2. O2 Sensor Heater Resistance Inspection
Turn the ignition switch OFF.
Disconnect the O
2 sensor 4P (Black) connector
and measure the resistance at the O
2 sensor con-
nector terminals of the sensor side.
Is the resistance within 10 – 40
Ω
(20
°
C/68
°
F)?
YES – GO TO STEP 3.
NO – Faulty O
2 sensor
3. O2 Sensor Heater Power Input Line Inspection
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage between O
2 sensor 4P
(Black) connector of the wire harness side and
ground.
Is there battery voltage?
YES – GO TO STEP 4.
NO – Open circuit in the Black/white wire
4. O2 Sensor Heater Open Circuit Inspection
Turn the ignition switch OFF.
Disconnect the ECM 33P (Light gray) connector.
Check the continuity between the ECM 33P
(Light gray) connector and O
2 sensor 4P (Black)
connector of the wire harness side.
Is there continuity?
YES – GO TO STEP 5.
NO – Open circuit in Black/green wire
5. O2 Sensor Heater Short Circuit Inspection 2
Connect the ECM 33P (Light gray) connector.
Check for continuity between the O
2 sensor
heater 4P (Black) connector of the wire harness
side and ground.
Is there continuity?
YES – Short circuit in Black/green wire
NO – Replace the ECM with a known good
one, and recheck; refer to Key Registra-
tion Procedures (page 21-6)
