Component Inspection

1. Turn ignition switch OFF.
2. Disconnect high pressure fuel pump harness connector.
3. Check the resistance between high pressure fuel pump terminals as follows.
   RESISTANCE SPECIFICATION
   
   

   +	-	Condition		Resistance
   High pressure fuel pump
   Terminal
   1	2	Temperature °C (°F)	20 - 30 (68 - 86)	9 - 11 Ω

   Is the inspection result normal? 

   YES: GO TO 2.

   NO: Replace high pressure fuel pump. Refer to "REMOVAL AND INSTALLATION ".

WITH CONSULT-III

1. Reconnect high pressure fuel pump harness connector.
2. Start the engine.
3. Check "FUEL PRES SEN" in "DATA MONITOR" of "ECM" with CONSULT-III.
   VOLTAGE SPECIFICATION
   
   

   Data monitor item	Condition	Voltage (Approx.)
   FUEL PRES SEN V	Engine speed: idle	980 - 1, 200 mV
   	Engine speed: Revving engine from idle to 4, 000 RPM quickly	1, 100 - 2, 900 mV

WITHOUT CONSULT-III

1. Start the engine.
2. Check fuel rail pressure sensor signal voltage.
   VOLTAGE SPECIFICATION
   
   

   +		-	Condition	Value (Approx.)
   Fuel rail pressure sensor
   Connector	Terminal
   F26	2	Ground	Engine speed: idle	0.98 - 1.2 V
   			Engine speed: Revving engine from idle to 4, 000 RPM quickly	1.1 - 2.9 V

   YES: INSPECTION END

   NO: Replace high pressure fuel pump. Refer to "REMOVAL AND INSTALLATION ".
