We have an EZ Pass for our Ford E450. It only gives us the green light about half the times we go through a toll booth. The rest of the time it flashes yellow and says "Call EZ Pass". When I call them they don't know what the problem is (the account is fine). One time they suggested the system might be having trouble reading the license plate. It's a new plate mounted in the spot for it on the drivers side of the bumper. There is no cover or anything over it. I notice most newer models (ours is a 2006) have the plate in the middle. Has anyone else had this problem?They have told us to just ignore the message from now on but the toll history shows we are only getting charged for half the tolls. Okay, so maybe that's a good thing but I don't want to be in the middle of a trip and get stopped somewhere for not having the pass working correctly.I can't believe they don't know what's wrong. You would think the system would tell them what the problem is it's having.

How old is your tag? The tag has a battery in it, and that battery does eventually die. That's my bet.I'm pretty sure the placement of your license plate has nothing to do with it.Just a few months ago, we got notice from EZ Pass NY that they were replacing our tags to the new smaller, cylindrical ones. We got the new tags and had to return the old ones. They were ~6-8 years old.

We have the new smaller one. It's a month old.Also, they work on an RFID system. There is no battery in them. It uses the power from the transmitted signal at the toll booth to "excite" a small circuit inside the pass to enable it to broadcast a unique ID back to the receiver. Similar to security fobs on clothing in department stores that trigger an alarm at the front doors if they aren't removed by a clerk.

Is it on the windshield? The cabover may be blocking the signal. I've got one of the license plate mounted tags on my Class C.In most toll booths, the receiving antenna is the pizza box looking thing hung from the underside of the overhead canopy.

It's mounted behind the rear view mirror on the windshield. Maybe I'll try mounting it toward the bottom away from any defrost vents. That might give it enough angle. I have to be able to change it with another one I have for pulling a trailer so anything permanently mounted won't work.

I say you need a license plate mounted one. The cabove is blocking the signal.
