P0133, P0153 A/F SENSOR 1

Description

INFOID:0000000004362091

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 measurement   = 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 via 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 approxi-

mately 800

°C (1,472°F).

DTC Logic

INFOID:0000000004362092

DTC DETECTION LOGIC

To judge the malfunction of A/F sensor 1, this diagnosis measures response time of the A/F signal computed

by ECM from the A/F sensor 1 signal. The time is compensated by engine operating (speed and load), fuel

feedback control constant, and the A/F sensor 1 temperature index. Judgment is based on whether the com-

pensated time (the A/F signal cycling time index) is inordinately long or not.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
Will CONSULT-III be used?

YES

4.

PERFORM DTC CONFIRMATION PROCEDURE-III

1. After perform the following procedure, “TESTING” will be displayed on the CONSULT-III screen.

-

Increase the engine speed up to between 4,000 and 5,000 rpm and maintain that speed for 10 seconds.

-

Fully release accelerator pedal and then let engine idle for approximately 10 seconds.

If “TESTING” is not displayed after 10 seconds, go to 

EC-1167, "Component Function Check"

.

2. Wait for approximately 20 seconds at idle under the condition that “TESTING” is displayed on the CON-

SULT-III screen.

3. Check that “TESTING” changes to “COMPLETED”.

If “TESTING” changed to “OUT OF CONDITION”, go to 

EC-1167, "Component Function Check"

. 

4. Check that “OK” is displayed after touching “SELF-DIAG RESULT”.
Is OK displayed?

YES

>> INSPECTION END

NO

>> Go to 

EC-1239, "Diagnosis Procedure"

.

5.

CHECK MIXTURE RATIO SELF-LEARNING VALUE

With GST

1. Start engine and warm it up to normal operating temperature.

2. Select Service $01 with GST.

3. Calculate the total value of “Short term fuel trim” and “Long term fuel trim” indications.
Is the total percentage within 

±15%?

YES

>> GO TO 7.

NO

>> GO TO 6.

6.

DETECT MALFUNCTIONING PART

Check the following.

• Intake air leakage

• Exhaust gas leakage

• Incorrect fuel pressure

• Lack of fuel

• Fuel injector

• Incorrect PCV hose connection

• PCV valve
