PRECONDITIONING-I
If DTC Confirmation Procedure is 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, check that battery voltage is 9 V or more with ignition switch ON.

GO TO 2.
PRECONDITIONING-II
NOTE:
- When it is certain that the previous driving is performed with the engine warmed up, the next steps can be performed.
- When it is difficult to satisfy the conditions, performing Component Function Check can identify the presence or absence of malfunction in the part/system that may result in a possible cause of this DTC. (Perform DTC Confirmation Procedure as much as possible.)
1. Start the engine and warm it up until engine coolant temperature reaches 70 deg.C (158 deg.F) or more.
2. Stop the engine and leave the vehicle in a cool place (soak the engine) until the engine coolant temperature reaches 35 deg.C (95 deg.F) or less.
CAUTION:
- The difference between air temperature and engine coolant temperature must be 5 deg.C (9 deg.F) or less.
- Never turn ignition switch ON during soak the engine.
Are the conditions satisfied?

YES

GO TO 4.

NO

GO TO 3.

COMPONENT FUNCTION CHECK

With CONSULT

Turn ignition switch OFF.
Start the engine.
On CONSULT screen, select "ENGINE">>"Data Monitor".

Check the value of "FUEL PRES SEN V" under the following conditions.

Monitor Item	Condition	Values/Status
FUEL PRES SEN V	Engine speed: Idle	820 - 1, 220 mV
FUEL PRES SEN V	Engine speed: Revving engine from idle to 4, 000 rpm quickly	820 - 3, 060 mV

Without CONSULT

Turn ignition switch OFF.
Start the engine.
Check fuel rail pressure sensor signal voltage.

ECM			Condition	Value
Connector	+	-
	Terminal
F91	25	13	Engine speed: Idle	0.82 - 1.2 V
			Engine speed: Revving engine from idle to 4, 000 rpm quickly	0.8 - 3.0 V

Is the inspection result normal?

YES

To check malfunction symptom before repair: Refer to Intermittent Incident .

YES

Confirmation after repair: INSPECTION END

Proceed to Diagnosis Procedure .

PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT
1. Turn ignition switch ON (engine stopped).
2. On CONSULT screen, select "ENGINE">>"Data Monitor">>"COOLAN TEMP/S" and "INT/A TEMP SE".
3. Check that the indicated value of "COOLAN TEMP/S" is less than 35 deg.C (95 deg.F).
4. Check that the difference between "INT/A TEMP SE" and "COOLAN TEMP/S" is 5 deg.C (41 deg.F) or less.
5. Check "Self-diagnostic result" of "ENGINE".
Is DTC P119A or P119B detected?

YES

Proceed to Diagnosis Procedure .

NO

Conditions satisfied: GO TO 5.

NO

Conditions not satisfied: GO TO 2.
PERFORM DTC CONFIRMATION PROCEDURE-II
1. Start the engine (or cranking) at least 1 second.
2. Check "Self-diagnostic result" of "ENGINE".
Is DTC P119A or P119B detected?

YES

Proceed to Diagnosis Procedure .

NO

To check malfunction symptom before repair: Refer to Intermittent Incident .

NO

Confirmation after repair: INSPECTION END
