CHECK HIGH PRESSURE FUEL PUMP FUNCTION

With CONSULT

1. Start engine.

2. Select “FUEL PRES SEN V” in “DATA MONITOR” mode of “ENGINE” using CONSULT and check the indication as per the following conditions.

   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	1.17 – 1.84 V
   		Revving engine up to 4,000 rpm quickly.	1.17 – 3.44 V

Without CONSULT

1. Start engine.

2. Check the voltage between ECM terminals as per the following conditions.

   ECM			Condition	Voltage
   Connector	+	−
   	Terminal
   F72	7	2	[Engine is running] Warm-up condition Idle speed NOTE: The pulse cycle changes depending on rpm at idle.	3.1 V
   			[Engine is running] Warm-up condition Engine speed: 2,500 rpm	4.3 V

Is the inspection result normal?

Refer to Diagnosis Procedure.

Diagnosis Procedure

CHECK HIGH PRESSURE FUEL PUMP CIRCUIT

1. Disconnect high pressure fuel pump relay harness connector.

2. Check the continuity between ECM harness connector and high pressure fuel pump harness connector.

   ECM		High pressure fuel pump		Continuity
   Connector	Terminal	Connector	Terminal
   F72	7	F82	1	Existed
   	2		2

3. Also check harness for short to ground and short to power.
