P2A00 A/F SENSOR 1
Description INFOID:0000000004780338
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sen-
sor. The sensor element of the A/F sensor 1 is composed an elec-
trode layer, which transports ions. It has a heater in the element.
The sensor is capable of precise m easurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range.
The exhaust gas components diffuse through the diffusion layer at
the sensor cell. An electrode layer is applied voltage, and this current
relative oxygen density in lean. Also this current relative hydrocar-
bon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this
electrode layer of current. In addition, a heater is integrated in the
sensor to ensure the required operating temperature of about 800 °C
(1,472 °F).
DTC Logic INFOID:0000000004780339
DTC DETECTION LOGIC To judge the malfunction, the A/F signal computed by ECM from the A/F sensor 1 signal is monitored not to be
shifted to LEAN side or RICH side.
DTC CONFIRMATION PROCEDURE 1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
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
1. Clear the mixture ratio self-learning value. Refer to EC-33, " MIXTURE RATIO SELF-LEARNING VALUE
CLEAR : Special Repair Requirement " .
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for 1 minute under no load.
4. Let engine idle for 1 minute.
5. Keep engine speed between 2,500 and 3,000 rpm for 20 minutes. JMBIA0112GB

Diagnosis Procedure
INFOID:00000000047803401.
CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connections E15, E24. Refer to EC-125, " Ground Inspection " .
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace ground connection. 2.
CHECK HARNESS CONNECTOR
1. Disconnect A/F sensor 1 harness connector.
2. Check harness connector for water.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace harness connector. 3.
RETIGHTEN A/F SENSOR 1
1. Loosen and retighten the A/F sensor 1. Refer to EM-31, " Exploded View " .
>> GO TO 4. 4.
CHECK FOR INTAKE AIR LEAK
1. Reconnect A/F sensor 1 harness connector.
2. Start engine and run it at idle.
