On-Vehicle Inspection
- CHECK FUEL PRESSURE
- Prepare for the inspection.
- Prepare a new fuel tube.
HINT:
Part No. 23901-21081
- Using a cutter knife, cut off the protector of the fuel tube as illustrated. Tear off the protector by hand, then remove the fuel tube connector.NOTE: If the protector is cut too deeply using the cutter, the O-ring of the fuel tube connector will be damaged.
- Prepare a new fuel tube.
- Discharge fuel system pressure (see REMOVAL ).
- Using a voltmeter, measure the battery voltage.
Standard voltage: 9.0 to 14 V
- Disconnect the cable from the negative (-) battery terminal.CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
- Disconnect the fuel tube (see REMOVAL ).
- Install SST and the fuel tube connector to the vehicle.
SST 09268-41047 (95336-08070), 09268-45014 (09268-41200, 09268-41220, 09268-41250)
- Wipe off any spilled gasoline.
- Connect the cable to the negative battery terminal.
- Connect the intelligent tester (with CAN VIM) to the DLC3.
- Measure the fuel pressure.
Standard: 304 to 343 kPa (3.1 to 3.5 kgf/cm 2 , 44 to 50 psi)
- If the fuel pressure is greater than the standard value, replace the fuel tank.
- If the fuel pressure is less than the standard value, check the connection of the fuel hose and fuel tank.
- Disconnect the intelligent tester from the DLC3.
- Set the vehicle to inspection mode.
- Start the engine.
- Measure the fuel pressure at idle.
Standard: 304 to 343 kPa (3.1 to 3.5 kgf/cm 2 , 44 to 50 psi)
- Stop the engine.
- After stopping the engine, check that the fuel pressure does not change for 5 minutes.
Standard: 147 kPa (1.5 kgf/cm 2 , 21 psi) or more
If the fuel pressure is not as specified, check the fuel tank or fuel injectors (see INSPECTION ).
- After measuring the fuel pressure, disconnect the cable from the negative battery terminal. Remove SST and the fuel tube connector while taking care to prevent spilling gasoline.
- Connect the fuel tube (see INSTALLATION ).
- Prepare for the inspection.
- CHECK FUEL PUMP
- Connect the intelligent tester (with CAN VIM) to the DLC3.
- Turn the power switch ON (IG).NOTE: Do not start the engine.
- Turn the intelligent tester ON.
- Select the item: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / FUEL PUMP / SPD.
- Check the fuel pump operation while operating it with the intelligent tester.

If the fuel pump does not operate, replace the fuel tank.
- CHECK FOR FUEL LEAKS
- Check that there are no leaks in the fuel system while fuel pressure is applied.
