BACKGROUND
For vehicles with SCI compressed natural gas (CNG)
fuel tanks, Honda is no longer replacing the fuel tank
and solenoid valve altogether. If you replace the fuel
tank solenoid valve, you must now reinstall the original
fuel tank.

Front Upper Tum Clip (2 required):
PIN 91561-SJD-003
Fuel Line Connector O-Ring (1/4 in. Port Side)
(2 required):
PIN 91066-SlG-A0l
Fuel Line Connector O-Ring (3/8 in. Port Side):
PIN 91066-SlG-B0l

All SCI aluminum fuel tanks are eligible for fuel tank
solenoid replacement, but you must first get Tech Line
authorization.

Fuel Line Connector O-Ring (1/4 in.)(5 required):
PIN 91067-SlG-A0l

This service bulletin does not apply to Lincoln
Composite fuel tanks, which must still be replaced as a
remanufactured assembly. (Refer to Service Bulletin
01-005, CNG Fuel TankAssemblyln-Warranty
Exchange Program.) Check the fuel tank label to
confirm that the tank is from SCI.

Fuel Tank Solenoid Valve:
PIN 16750-RNE-A0l

REPAIR POLICY

installation of a new CNG fuel tank solenoid valve
assembly.

Fuel Line Connector O-Ring (3/8 in.)(2 required):
PIN 91067-SlG-B0l

Fuel Tank Solenoid Valve O-Ring:
PIN 17574-PDN-A0l
NOTE: If you are ordering this part for replacement
by a service facility that is not your dealer, you will
need to report the name and address of the shop

A WARNING
Compressed natural gas is flanunable and highly
explosive. You could be killed or seriously injured if
leaking natural gas is ignited.
Stop the engine, and keep heat, sparks and flames
away.
When venting fuel, follow local regulations
concerning venting natural gas. Consult your local
fire and environmental authorities for specific regulations. This procedure should be done outside, in a
well ventilated area, or in a properly equipped NGV
shop.

DIAGNOSIS

• Rear Seat-back Removal and Installation

NOTE: You must be a Honda NGV-Certified
Technician to do the fuel tank solenoid valve inspection
or replacement work.

• Rear Floor Undercover Removal and Installation

1. Follow the normal troubleshooting procedures
found in the service manual or on ISIS. If your
troubleshooting leads you to suspect the solenoid
valve assembly is faulty, go to step 2

Relieve the Fuel Tank Pressure
Vent the fuel pressure from the fuel tank with the CNG
Vent Tool set. Refer to the Fuel Pressure Relieving
procedure in the service manual under the "Fuel and
Emissions" section.

2.

NOTE:

Call Tech Line to assist and confirm the diagnosis
that a fuel tank solenoid valve assembly
replacement is necessary. You will need a Tech
Line reference number to place the order for the
replacement fuel tank solenoid valve assembly and
the fuel tank O-ring.

• Using the tank venting tool to relieve tank pressure
makes the solenoid valve unusable and it must be
replaced with a new valve.
• Do not use the fuel stem to relieve pressure on the
fuel receptacle line. If the fuel stem is removed, it
must be replaced with a new one.

Remove the Fuel Tank Assembly from the Vehicle
1. Remove the fuel tank assembly from the vehicle as
described in the applicable service manual. Online,
enter keywords FUEL TANK, and select the
appropriate procedure.

Remove the Tank Solenoid Valve
1. Loosen the large seal boot clamp. Pull the clamp
and the vent boot aside far enough to be able to
disconnect the two-pin connector from the tank
solenoid valve pigtail harness.

2. Position the four rubber blocks from the CNG tank
valve replacement kit under the fuel tank frame and
side rail. The joint block should be suspended
above the ground.

3. Use the large plastic wire tie to support the fuel joint
block lines up to the frame. Make sure that the joint
block bracket is attached. Leave the wire tie in
place until the lines are reattached to the new
solenoid valve.
NOTE: Do not overtighten the wire tie. This will
cause pressure on the fuel lines and may cause
problems aligning them to the new fuel tank valve.

2. Fold back the seal boot to access the fuel lines.
NOTE: Use an elastic cord to hold the seal boot out
of the way.
3. Loosen and remove the three fuel line nuts from the
connector fittings. Remove the O-rings. Support the
line connector on the valve with a wrench while
loosening the line nut.
NOTE: Always use two wrenches when removing
or installing the fuel line nuts.

6. Note the position of the line connectors. Remove
the three fuel line connectors.
NOTE: There are two smaller fittings. The one with
the shorter threads goes into the middle position of
the solenoid valve for the pressure relief valve.
7. Position the 2.5-inch socket from the kit over the
valve, with the pigtail harness coiled on the end of
the solenoid valve in order to fit it inside the socket.

Gently pull the fuel lines back slightly so you can
remove the fuel line connectors.
NOTE: Be careful not to bend the fuel lines
because they will not realign properly if bent.

8.

Use the breaker bar supplied in the kit to loosen the
solenoid valve.

DANGER: If the valve does not turn easily, the
tank has pressure in it. Stop and do the tank
venting procedure again. Do not proceed until there
is no pressure in the tank and the valve turns easily.

11. Install the fuel tank stand support tool, and the
threaded tipping handle from the kit. With the help
of another technician, stand the tank on its end and
allow it to drain for 20 minutes. Place a clean and
empty drain pan underneath the tank to catch any
liquid as proof of contaminated CNG.

NOTE: If any liquid is found in the tank, replace
both filters. Any water in the fuel tank indicates fuel
contamination and warranty consideration would
not apply. Discuss your findings with your DPSM or
Tech Line.

Remove the solenoid valve by hand and remove
the 0-ring.

Evaluate the New Replacement Solenoid Valve
Condition before Installing
1. Visually inspect the fuel tank solenoid valve for
damage to the threaded area, the O-ring seat area,
the wiring, and the connector.
> Fuel Tank Solenoid Valve

4. Momentarily connect the test harness to an
automobile battery or booster pack, and electrically
activate the solenoid valve.
• If the solenoid valve works properly, and you can
see the solenoid plunger operate, go to step 5.
• If the solenoid valve does not work properly,
obtain a new solenoid valve, and retest.

Inspect wiring.

5.

After confirming proper operation, the valve is
ready for installation.

Inspect wiring.

2.

Connect the solenoid valve test harness from the
kit to the solenoid valve 2-pin connector.

3. Using a DVOM, test the resistance of the new
solenoid valve. It should be 18 to 21 ohms.
• If the solenoid valve is within specification, go to
step 4.
• If the solenoid valve is not within specification,
obtain a new solenoid valve, and retest.

Install the Solenoid Valve
1. Use contact brake cleaner to clean the solenoid
valve sealing surfaces on the valve and the tank.
NOTE: Make sure there are no rag or paper towel
fibers left on any sealing surfaces.

5.

Set the torque wrench from the kit to 339 N•m
(250 lb-ft), and torque the solenoid valve while an
assistant holds down the side of the tank frame.
NOTE: Be careful not to bend the fuel lines.
