Install SST (pressure gauge) as shown in the illustration
by using SST and fuel tube connector.
SST 09268 -- 41046, 09268 -- 41091, 09268 -- 45012
Wipe off any splattered gasoline.
Reconnect the negative (--) terminal cable to the battery.
1RZ--E:
Using SST, connect terminals +B and FP of the check
connector.
SST 09843 -- 18020
2RZ--FE:, 3RZ--FE:
Connect the hand--held tester to the DLC3.

Start the engine.
Measure the fuel pressure at idle.
Fuel pressure:
206 - - 255 kPa (2.1 - - 2.6 kgf/cm
Stop the engine.
Check that the fuel pressure remains as specified 5 min-
utes after the engine has stopped.
Fuel pressure:
2
147 kPa (1.5 kgf/cm , 21psi) or more
After checking fuel pressure, disconnect the negative (--)
terminal cable from the battery and carefully remove the
SST and fuel tube connector to prevent gasoline from
splashing.
SST 09268 -- 41046, 09268 -- 41091, 09268 -- 45012
Reconnect the negative (--) terminal cable to the battery.
Check for fuel leaks.
