GO TO 2.
PRECONDITIONING-2
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 and warm it up to normal operating temperature.

Select "FUEL PRES SEN V" in "DATA MONITOR" mode of "ENGINE" using CONSULT and check the indication under the following condition.

Monitor item	Condition		Indication
FUEL PRES SEN V	Engine: After warming up Selector lever: P or N position A/C switch: OFF No load	Engine speed: Idle	0.820 - 1.140 V
		Revving engine from idle to 4, 000 rpm quickly	0.820 - 2.900 V

Without CONSULT

Turn ignition switch OFF.
Start the engine and warm it up to normal operating temperature.

Check FRP sensor signal voltage.

ECM			Condition	Voltage
Connector	+	-
	Terminal
F91	44	45	[Engine is running] Engine warm-up condition Engine speed: Idle	0.82 - 1.14 V
			[Engine is running] Engine warm-up condition Revving engine from idle to 4, 000 rpm quickly	0.82 - 2.9 V

Is the inspection result normal?

YES

INSPECTION END.

NO

Proceed to DTC Diagnosis Procedure .

PERFORM DTC CONFIRMATION PROCEDURE-1
With CONSULT
1. Turn ignition switch ON (engine stopped).
2. Select "COOLANT TEMP/S" and "INT/A TEMP SE" in "DATA MONITOR" mode of "ENGINE" using CONSULT.
3. Check that the indicated value of "COOLANT TEMP/S" is less than 35 deg. C (95 deg. F).
4. Check that the difference between "INT/A TEMP SE" and "COOLANT TEMP/S" is 5 deg. C (41 deg. F) or less.
5. Check "Self-diagnostic result" of "ENGINE".
Is the DTC detected?

YES

Proceed to DTC Diagnosis Procedure .

NO

GO TO 5.

NO

GO TO 2.
PERFORM DTC CONFIRMATION PROCEDURE-2
1. Start the engine (or cranking) at least 1 second.
2. Check "Self-diagnostic result" of "ENGINE".
Is the DTC detected?

YES

Proceed to DTC Diagnosis Procedure .

NO

To check malfunction symptom before repair: Refer to Inspection .

NO

Confirmation after repair: INSPECTION END
