Heated Oxygen Sensor (HO2S-2) Heater On-
Vehicle Inspection
S5JB0A1306010
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance of sensor
heater between terminals “V
B
” and “GND” at sensor
connector.
If found faulty, replace oxygen sensor.
NOTE
Temperature of sensor affects resistance
value largely. Make sure that sensor heater is
at correct temperature.

Removal
WARNING
!
To avoid danger of being burned, do not
touch exhaust system when system is hot. A/
F sensor and/or oxygen sensor removal
should be performed when system is cool.
1) Disconnect negative cable at battery.
2) Disconnect connector of A/F sensor and/or heated
oxygen sensor.
3) Remove A/F sensor (1) and/or heated oxygen
sensor (2) from exhaust No.1 pipe.
Installation
Reverse removal procedure noting the following.
• Tighten A/F sensor (1) to specified torque.
Tightening torque
A/F sensor (a): 45 N·m (4.5 kgf-m, 32.5 lb-ft)
• Tighten heated oxygen sensor (2) to specified torque.
Tightening torque
Heated oxygen sensor (b): 45 N·m (4.5 kgf-m,
32.5 lb-ft)
Camshaft Position (CMP) Sensor Removal and
Installation
S5JB0A1306013
Removal
1) Disconnect negative cable at battery.
2) Disconnect connector from CMP sensor.
3) Remove camshaft position sensor from cylinder
head cover (for J20 engine) or cylinder head (for
M16 engine).
Installation
1) Install camshaft position sensor to cylinder head
cover (for J20 engine) or cylinder head (for M16
engine).
Tightening torque
CMP sensor bolt (a): 11 N·m (1.1 kgf-m, 8.0 lb-ft)
