Nissan Altima HL32 Hybrid. Manual - part 301

EC-188

< COMPONENT DIAGNOSIS >

[QR25DE]

P0132 A/F SENSOR 1

3. Check the voltage between A/F sensor 1 harness connector and

ground.

Is the inspection result normal?

YES

>> GO TO 4.

>> GO TO 3.

DETECT MALFUNCTIONING PART

Check the following.

• IPDM E/R harness connector F10

• 15A fuse (No. 37)

• Harness for open or short between A/F sensor 1 and fuse

>> Repair or replace harness or connectors.

CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between A/F sensor 1 harness connector and ECM harness connector.

4. Check the continuity between A/F sensor 1 harness connector or ECM harness connector and ground.

5. Also check harness for short to power.
Is the inspection result normal?

YES

>> GO TO 5.

>> Repair open circuit or short to ground or short to power in harness or connectors.

CHECK INTERMITTENT INCIDENT

Perform

GI-42, "Intermittent Incident"

Is the inspection result normal?

YES

>> GO TO 6.

>> Repair or replace.

REPLACE AIR FUEL RATIO (A/F) SENSOR 1

Replace air fuel ratio (A/F) sensor 1.

CAUTION:

• Discard any sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard

surface such as a concrete floor; use a new one.

• Before installing new sensor, clean exhaust system threads using oxygen sensor thread cleaner

[commercial service tool: (J-43897-18 or J-43897-12)] and approved anti-seize lubricant (commercial

service tool).

Description

INFOID:0000000004362842

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 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:0000000004471354

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

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 11V at idle.
Do you have CONSULT-III?

JMBIA0112GB

Possible Cause

P0133

Air fuel ratio (A/F) sensor 1
circuit slow response

• The response of the A/F signal computed by

ECM from A/F sensor 1 signal takes more than
the specified time.

• Harness or connectors

(The A/F sensor 1 circuit is open or
shorted.)

• A/F sensor 1
• A/F sensor 1 heater
• Fuel pressure
• Fuel injector
• Intake air leaks
• Exhaust gas leaks
• PCV
• Mass air flow sensor

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT-III

1. Turn ignition switch ON (READY).

2. Depress accelerator pedal and wait at least 6 minutes.

NOTE:

If keeping depressing the accelerator pedal for more than 6 minutes, fuel will be cut off after some time.

3. Select “A/F SEN1(B1) P0133” of “A/F SEN1” in “DTC WORK SUPPORT” mode with CONSULT-III.
