Components
![Toyota RAV4. Air fuel ratio sensor](images/books/256/22/1.htm30.jpg)
On-vehicle inspection
- Check air fuel ratio compensation system
![Toyota RAV4. Check air fuel ratio compensation system](images/books/256/22/1.htm31.jpg)
- Connect the intelligent tester to the dlc3.
- Turn the ignition switch on.
- Select the following menu items: data list / a/fs b1
s1 and o2s b1 s2.
- Warm up the a/f sensor with the engine speed at
2,500 rpm for approximately 2 minutes.
- Keep the engine speed at 2,500 rpm and confirm
that the display of "a/fs b1 s1" is as shown in the
illustration.
Hint:
- The illustration may slightly differ from the display
on the intelligent tester.
- Only the intelligent tester displays the waveform
of the a/f sensor.
- Confirm that the display of "o2s b1 s2" changes
between 0 to 1 v with the engine speed at 2,500
rpm.

Ok:
the voltage output oscillates more than 8
times in 10 seconds.
Notice:
- Perform the check immediately after warming
the engine up.
- If the voltage variation could not be verified,
warm up the a/f sensor again. If it could not
be verified even after warming up the sensor
again, check for dtcs (see page es-292).
Removal
- Disconnect cable from negative battery
terminal
Caution:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
- Remove air fuel ratio sensor (for bank 1 sensor 1)
- Disconnect the sensor connector.
- Using sst, remove the sensor from the exhaust
manifold.

Inspection
- Inspect air fuel ratio sensor (for bank 1 sensor 1)
![Toyota RAV4. Inspect air fuel ratio sensor (for bank 1 sensor 1)](images/books/256/22/1.htm34.jpg)
- Measure the resistance of the sensor.
Standard resistance ![](images/books/256/22/1.htm35.jpg)
If the resistance is not as specified, replace the
sensor.
Installation
![Toyota RAV4. Install air fuel ratio sensor (for bank 1 sensor 1)](images/books/256/22/1.htm36.jpg)
- Install air fuel ratio sensor (for bank 1 sensor 1)
- Using sst, install the sensor to the exhaust
manifold.
Sst 09224-00010
Torque: 40 n*m (408 kgf*cm, 30 ft.*Lbf) for use
with sst
44 N*m (449 kgf*cm, 32 ft.*Lbf) for use
without sst
Hint:
- Use a torque wrench with a fulcrum length of 30
cm (11.81 In.).
- Make sure sst and wrench are connected in a
straight line.
- Connect the sensor connector.
- Connect cable to negative battery
terminal
- Check for exhaust gas leaks
