
bypass valve.
(3) Apply a negative pressure of approx. 53.3 kPa (7.7 psi), andcheck operation of the valve. Also check that air tightness
is maintained.
Negative pressure
About 53.3 kPa (7.7 psi)
