INSPECTION
1. INSPECT HEATER RESISTANCE OF HEATED
OXYGEN SENSORS (BANK 1, 2 SENSOR 1 AND
BANK 1 SENSOR 2)
(a) Disconnect the oxygen sensor connectors.
(b) Using an ohmmeter, measure the resistance between the
terminals +B and HT.
Resistance: 11 ± 16 W at 20°C (68°F)
If the resistance is not as specified, replace the sensor.
Torque: 45 N´m (450 kgf´cm, 33 ft´lbf)
(c) Reconnect the oxygen sensor connectors.
2. INSPECT HEATER RESISTANCE OF HEATED
OXYGEN SENSOR (BANK 2 SENSOR 2)
(a) Take out the front side of the floor carpet.
(b) Disconnect the oxygen sensor connector.
Using an ohmmeter, measure the resistance between the
terminals +B and HT.
Resistance: 11 ± 16 W at 20°C (68°F)
If the resistance is not as specified, replace the sensor.
Torque: 45 N´m (450 kgf´cm, 33 ft´lbf)
(c) Reconnect the oxygen sensor connector.
(d) Reinstall the floor carpet.

(f) Temporarily tighten the terminal nuts.
(g) Tighten the terminal nut
(1) Put a wooden block on the contact plate and press
it down with a hand press.
Dimensions of wooden block:
20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)
NOTICE:

Check the diameter of the hand press ram. Then
calculate the gauge pressure of the press when
981 N (100 kgf, 221 lbf) of force is applied.
Gauge pressure:

If the contact plate is not pressed down with the spe-
cified pressure, the contact plate may tilt due to coil
deformation or the tightening of the nut.
(2) Using SST, tighten the nuts to the specified torque.
SST 09810±38140
Torque: 17 N´m (173 kgf´cm, 13 ft´lbf)
NOTICE:
If the nut is over tightened, it may cause cracks on the in-
side of the insulator.

(h) Clean the contact surfaces of the remaining contact plate
and plunger with a dry shop rag.
(i) Reinstall the plunger, new gasket, end cover and lead
clamp with the 3 bolts.
