under the dash right under the steering wheel
It means that the computer has detected a fault code that needs attention. Unfortunately, it isn't possible to guess what the computer is trying to tell you until you connect a code reader.
the code reader connector should be on the passenger side of car just under the edge of the dashboard on the left hand side next to the center console.
The access port is underneath the steering wheel, at the very and of the plastic protection. PS: Camry does not have a code reader, a code reader has to be purchased or you can use AutoZone free service to pull error codes out of the car computer.
In the multy-pin port located under the steering wheel
It uses the federally mandated OBD-II interface. Any code reader capable of reading OBD-II codes will work.
The plug is under the steering wheel, deep down and little bit to the left.
Trouble code P0104 means: Mass air flow or volume air flow circuit intermittent
Plug in the cable to an appropriate port. Driver software may also need to be installed.
The 1999 Volkswagon Cabrio OBD 2 port is under dash at left side
It could be the code reader or it could be a connector somewhere between the computer and the plug. Try a different code reader for now, see what happens. 1995 was in between OBDI and OBD II. A hybrid. Most shops cannot connect either. Dealers have the equipment.
The only way of knowing that is to use a code reader and look up the code that you get.
I reset mine on 1999 Trooper frequently with a code reader for my laptop. The cost is $80 - 120, for reader with cables.
