Fuel System On-Vehicle Inspection

READ DATA LIST

1. Warm up the engine.
   

2. Turn the engine switch OFF.
   

3. Connect the intelligent tester to the DLC3.
   

4. Turn the engine switch ON (IG).
   

5. Turn the intelligent tester ON.
   

6. Enter the following menus: Powertrain / ENGINE / Data List.
   

7. Read the Data List.
   
   

   Intelligent Tester Display	Measurement Item/Range (Display)	Normal Conditions
   Fuel Press	Fuel pressure/ Min.: 0 MPa, Max.: 655.350 MPa	37 to 43 MPa: Idling
   Target Common Rail pressure	Target common rail pressure/ Min.: 0 kPa, Max.: 655.350 kPa	20 to 180 MPa

Remove the No. 1 engine cover.

Remove the bolt and the hose clamp.

Disconnect the fuel temperature sensor connector.

Resistance inspection

1. Using an ohmmeter, measure the resistance between the terminals.
   

   Standard resistance:

   Terminals	Condition	Resistance
   1 - 2	20°C (68°F)	2.32 to 2.59 Ω
   1 - 2	80°C (176°F)	0.310 to 0.326 Ω

   If the result is not as specified, replace the supply pump assembly.
   

Connect the fuel temperature sensor connector.

Install the hose clamp with the bolt.

Install the No. 1 engine cover.

PERFORM ACTIVE TEST

1. Connect the intelligent tester to the DLC3.
   

2. Turn the engine switch ON (IG).
   

3. Turn the intelligent tester ON.
   

4. Enter the following menus: Powertrain / ENGINE / Active Test.
   

5. Perform the Active Test.
