Fuel Shut-off Valve

WARNING

!

 

Gasoline and gasoline vapor is toxic. A small 
amount of fuel remains in the fuel shut-off 
valve when checking it. Do not swallow the 
fuel when blowing the fuel shut-off valve.

 

1) When air is blown into the fuel shut-off valve with its 

side “A” positioned upward, the air can pass through 
to the canister side.

2) When air is blown into the fuel shut-off valve with its 

side “A” positioned sideways, the air cannot pass 
through to the canister side. If the fuel shut-off valve 
operates otherwise, it must be replaced.

Removal and Installation” (Page 1C-4).

2) Connect the ECT sensor (1) to the circuit tester and 

place it in the oil (2) contained in a pan, which is 
placed on a stove.

3) Heat the oil to raise its temperature slowly and read 

the column thermometer (3) and ohmmeter.
If the ECT sensor ohmic value does not change in 
the proportion indicated, replace it with a new one.

CAUTION

!

 

• Take special care when handling the ECT 

sensor. It may cause damage if it gets an 
excessive sharp impact.

• Do not contact the ECT sensor and column 

thermometer with a pan.
