INSPECTION
1. INSPECT VACUUM REGULATING VALVE ASSY
(a) Inspect E±VRV for open circuit (1) Using an ohmmeter, measure resistance betweenthe terminals.
Resistance:
10 to 14
at 20
C (68
F)
(b) Inspect E±VRV for ground (1) Using an ohmmeter, check that there is no continu-ity between each terminal and the body.
Specified condition : No continuity
(c) Inspect E±VRV for air tightness (1) Apply vacuum to the vacuum output port. Checkthat the needle of vacuum pump indicates an in-
crease of 66.7 kPa (500 mmHg, 19.7 in.Hg) or
more.
If the air tightness is not as specified, replace the E±VRV.
(d) Inspect E±VRV operation (1) Apply about 4 dry batteries of 1.5V in series.
(2) Check that the need does not move when vacuumis applied to the vacuum outlet port.
If operation is not as specified, replace the E±VRV.

4. INSPECT VACUUM SWITCHING VALVE ASSY NO.1
(a) Inspect VSV for open circuit.
(1) Using an ohmmeter, measure resistance between
the terminals.
Resistance: 26 to 30
at 20
C (68
F)
If the resistance is not as specified, replace the VSV.
(b) Inspect the VSV for ground. (1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation. (1) Check that air flows with a little difficulty from port Eto port F.
(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
5. INSPECT AIR FUEL RATIO SENSOR
