Component Inspection

INFOID:0000000012197757

1.

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I

1. Turn ignition switch OFF.

2. Disconnect exhaust valve timing control solenoid valve harness connector.

3. Check resistance between exhaust valve timing control solenoid valve terminals as per the following.

Is the inspection result normal?

YES

>> GO TO 2.

NO

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

EM-76, "Exploded View"

.

2.

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II

1. Remove exhaust valve timing control solenoid valve. Refer to 

EM-76, "Exploded View"

.

2. Provide 12 V DC between exhaust valve timing control solenoid

valve terminals 1 and 2, and then interrupt it. Check that the

plunger moves as shown in the figure.

CAUTION:

Do not apply 12 V DC continuously for 5 seconds or more.

Doing so may result in damage to the coil in exhaust valve

timing control solenoid valve.

NOTE:

Always replace O-ring when exhaust valve timing control

solenoid valve is removed.

Is the inspection result normal?

YES

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting 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 between 11 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

>> Proceed to 

EC-203, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012197759

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 2.

NO

>> Repair or replace error-detected parts.

 DTC No.

Possible cause

P0030

A/F SEN 1 HTR (B1)
(Air fuel ratio (A/F) sensor 
1 heater control circuit)

Deterioration in A/F sensor 1 heater performance.
(Voltage signal transmitted from A/F sensor 1 heat-
er to ECM is higher/lower than voltage in the nor-
mal range.)

• Harness or connectors

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

• A/F sensor 1 heater

P0031

A/F SEN 1 HTR (B1)
(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.)

P0032

A/F SEN 1 HTR (B1)
(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

(A/F sensor 1 heater circuit is short-
ed.)

GI-45, "Intermittent Incident"

.

NO

>> GO TO 4.

4.

REPLACE AIR FUEL RATIO (A/F) SENSOR 1

.

CAUTION:

• Discard any A/F 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 A/F 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).
