DTC Logic
DTC DETECTION LOGIC
To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal fluctuates according to fuel feedback control.
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause | |
P0130 | A/F SENSOR1 (B1) (O2 sensor circuit bank 1 sensor 1) | A) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly in the range other than approx. 2.2 V. |
|
B) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly approx. 2.2 V. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A
With CONSULT
Is 1st trip DTC detected? YES >> Proceed to EC-211, "Diagnosis Procedure".
NO-1 ( With CONSULT)>>GO TO 3.
NO-2 ( Without CONSULT)>>GO TO 7.
3.CHECK AIR FUEL RATIO (A/F) SENSOR 1 FUNCTION
Does the indication fluctuates around 2.2 V? YES >> GO TO 4.
NO >> Proceed to EC-211, "Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-1
If “TESTING” is not displayed after 20 seconds, retry from step 2.
CAUTION:
Always drive vehicle at a safe speed.
Is “TESTING” displayed on CONSULT screen? YES >> GO TO 5.
NO >> 1. Check A/F sensor 1 function again.
2. GO TO 3.
5.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-2
Release accelerator pedal fully.
NOTE:
Never apply brake during releasing the accelerator pedal.
Which does “TESTING” change to? COMPLETED>>GO TO 6.
OUT OF CONDITION>>1.Retry DTC CONFIRMATION PROCEDURE.
2. GO TO 4.
6.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-3
Touch “SELF-DIAG RESULT” Which is displayed on CONSULT screen? YES >> INSPECTION END
NO >> Proceed to EC-211, "Diagnosis Procedure".
7.PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
Perform Component Function Check. Refer to EC-211, "Component Function Check".
NOTE:
Use component function check to check the overall function of the A/F sensor 1 circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-211, "Diagnosis Procedure".
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
With GST
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Never apply brake during releasing the accelerator pedal.
Is 1st trip DTC detected? YES >> Proceed to EC-211, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY
*1: Except California
*2: For California
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
*1: Except California
*2: For California
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
*1: Except California
*2: For California
*1: Except California
*2: For California
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to GI-39, "Intermittent Incident".
Is the inspection result normal? YES >> Replace air fuel ratio (A/F) sensor 1. Refer to EM-30, "Exploded View".
NO >> Repair or replace error-detected parts.
CD care and cleaning
Handle a CD by its edges. Do not bend the
disc. Never touch the surface of the disc.
Always place the discs in the storage case
when they are not being used.
To clean a disc, wipe the surface from the
center to the outer edge using a clean, soft
cloth. Do not wipe the disc using ...

Inspection and Repair
Inspection
When measuring voltage, wrap tin foil around the top of the negative
probe. Then press the foil against the wire with your finger.
Attach probe circuit tester (in Volt range) to middle portion of
each filament.
If a filament is burned out ...
Cruise control operations
The cruise control allows driving at a speed between
25 - 89 MPH (40 - 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control, push the
ON·OFF switch. The CRUISE indicator light in
the instrument panel comes on.
To set cruising speed, accelerate the ve ...
