1.
Disconnect the mass airflow sensor connectors.
2.
Measure resistance between terminals 1 and 4.
Standard value:
13 - 17 kΩ [at -20°C (-4°F)]
5.3 - 6.7 kΩ [at 0°C (32°F)]
2.3 - 3.0 kΩ [at 20°C (68°F)]
1.0 - 1.5 kΩ [at 40°C (104°F)]
0.56 - 0.76 kΩ [at 60°C (140°F)]

Be careful not to touch the connector (resin section) with
the tool when removing and installing.
1.
Drain engine coolant, then remove the engine coolant
temperature sensor.
ZK600437AA00
2.
With the temperature sensing portion of engine coolant
temperature sensor immersed in hot water, check the
resistance.
Standard value:
14 - 17 kΩ [at -20°C (-4°F)]
5.1 - 6.5 kΩ [at 0°C (32°F)]
2.1 - 2.7 kΩ [at 20°C (68°F)]
0.9 - 1.3 kΩ [at 40°C (104°F)
0.48 - 0.68 kΩ [at 60°C (140°F)]
0.26 - 0.36 kΩ [at 80°C (176°F)]

3.
If resistance deviates from the standard value greatly, replace
the sensor.
4.
Apply 3M™ AAD part number 8731 or equivalent to threaded
portion.
5.
Install the engine coolant temperature sensor and tighten it to
the specified torque.
Tightening torque: 30 ± 9 N·m (22 ± 7 ft-lb)

1.
Disconnect the heated oxygen sensor connector and connect
special tool MB991316 to the connector on the heated oxygen
sensor side.
2.
Make sure that there is continuity [4.5-8.0 ohms at 20°C (68°
F)] between terminal No. 1 (red clip) and terminal No. 3 (blue
clip) on the heated oxygen sensor connector.
3.
If there is no continuity, replace the heated oxygen sensor.
4.
Warm up the engine until engine coolant is 80°C (176°F) or
higher.
5.
Rev the engine for 5 minutes or more with the engine speed
of 4,500 r/min.
6.
Connect a digital voltage meter between terminal No. 2 (black
clip) and terminal No. 4 (white clip).
7.
While repeatedly revving the engine, measure the heated
oxygen sensor output voltage.

REMARKS
When
revving
engine
0.6 - 1.0 V
If you make the
air/fuel ratio rich
by revving the
engine
repeatedly,
a
normal
heated
oxygen
sensor
will
output
a
voltage of 0.6 -
1.0 V.
⦆
Be very careful when connecting the jumper wire;
incorrect connection can damage the oxygen sensor.
⦆
Be careful the heater is broken when voltage of beyond
8V is applied to the oxygen sensor heater.
NOTE:
If the sufficiently high temperature (of
approximate 400°C or more) is not reached although the
oxygen sensor is normal, the output voltage would be
possibly low although the rich air-fuel ratio. Therefore,
if the output voltage is low, use a jumper wire to connect
terminal No. 1 (red clip of special tool) and terminal No.
3 (blue clip of special tool) of the oxygen sensor with a
(+) terminal and (-) terminal of 8 V power supply
respectively, then check again.
8.
If the output voltage is not within the standard value, replace
the heated oxygen sensor.
NOTE:
For removal and installation of the heated oxygen
sensor, refer to GROUP 15, Exhaust Pipe and Main Muffler .
