REMOVAL
1. 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.
2. REMOVE HEATED OXYGEN SENSOR
a. Disconnect the sensor connector.
b. Using SST, remove the sensor.
SST 09224-00010
INSTALLATION
1. INSTALL HEATED OXYGEN SENSOR
a. Using SST, install the sensor.
SST 09224-00010
Torque:
44 N.m (449 kgf.cm, 32 ft.lbf) for use with SST
40 N.m (408 kgf.cm, 30 ft.lbf) for use without SST
HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
b. Connect the sensor connector.
2. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
3. CHECK FOR EXHAUST GAS LEAKS
If gas is leaking, tighten the problem areas to stop the leak. Replace damaged parts as necessary.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
