3. Connect the voltmeter test leads to the following
HO2S terminals:
•
HO2S (front and rear)
— (+) lead—terminal A
— (–) lead—terminal B
4. With the vehicle stopped, run the engine at
3,000
rpm
until the voltmeter moves between
0.5 and
0.7 V
.
5. Verify that the measurement voltage changes
when the engine speed increases and decreases
suddenly several times.
•
If not as specified, replace the HO2S.
•
If the HO2S is okay, but O2S11 or O2S12 PID
value is out of specification, perform the
“Circuit Open/Short Inspection”.
Specification
Circuit Open/Short Inspection (Sensor)
1. Disconnect the PCM connector. (See
F–43 PCM
REMOVAL/INSTALLATION
.)
2. Inspect the following wiring harnesses for open or
short. (Continuity check)
Open circuit
•
If there is no continuity, the circuit is open. Repair
or replace the harness.
Front
— HO2S terminal A (harness-side) and PCM
terminal 1AB (harness-side)
— HO2S terminal B (harness-side) and PCM
terminal 2H (harness-side)
Rear
— HO2S terminal A (harness-side) and PCM
terminal 1Y (harness-side)
— HO2S terminal B (harness-side) and PCM terminal 2H (harness-side)
Short circuit
•
If there is continuity, the circuit is shorted. Repair or replace the harness.
Front and Rear
— HO2S terminal A (harness-side) and body GND
— HO2S terminal A (harness-side) and power supply
— HO2S terminal B (harness-side) and power supply
HO2S Heater Resistance Inspection
1. Disconnect the HO2S connector.
2. Measure the resistance between the HO2S
terminals C and D.
•
If not as specified, replace the HO2S.
•
If the HO2S heater is okay, but PID value is
out of specification, perform the “Circuit Open/
Short Inspection”.
Specification
Front : 3.0—3.6 ohms
Rear : 5—7 ohms
Engine speed
Voltage (V)
Acceleration
0.5—1.0
Deceleration
0—0.5
