| Need a better OBD2 tool
I've not had much success using the $90 fault code reader that I bought from my favorite New England discount parts house. Although I did get a read-out for a weak oxygen sensor the first time I used it, since then it usually fails to work... giving only an "E" ,error, read-out. I've tried all the things that the manual that came with the tool suggests and still can't get it to work. A local independent shop has been able to get fault code read-outs when the check engine light has come on recently, so I know that a proper tool will work. However the tool they have been using is a sophisticated, expensive fault code reader typical of that used by a modern repair facility. I can't justify spending the several thousand dollars that they did.
I would, however, like to get code reader at a reasonable price so that I can see what's happening when the check engine light comes on. Does anyone in the community have any suggestions ? Napa sells an OBD2 tool for about $150. Anyone have any experience with this item? |
