Fuel System On-Vehicle Inspection

Connect the intelligent tester to the DLC3.

Turn the ignition switch on (IG). Do not start the engine.

Select the following tester menus: POWERTRAIN / ENGINE / ACTIVE TEST / FUEL / PUMP / SPEED.
Operate the fuel pump.

Touch the fuel hose in the engine compartment to check the fuel flow, and you will also be able hear the sound of the fuel pump.

Stop the fuel pump.
If there is no fuel flow, the fuel pump may not operate. Check the fuel pump circuit (RAV4_ACA30 RM0000017RH02BX.html).

Check that the battery positive voltage is above 12 V.

Discharge the fuel system pressure (RAV4_ACA30 RM0000017R800PX_01_0012.html).

Disconnect the cable from the negative (-) battery terminal.

Disconnect the fuel main tube (RAV4_ACA30 RM0000017R800PX_01_0007.html).

Install SST (pressure gauge) as shown in the illustration.

SST

09268-31011(95336-08070,90467-13001,09268-41500)
09268-45014(09268-41200,09268-41220,09268-41250)

Wipe off any gasoline.

Reconnect the cable to the negative (-) battery terminal.

Start the engine.

Measure the fuel pressure at idle.

Fuel pressure:

304 to 343 kPa (3.1 to 3.5 kgf/cm², 44 to 50 psi)

After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent fuel from spilling.

Reconnect the fuel main tube (RAV4_ACA30 RM0000017R500MX_01_0008.html).

Check for fuel leaks (RAV4_ACA30 RM0000017R500MX_01_0012.html).
