 1.CHECK HEATED OXYGEN SENSOR 2 HEATER
- Turn ignition switch OFF.
- Disconnect heated oxygen sensor 2 harness connector.
- Check resistance between HO2S2 terminals as follows.
Terminal
| Resistance
| 2 and 3
| 3.4 - 4.4 Ω [at 25°C (77°F)]
| 1 and 2, 3, 4
| ∞Ω (Continuity should not exist)
| 4 and 1, 2, 3
|
Is the inspection result normal?
YES >>INSPECTION END NO >>GO TO 2.
 2.REPLACE HEATED OXYGEN SENSOR 2
Replace malfunctioning heated oxygen sensor 2. ■ CAUTION ■ - Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (1.6 ft) onto a hard surface such as a concrete floor; use a new one.
- Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner [commercial service tool (J-43897-18 or J-43897-12)] and approved anti-seize lubricant (commercial service tool).
