Fuel Delivery and Air Induction: Testing and Inspection

2TR-FE FUEL SYSTEM:

ON-VEHICLE INSPECTION

1. CHECK FUEL PUMP
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON (IG).

NOTE: Do not start the engine.

(c) Turn the tester ON.
(d) Enter the following menus:
Select: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump Speed.
(e) Check the fuel operation by operating it with the Techstream.
If the fuel pump does not operate, replace the fuel pump.
2. CHECK FUEL PRESSURE
(a) Discharge the fuel system pressure.
(b) Using a voltmeter, measure the battery voltage.
Standard:
9.0 to 14 V
(c) Disconnect the cable from the negative battery terminal.
(d) Remove the fuel pipe clamp.
(e) Disconnect the fuel hose.





(f) Install SST into the vehicle.
SST: 09268-31012
09268-41500
90467-13001
95336-08070
SST: 09268-45014
09268-41200
09268-41220
09268-41250
(g) Wipe off any gasoline.
(h) Connect the cable to the negative battery terminal.
Torque: 3.9 Nm (40 kgf-cm, 35 in-lbf)
(i) Warm up the engine.
(j) Turn the ignition switch OFF.
(k) Connect the Techstream to the DLC3.
(l) Turn the ignition switch ON (IG).
(m) Turn the tester ON.
(n) Enter the following menus:
Select: Powertrain / Engine and ECT / Active Test / Active the Fuel Pump Speed Control / ON.
(o) Measure the fuel pressure.
Standard:
281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi)

- If the pressure is too high, replace the fuel pressure regulator.

- If the pressure is too low, check the connection between the fuel hose and fuel pump.

(p) Disconnect the Techstream from the DLC3.
(q) Start the engine.
(r) Measure the fuel pressure while the engine idles.
Standard:
281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi)
(s) Stop the engine.
(t) Check that the fuel pressure does not change for 5 minutes.
Standard:
147 kPa (1.5 kgf/cm2, 21 psi)
If the pressure is not as specified, check the fuel pump, pressure regulator and/or injector.
(u) Discharge the fuel system pressure.
(v) Disconnect the cable from the negative battery terminal.
(w) Remove SST while being careful to prevent gasoline splashes.
(x) Connect the fuel hose.
(y) Install the fuel pipe clamp.
(z) Connect the cable to the negative battery terminal.
Torque: 3.9 Nm (40 kgf-cm, 35 in-lbf)
3. CHECK FOR FUEL LEAK
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON (IG).

NOTE: Do not start the engine.

(c) Turn the tester ON.
(d) Enter the following menus:
Select: Powertrain / Engine and ECT / Active Test / Active the Fuel Pump Speed Control / ON.
(e) Check that there are no leakage in the fuel system.
