CHECK HEATED OXYGEN SENSOR 2-III
Check the voltage between ECM harness connector and ground
under the following condition.
Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 6. 6.
REPLACE HEATED OXYGEN SENSOR 2
Replace heated oxygen sensor 2.
CAUTION:
• Discard any sensor which has been dropped from a he ight of more than 0.5 m (19.7 in) onto a hard
surface such as a concrete floor; use a new one.
• Before installing new sensor, clean exhaust system threads usi ng Oxygen Sensor Thread Cleaner
[commercial service tool (J-43897-18 or J43897-12)] and approved Anti-seize Lubricant (commercial
