A/F Sensor And HO2S Removal And Installation
Removal
WARNING: To avoid danger of being burned, do not touch exhaust system when system is hot. A/F sensor and HO2S removal should be performed when system is cool.
1. Disconnect negative (-) cable at battery.
2. Disconnect connector of A/F sensor and/or HO2S.
3. Remove exhaust manifold cover.
4. Remove A/F sensor (1) and/or HO2S (2).
Installation
Reverse removal procedure, noting the following points:
- Tighten A/F sensor (1) to specified torque.
Tightening torque
A/F sensor (a): 45 N.m (4.6 kg-m, 33.5 lbf-ft)
- Tighten HO2S (2) to specified torque.
Tightening torque
HO2S (b): 45 N.m (4.6 kg-m, 33.5 lbf-ft)
- After installation, check exhaust system for leakage from sensor with engine running.
