3. Select “FUEL INJECTION” in “ACTIVE TEST” mode, and select
“HO2S2 (B1)” as the monitor item with CONSULT-II.
4. Check “HO2S2 (B1)” at idle speed when adjusting “FUEL INJECTION” to±25%.
“HO2S2 (B1)” should be above 0.68V at least once when the “FUEL INJECTION” is +25%.
“HO2S2 (B1)” should be below 0.50V at least once when the “FUEL INJECTION” is-25%.
CAUTION:
Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
Without CONSULT-II
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeter probes between ECM terminal 95 [HO2S2 (B1) signal] and engine ground.
4. Check the voltage when revving up to 4,000 rpm under no load
at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should be above 0.68V at least once during this
procedure.
If the voltage is above 0.68V at step 4, step 5 is not neces-
sary.
5. Keep vehicle idling for 10 minutes, then check voltage. Or check
the voltage when coasting from 80 km/h (50 MPH) in “D” posi-
tion with “OD” OFF (A/T), 3rd gear position (M/T).
The voltage should be below 0.50V at least once during this
procedure.
6. If NG, replace heated oxygen sensor 2.
CAUTION:
Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in)
onto a hard surface such as a concrete floor; use a new one.

INSPECTION AFTER REMOVAL
Camshaft Runout
lPut V block on, and support No.2 and No.5 journal of camshaft.
lSet dial gauge vertically to No.3 journal.
lTurn camshaft to one direction with hands, and measure cam-
shaft runout on dial gauge. (Total indicator reading)
Camshaft Cam Height
1. Measure camshaft cam height.
2. If wear is beyond the limit, replace camshaft.
Camshaft Journal Clearance
Outer Diameter of Camshaft Journal
lMeasure outer diameter of camshaft journal.
Inner Diameter of Camshaft Bracket
lTighten camshaft bracket bolt with specified torque.
lUsing inside micrometer, measure inner diameter of camshaft
bracket.
Calculation of Camshaft Journal Clearance
(Journal clearance) = (inner diameter of camshaft bracket) – (outer
diameter of camshaft journal).
lWhen out of the specified range above, replace either or both camshaft and cylinder head.Standard : Less than 0.04 mm (0.0016 in)
