Evaporative Emission (EVAPI Control Diagram
The EVAP controls minimize the amount of fuel vapor escaping to the atmosphere. Vapor from the fuel tanK rstemporarily stored in the EVAP canister until it can be purged from the canister into the engine and burneo.
. The EVAP canister is purged by drawing fresh air through it and into a port on the intake manifold.The purging vacuum is controlled by the EVAP canister purge valve, which operates whenever engine cootanttemperature is above 149'F (65"C).
'WhenvaporpressureinthefueltankishigherthanthesetvalueoftheEVAPtwowayvalve,thevalveopensano
regulates the flow of fuel vapor to the EVAP canister.'Duringrefueling,thefueltankvaporcontrol valve opens with the pressure in the fuel tank, and feeds the fuel vaDorto the EVAP canister.

Fuel Supply System
Fuel Gauge Sending Unit Test
Special Tools Required
Fuel sender wrench 07XAA-001010A
NOTE; For the fuel gauge system circuit diagram, referto the Gauges Circuit Diagram (see page 22-58||.
1. Checkthe No. 10 fUETER {7.5A)fuse in the under-
dash fuse/relay box before testing.
2. Do the gauge drive circuit check (see page 22-56|l.
' lf the fuel gauge needle sweeps from minimuni
to maximum position and then returns to the
minimum position. the gauge is OK. Go to step 3.. lf the fuel gau ge need le does not sweep from
minimum to maximum position position and
then return to the minimum position, replace thegauge assembly and retest.
3. Turn the ignition switch OFF.
4. Remove the rear seat cushion {see page 20-80).
5. Remove the access panel (A)from the floor.
6. Disconnect the fuel pump 5P connector {B).

7. Measure voltage between fuel pump 5P connectorterminals No. 1 and No. 2 with the ignition switchON (ll). There should be battery voltage.
. lf the voltage is as specified, go to step 8.. lf the voltage is notasspecified,checkfor:
- an open in the YEUBLK or BLK wire.- poor ground (G551).

Turn the ignition switch OFF. Remove the No. 9BACK UP (7.5A)fuse from the under-hood fuse/
relay box for at least 10 seconds, lhen reinstall it.
Install a 2 Q resistor between fuel pump 5P
connector lerminals No. 1 and No. 2, then turn the
ignition switch ON (ll).

Low Fuel Indicator Test
Do the fuel gauge sending unit test (see page 11,
rcol.
. lf the system is OK, go to step 2.. lf the system has any malfunction, repair it.
Turn the ignition switch OFF. Remove the No. 9
BACK UP (10A) fuse from the under-hood fuse/
relay box for at least 30 seconds, then reinstall it.
Turn the ignition switch ON (ll) with the float at the
E (EMPry) position.
. lf the low fuel indicator is on, go to step 4.. lf the low fuel indicator is not on, refer to the low
fuel indicator Circuit Diagram (see page 22-58)
and check the circuit.
Turn the ignition switch OFF. Remove the No. 9
BACK UP (10A) fuse from the under-hood fuse/
relay box for at least 30 seconds, then reinstall it.
Lift the float above the LOW position.
. lf the lowfuel indicatorgoes off,the system is OK.. lf the low fuel indicator is still on, refer to the low
fuel indicator Circuit Diagram {see page 22-58),
and check the circuit.
