(c) Pressurize the EVAP system by 3.2 to 3.7 kPa (24 to 28
mmHg).
(d) Apply soapy water to the piping and the connecting parts
of the EVAP system.
(e) Look for areas where bubbles appear. This indicates a
leak point.
(f) Repair or replace the leak point.
NEXT
(a) Replace the charcoal canister assembly (See page EC-
8).
NOTICE:
When replacing the canister, check the canister
pump module interior and related pipes for water,
fuel and other liquids. If liquids are present, check
for disconnections and/or cracks in the following: 1)
the pipe from the air inlet port to the canister pump
module; 2) the canister filter; 3) the fuel tank vent
hose.

(b) Check operation of the fuel pump.
(1) Apply battery voltage to both terminals. Check that
the pump operates.
NOTICE:
• These tests must be done quickly (within 10
seconds) to prevent the coil from burning
out.
• Keep the fuel pump as far away from the
battery as possible.
• Always turn ON and OFF the voltage on the
battery side, not on the fuel pump side.
