6. 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 0.18V 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.
Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor
Thread Cleaner tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.
Without CONSULT-II
1. Start engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Set voltmeter probes between ECM terminal 50 (HO2S2 signal) and ground.
6. 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 6, step 7 is not neces-
sary.
7. Keep vehicle idling for 10 minutes, then check voltage. Or check
the voltage when coasting from 80 km/h (50 MPH) in D position
with OD OFF (A/T, CVT), D position (CVT) or 3rd gear position
(M/T).
The voltage should be below 0.18V at least once during this
procedure.
8. 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.

13. Remove valve lifters.
NOTE:
Identify installed positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator (A) vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If it exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL OUTER DIAMETER
Measure the outer diameter of camshaft journal with a micrometer
(A).
CAMSHAFT BRACKET INNER DIAMETER
Tighten camshaft bracket bolts with specified torque. Refer to EM-51, "INSTALLATION" for the tightening
procedure.Standard : Less than 0.02 mm (0.0008 in).

REMOVAL
1. Remove camshafts. Refer to EM-47, "Components" .
2. Remove valve lifters. Refer to EM-47, "
CAMSHAFT" .
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve
from dropping into cylinder.
CAUTION:
When rotating crankshaft, be careful to avoid scarring front cover with timing chain.
4. Remove valve collet.
Compress valve spring using Tool, the attachment and the
adapter (A). Remove valve collet with a suitable magnet hand
(B).
CAUTION:
When working, be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat.
6. Remove valve oil seal using Tool (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height “H” shown using Tool (A).
3. Installation of the remaining components is in the reverse order of removal.Tool number : KV101092S0 (J-26336-B)
