"HO2S2 (B1)/(B2)" should be above 0.70V at least once when the "FUEL INJECTION" is +25%.

"HO2S2 (B1)/(B2)" should be below 018V at least once when the "FUEL INJECTION" is -25%.

CAUTION:

Discard any heated oxygen sensor which has been dropped from a height 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 oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.
