ON±VEHICLE INSPECTION
1. INSPECT AIR±FUEL RATIO COMPENSATION SYS-
TEM
HINT:
You can also check the system by choosing ºDATA MONITOR/
O
2 SENSOR OUTPUT VOLTAGEº on the monitor of the hand±
held tester.
(a) Connect the hand±held tester to the terminals 21 (OX1B)
and 7 (E1) and to terminals 23 (OX1A) and 7 (E1) of the
ECM.
CAUTION:
Connect test leads from the back side of the connector with
the ECM connected.
(b) Warm up the heated oxygen sensor with the engine
speed at 2,500 rpm for approximately 2 minutes.
(c) Confirm that the voltage varies output between 0V to 1V
with the engine speed at 2,500 rpm.
OK:
The voltage output varies more than 8 times in 10 se-
conds.
CAUTION:

Perform the check immediately after the warming up.

If the voltage variation could not be verified, warm up
the heated oxygen sensor again.
2. INSPECT FUEL CUT OFF RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating sounds.
(c) Check that injector operating sounds stops momentarily and then resumes when the throttle lever is
released.
3. INSPECT EVAPORATIVE EMISSION CONTROL SYS-
TEM
(a) After starting the engine, disconnect the vacuum hose
shown in the illustration.
(b) Check if vacuum occurs at the VSV port when choosing
ºACTIVE TESTº and ºPURGE VSVº according to the dis-
play on hand±held tester.
(c) Finish ºACTIVE TESTº, then reconnect the vacuum.
(d) After entering to ºECU DATA MONITORº on the hand±
held tester, choose ºPURGE VSVº to check the operation
of the purge VSV.
(e) After driving the vehicle with a warm engine, confirm that
the VSV turns from off to on.
