Overall Function CheckNEEC0149Use this procedure to check the overall function of the heated oxy-
gen sensor 2 circuit. During this check, a 1st trip DTC might not be
confirmed.
CAUTION:
Always drive vehicle at a safe speed.
Without CONSULT-II
1) Start engine and drive vehicle at a speed of more than 70 km/h
(43 MPH) for 2 consecutive minutes.
2) Stop vehicle with engine running.
3) Set voltmeter probes between ECM terminals 56 (Heated oxy-
gen sensor 2 signal) and engine ground.
4) Check the voltage when revving engine up to 4,000 rpm under
no load at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should be below 0.54V at least once during
this procedure.
If the voltage can be confirmed in step 4, step 5 is not
necessary.
5) Keep vehicle at idling for 10 minutes, then check the voltage.
Or check the voltage when coasting from 80 km/h (50 MPH)
in 3rd gear position.
The voltage should be below 0.54V at least once during
this procedure.
6) If NG, go to ªDiagnostic Procedureº, EC-3328.

With CONSULT-II
1. Reconnect all harness connectors disconnected.
2. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
3. Stop vehicle with engine running.
4. Select ªFUEL INJECTIONº in ªACTIVE TESTº mode, and select ªHO2S2 (B1)º as the monitor item with CONSULT-II.
5. Check ªHO2S2 (B1)º at idle speed when adjusting ªFUEL INJECTIONº to±25%.
SEF662Y
ªHO2S2 (B1)º should be above 0.56V at least once when the ªFUEL INJECTIONº is +25%. ªHO2S2 (B1)º should
be below 0.54V at least once when the ªFUEL INJECTIONº is þ25%.
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.
