TITLE:
Use Special Adapter to Test Fuel Fill Caps Properly

APPLIES TO:
All Models

SERVICE TIP:
If a customer comes into your shop hot under the collar that his or her vehicle flunked a state I/M (Inspection/Maintenance) program test (smog check), and all because of a fuel fill cap, don't rush off and replace the cap. The problem might not be the cap, but actually the equipment used for testing it.

If the smog check station is using a Waekon fuel cap adapter kit, they might not have the right adapter for testing the three-click-type fuel fill caps found on newer Honda models. These caps need a special adapter to test properly; otherwise, they'll flunk the test. This adapter (T/N FPT25-4) has a black cap and a dimple in the bottom. If your dealership is a state-certified smog check station, and you're not using this adapter, make sure you order one from Waekon at www.waekon.com. (On the home page, click on Quick-n-EZ parts. Enter FTP25-4 in the quick search: box, and click on GO.) This new adapter supersedes the original part.



A quick way to tell if the fuel fill cap is faulty is to check if the MIL is on. If it's not, the cap is OK and there's no need to replace it. You can also use the HDS to check that the OBD readiness codes are set and that there's no temporary DTC set for the EVAP system. If all is in order, the fuel fill cap is OK.

If the vehicle flunked the test at another smog check station, contact that station, as a customer courtesy, and tell them about this adapter. Although all smog check stations were sent letters from both Waekon and State Emission officials announcing the need for this new adapter, you
might also want to print your customer a copy of this S/N article for extra ammunition.
