Fuel Pressure: Testing and Inspection
CHECK FUEL PRESSURE
a. Check the battery positive voltage is above 12 V.
b. Disconnect the negative (-) terminal cable from the battery.
c. Remove the union bolt and 2 gaskets, and disconnect the fuel inlet hose from the fuel filter outlet.
CAUTION:
-
Put a shop towel under the fuel filter.
-
Slowly loosen the union bolt.
d. Install the fuel inlet hose and SST (pressure gauge) to the fuel filter outlet with the 3 gaskets and SST (union bolt).
SST 09268-45014 (09268-41190, 90405-06167)
Torque: 29 N.m (300 kgf.cm, 21 ft.lbf)
e. Wipe off any splattered gasoline.
f.
Reconnect the negative (-) terminal cable to the battery.
g. Connect a TOYOTA hand-held tester to the DLC3. (See step 1 in check fuel pump operation (a) to (e))
h. Measure the fuel pressure.
Fuel pressure: 301 -347 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, fuel hose connections, fuel pump, fuel filter and fuel pressure regulator.
i.
Disconnect the TOYOTA hand-held tester from the DLC3.
j.
Start the engine.
k. Measure the fuel pressure at idle.
Fuel pressure: 301-347 kPa (3.1-3.5 kgf/sq.cm, 44-50 psi)
i.
Stop the engine.
m. 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.
