From other forums it really says "GAS CAP" I know thats what I said. Just take a look at the gas cap and make sure it fits and is sealed. Hope this helps. The good thing is its nothing serious.
That is actually gascap. Either the gas cap is loose or there is a large vapor leak in the fuel system.
It is a code for a faulty right rear wheel speed sensor.
The message is "gascap". Check to see if the gas cap is not tightened properly.
The computer has detected a malfunction with the electronic throttle system and set a trouble code.
A failure in the electronic throttle control system. You need to have the system checked for codes.
It depends on what you mean by measure, but if you mean in regard to the "50 caliber" part, caliber is the diameter of the piece of lead.
30 caliber with 30 grains of powder
9mm IS the caliber. If you mean what is it equivalent to, it is approximately the same as a .38.
If by 'set' you mean to match it to an old speedometer's settings to read proper speeds, look on the back of the speedometers and you should see a group of small switches. Make sure the switch positions on the new speedometer match the positions on the old speedometer. Assuming the old speedometer was set correctly to begin with, the new one should now read your speeds and mileages correctly. If it doesn't, contact your local Dodge dealer, they should be able to find the correct setting for your vehicle (they will likely need to know the VIN first).
Assuming you mean 2001 S-10, it doesn't have a speedometer cable, it is electronic.
On older vehicles, it would usually mean that the speedometer cable is broken or disconnected. On newer vehicles it would probably be a computer problem.
Is it a 12 valve engine or 24 valve? What do you mean by speedometer sensor? Do you mean Vehicle speed sensor? If so why do you want to change that?
