Description

INFOID:0000000001670928

SYSTEM DESCRIPTION

The ECM performs ON/OFF duty control of the heated oxygen sensor 1 heater corresponding to the engine
speed and engine coolant temperature. The duty percent varies with engine coolant temperature when engine
is started.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, 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 between 11V at
idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON.

2.

Wait at least 5 seconds.

3.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-163, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000001670930

1.

CHECK GROUND CONNECTION

1.

Turn ignition switch OFF.

2.

Check ground connection E15. Refer to Ground Inspection in 

GI-58, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK HO2S1 POWER SUPPLY CIRCUIT

1.

Disconnect heated oxygen sensor 1 harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between HO2S1 sensor 1 harness connector and ground.

Heated oxygen sensor 1 
heater control circuit low

The current amperage in the heated oxygen sensor 
1 heater circuit is out of the normal range.
(An excessively low voltage signal is sent to ECM 
through the heated oxygen sensor 1 heater.)

• Harness or connectors

(The heated oxygen sensor 1 heater 
circuit is open or shorted.)

• Heated oxygen sensor 1 heater

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• 10A fuse (No. 54)
• Harness for open or short between heated oxygen sensor 1 and fuse

>> Repair or replace harness or connectors.

4.

CHECK HO2S1 OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between HO2S1 harness connector and ECM harness connector.

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 5.

NO

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

5.

CHECK HEATED OXYGEN SENSOR 1 HEATER

Refer to 

EC-164, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> GO TO 6.

6.

REPLACE HEATED OXYGEN SENSOR 1

Replace heated oxygen sensor 1.

CAUTION:

• Discard any heated oxygen 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 oxygen sensor , clean exhaust system threads using Oxygen Sensor Thread

Cleaner tool and approved anti-seize lubricant.

7.

CHECK INTERMITTENT INCIDENT

Perform 

GI-55, "Intermittent Incident"

.

>> Repair or replace.

Component Inspection

INFOID:0000000001670931

1.

CHECK HEATED OXYGEN SENSOR 1

1.

Turn ignition switch OFF.

2.

Disconnect HO2S1 harness connector.

3.

Check resistance between HO2S1 terminals as follows.
