e. Install SST (pressure gauge) as shown in the illustration by using SST and fuel tube connector.
SST 09268-41047 (90467-13001, 95336-08070), 09268-45012 (09268-41250)
f.
Wipe off any splattered gasoline.

h. Connect the hand-hand tester to the DLC3.
i.
Measure the fuel pressure regulator.
Fuel pressure: 304 - 343 kPa (3.1 - 3.5 kgf/sq.cm, 44 - 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses and connections, fuel pump, fuel filter and fuel pressure regulator.
j.
Disconnect the hand-held tester from the DLC3.
k. Start the engine.
l.
Measure the fuel pressure at idle.
Fuel pressure: 304 - 343 kPa (3.1 - 3.5 kgf/sq.cm, 44 - 50 psi)
m. Stop the engine.
n. Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.
Fuel pressure: 147 kPa (1.5 kgf/sq.cm, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.
o. 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.
p. Reconnect the fuel tube (fuel tube connector).
