350Z V6-3.5L (VQ35) (2003)
3. Check the following with engine speed held at 2,000 rpm constant under no load.
-
The voltage fluctuates between 0 to 0.3V and 0.6 to 1.0V more than 5 times within 10 seconds.
-
The maximum voltage is over 0.6V at least one time.
-
The minimum voltage is below 0.3V at least one time.
-
The voltage never exceeds 1.0V.
1 time: 0 - 0.3V->0.6 - 1.0V->0 - 0.3V
2 times: 0 - 0.3V->0.6 - 1.0V->0 - 0.3V->0.6 - 1.0V
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.
