Component Inspection (High Pressure Fuel Pump)

INFOID:0000000012197781

CHECK HIGH PRESSURE FUEL PUMP-1

1. Turn ignition switch OFF.

2. Disconnect high pressure fuel pump harness connector.

3. Check the resistance between high pressure fuel pump terminals.

Is the inspection result normal?

YES

>> GO TO 2.

>> Replace high pressure fuel pump. Refer to

EM-49, "Removal and Installation"

CHECK HIGH PRESSURE FUEL PUMP-2

WITH CONSULT

1. Reconnect high pressure fuel pump harness connector.

2. Start the engine.

3. Check “FUEL PRES SEN V” in “DATA MONITOR” mode of “ECM” using CONSULT.

WITHOUT CONSULT

1. Reconnect high pressure fuel pump harness connector.

2. Start the engine.

3. Check FRP sensor signal voltage.

DTC CONFIRMATION PROCEDURE

INSPECTION START

Is it necessary to erase permanent DTC?

YES

>> GO TO 3.

>> GO TO 2.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to

EC-228, "Component Function Check"

NOTE:

Use the component function check to check the overall function of the IAT sensor 2 circuit. During this check,

a 1st trip DTC might not be confirmed.
Is the inspection result normal?

YES

>> INSPECTION END

>> Proceed to

EC-228, "Diagnosis Procedure"

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure 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, do not add fuel.

• Before performing the following procedure, check that fuel level is between 1/4 and 4/4.

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 4.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and let it idle for 60 minutes.

2. Move the vehicle to a cool place.

NOTE:

Cool the vehicle in an environment of ambient air temperature between

−10°C (14°F) and 35°C (95°F).

3. Turn ignition switch OFF and soak the vehicle for 12 hours.

CAUTION:

Never turn ignition switch ON during soaking.

NOTE:

The vehicle must be cooled with the hood open.

4. Start engine and let it idle for 5 minutes or more.

CAUTION:

Never turn ignition switch OFF during idling.

DTC No.

IAT SENSOR 2 B1
[Intake air temperature (IAT)
sensor 2 circuit range/perfor-
mance]

The comparison result of signals transmitted
to ECM from each temperature sensor (IAT
sensor 1, IAT sensor 2, ECT sensor, FTT
sensor, and EOT sensor) shows that the volt-
age signal of the IAT sensor 2 is higher/lower
than that of other temperature sensors when
the engine is started with its cold state.

• Harness or connectors

(High or low resistance in the IAT sen-
sor 2 circuit)

• IAT sensor 2
