HEATED OXYGEN SENSOR
HEATED OXYGEN SENSOR INSPECTION
1. INSPECT HEATER RESISTANCE OF HEATED
OXYGEN SENSOR
Using an ohmmeter, measure the resistance between
the terB and HT.
Resistance:
California 2WD only
4.5 – 6.0
Ω
at 23
C (73
F)
Others
5.1 – 6.3
Ω
at 20
C (68
F)
If the resistance is not as specified, replace the heated
oxygen sensor.
2. INSPECTION OF FEEDBACK VOLTAGE (VF1)
(a) Warm up the engine.
(b) Connect the voltmeter to the DLC1 terminals VF1 and
E1.
HINT: Use SST when connecting between terminals
TE1 and E1 of the DLC1.
SST 09843–18020
Warm up the heated oxygen sensor with the engine
at 2,500 rpm for approx. 90 seconds. And maintain
engine speed at 2,500 rpm.

Connect terminals TE1 and E1 of the DLC1.
And maintain engine speed at 2,500 rpm.
Check that the number of times the voltmeter
needle fluctuates in 10 seconds.
