CAUTION:
Connect test leads from the back side of the connector with
the ECU 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 output varies 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 the injector operating sounds stops momentarily and then resumes that 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 hose.
(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 on to.

REPLACEMENT
HINT:

The installation is in the reverse order of the removal. However, when there is a special point concern-
ing the installation, it is indicated.

Use the same procedures on the RH side as on the LH side.

After removing the torsion bar, opening and closing door operation should be carried out while holding
the door with your hand in order to perform an accurate test by providing sliding resistance.

The RH side torsion bar is on the upper side and the LH side torsion bar is on the lower side, thus the
installation should be performed in the order of RH to LH and removal should be performed in the order
of LH to RH.
1. REMOVE LUGGAGE DOOR HINGE TORSION BAR LH
(a) Remove the floor carpet.
(b) Remove the floor finish plate.
(1) Remove the 2 screws and 2 No. 2 trim hooks.
(2) Remove the 2 bolts and rope hook assy
(3) Using a clip remover, remove the 2 clips and floor
finish plate.
(c) Remove the clips and trim cover inner LH and RH.
(d) Remove the torsion bar RH from the clip placed in the cen-
ter of the upper back panel.
(e) Remove the tip of the torsion bar from the roof side inner
panel by hand.
(f) Take out the hinge arm from the torsion bar in the rear
direction.
(g) Pull the torsion bar to your side in order to remove the U±
shaped part from the hinge support.

(b) Remove 5 camshaft bearings.
(c) Remove the camshaft.
(d) Tie the timing chain as shown in the illustration.
NOTICE:

16. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise, and make sure the cam-
shaft timing gear does not rotate.
(b) Cover all the oil ports with vinyl tape except an advance
side port shown in the illustration.
(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm
2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the ports with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.
