• Accumulation of debris to the signal plate of camshaft (1) rear end
• Chipping signal plate of camshaft rear end
Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Remove debris and clean the signal plate of camshaft

rear end or replace camshaft. Refer to 

EM-53,

"Exploded View"

.

6.

CHECK TIMING CHAIN INSTALLATION

Check service records for any recent repairs that may cause timing chain misaligned.

Are there any service records that may cause timing chain misaligned?

YES

>> Check timing chain installation. Refer to 

EM-43, "Exploded View"

.

NO

>> GO TO 7.

7.

CHECK LUBRICATION CIRCUIT

Perform “Inspection of Camshaft Sprocket (INT) Oil Groove”. Refer to 

LU-7, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Clean lubrication line.

8.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to 

GI-33, "Intermittent Incident"

.

>> Repair or replace malfunctioning part.

Component Inspection

INFOID:0000000005989235

1.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

1.

Turn ignition switch OFF.

2.

Disconnect intake valve timing control solenoid valve harness connector.

3.

Check resistance between intake valve timing control solenoid valve terminals as follows.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace intake valve timing control solenoid valve. Refer to 

EM-53, "Exploded View"

.

2.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

1.

Remove intake valve timing control solenoid valve.

2.

Apply 12 V between intake valve timing control solenoid valve
terminals 1 and 2, and then interrupt it. Make sure that the
plunger moves as shown in the figure.

CAUTION:

Do not apply 12 V continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.

Is the inspection result normal?

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10.5 V and 16 V at
idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and let it idle for at least 10 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-131, "Diagnosis Procedure"

.

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005989237

1.

CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT

1.

Disconnect air fuel ratio (A/F) sensor 1 harness connector.

2.

Turn ignition switch ON.

3.

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

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART

Check harness for open or short between A/F sensor 1 and fuse.

>> Repair or replace malfunctioning part.

3.

CHECK A/F SENSOR 1 HEATER OUTPUT SIGNAL CIRCUIT

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.

 DTC No.

Trouble diagnosis name

Possible cause

P0031

Air fuel ratio (A/F) sensor 
1 heater control circuit low

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

• Harness or connectors

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

• A/F sensor 1 heater

P0032

Air fuel ratio (A/F) sensor 
1 heater control circuit 
high

The current amperage in the A/F sensor 1 heater 
circuit is out of the normal range.
(An excessively high voltage signal is sent to ECM 
through the A/F sensor 1 heater.)

• Harness or connectors

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