Camry CE Sedan 4-Door L4-2164cc 2.2L DOHC MFI (1997)
Fuel Pressure: Testing and Inspection
FUEL PRESSURE TESTING PROCEDURE
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 09268-45012
(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 the 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/cm square, 44 - 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check these parts:
-
Fuel hoses and connections
-
Fuel pump
-
Fuel filter
-
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/cm square, 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
