HEATED OXYGEN SENSOR INSPECTION [FS]
Heated Oxygen Sensor Inspection
1. If the SST (104 Pin Breakout Box) are used,
check in the following order.
(1) Remove the PCM. (Refer to 01-40A
POWERTRAIN CONTROL MODULE (PCM)
REMOVAL/INSTALLATION [FS].)
(2) Connect the SST (104 Pin Breakout Box) to
the PCM as shown.
(3) Tighten the connector bolt.
Tightening torque
7.9— 10.7 N m
{80— 100 kgf cm, 69.5— 95.4 in lbf}
(4) Warm up the engine to normal operating
temperature.
(5) Measure the voltage at PCM terminal 35 and
60.

2. If the SSTs (NGS tester) are used, check in the
following order.
(1) Connect the SSTs (NGS tester) to the data
link connector.
(2) Select the “PID/DATA MONITOR AND
RECORD” function on the NGS tester display
and press TRIGGER.
(3) Select “02S11", and “0 2S 12” on the NGS
tester display and press START. The NGS
tester measures and shows the voltage.

(4) If not as specified, inspect the following.
• Intake-air system
• Fuel system
• On-board diagnostic system
(5) If these systems are okay, replace the heated
oxygen sensor. (Refer to 01-15 EXHAUST
SYSTEM REMOVAL/INSTALLATION [FS].)
(6) If not as specified, inspect the following.
• Intake-air system
• Fuel system
• On-board diagnostic system
• Related harnesses
(7) If these systems are okay, replace the heated
oxygen sensor. (Refer to 01-15 EXHAUST
