vent it from splashing inside the engine compart-
ment.

(j) Measure the fuel pressure.
Fuel pressure:
301 ± 347 kPa (3.1 ± 3.5 kgf/cm
2, 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
(k) Disconnect the TOYOTA hand±held tester from the
DLC3.
(l) Start the engine.
(m) Measure the fuel pressure at idle.

6. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
4 and 5.
Resistance: 0.2 ± 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
7. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 4 of
the connector, and the negative (±) lead to terminal 5. Check
that the fuel pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.

Keep the fuel pump as far away from the battery as
possible.

Always do the switching at the battery side.

Diagnostic Process Flow Chart
(Continued on following page)
PRELIMINARY CHECK
Fuel level should be between
1/4 and 3/4
Visually inspect for presence
of Fuel/Gas Cap
DO NOT TIGHTEN OR REMOVE!
PRESSURIZE EVAP SYSTEM (System Integrity Check)
This test checks for leaks in the canister and fuel tank sides. The CCV and Air Inlet Lines will be checked
separately.
A) Clamp the air drain hose on the charcoal canister with the supplied hose pliers from the EVAP System
Pressure Test Kit.
B) Locate the vapor pressure sensor. If the vapor pressure sensor has two hoses connected to it,
disconnect the hose between the air drain hose fitting at the vapor pressure sensor and plug the hose.
C) Connect the pressure supply hose from the Pressure Test Kit to the Green EVAP System Service Port
located on the EVAP Purge VSV line in the engine compartment.
D) Using the directions on the inside of the EVAP System Pressure Test Kit lid, pressurize the EVAP
system. Once pressurized, turn off the pump and seal the system (Pressure Hold Switch to ªClosedº
and Vent Switch to ªClosed).
E) After 30 seconds, note the pump pressure gauge reading and the Scan Tool vapor pressure
sensor reading.
F) Compare the readings to one of the four conditions listed below and proceed as directed.
DO NOT PROCEED! NG
OK
SCAN TOOL SETUP
A) Connect Scan Tool to DLC3 on vehicle.
B) Go to the SETUP menu and select UNIT CONVERSION.
C) Under VAPOR PRESSURE, Select ABS for absolute pressure, and mmHg for millimeters of mercury.
This is to match the Repair Manual specifications.
D) Go back to FUNCTION SELECT menu and select ENHANCED OBD II.
E) Select NORMAL MODE. Then select CURRENT DATA and USER SELECT.
F) Using the arrow key, select VAPOR PRESS from the DATA LIST and select YES.
G) Press ENTER. You will now be able to monitor the Vapor Pressure Sensor reading.
START
If vehicle is ECHO, go directly to ªECHO Canister and Tank Leak Checkº on page 14.
If vehicle is not ECHO, follow the flow chart below.
