It is a common fault with the EA, EB and ED falcons as well as some Holden Commodore and Nissan models which share the same speedo components. The problem usually occurs when they get to about 200,000kms. What the problem is there is a very small cog inside your speedo which drives the odometer mechanism. This cog loks like something you would find in a toy. What you will find has happened is one of the teeth has broken off it and it can no longer drive the odometer. Because it is a common problem the part to fix it is available just ring around or try ebay. To fix the problem yourself pull out the instrument cluster then undo the screws that hold the front panel (4 fairly short ones on the side and 4 very long ones on the back), remove front panel. Then undo the four centre screws which hold in the speedo. Once you pull it out remove the trip meter plunger and then the needle by turning it carefully in a counter clockwise direcvtion several times until it comes out. Then remove the screws that hold on the faceplate and remove same. The whole assembly will come away. Then undo the two screws that hold on the circuit board and when that comes away you will see the small cog. You will be suprised how small it is. If you have your part then replace it and screw it all back together. When you replace the needle turn it in a clockwise direction and be sure to set the needle on zero.
If the speedo il ok but the odometer doesn't work, take it to a speedo shop as the problem is in the speedo.
There is a separate motor that runs the odometer. It is not running for some reasson. TAke it to a speedo shop.
The little pot metal gear on the odometer shaft is slipping. The speedo needs to be opened up, and that gear either superglued to the shaft or replaced.
does the speedo work? the speedo, odo, and trip odo all work off the same cable if they are mechanical and not digital. so, if the speedo works, then the prob must be in the guage head. if it doesnt, then its 98 % cance theres a prob with the cable. 2% chance its with the drive gear in the trans.
I think it is a manual speedo so take the cable soose at the dash and pull the cable out. Then take it loose at the trans and pull the piece that is broken off out. Go to the parts store and get anew cable and install it with lots of speedo cable lube, If it is electric change the speed sensor. Last answer is incorrect. If the speedo didn't work then it would have been. The problem is with the cluster. Go to your local salvage yard or eBay and get another speedo. Getting closer. It is actually the small plastic gear in the odometer. You can get a new one at odometergears.com or get a whole new cluster.
Check: Cable to trany, gear in trany, speedo head in cluster
odometer won't work w/o speedometer working
The odometer runs on the same electronic gear driven sensor as the speedometer so if the speedometer is working and the odometer is not the problem is in the "Speed head" (speedometer unit in the dash). Mine and several others I have seen break at about 40,000 and will need replacing.
if it is all the gauges it's probably a fuse, or just some, like speedo and odometer it could be a bad wire
Hi, Assuming it is a EF / EF Falcon - May work for EA - BA Ford EF / EL Falcon - Turn of service reminder light Insert Keys Press odometer button and hold Turn key to ignition position (Lights on) Hold odometer button until you hear a beep · Service Light Is Reset
I have the same problem on an '89 Dodge Dynasty. I am told that the odometer and speedometer in my car are driven by separate cables and that I simply need a new cable for my odometer to function properly again. I have not verified this information, but it might get you on track.
I have a 1991 camara rs. The speedo stopped working. All other guages still work. The transmission has a gear operated sending unit that cost about $100.00. If that is good and your speedometer and odometer does not work your guage at the cluster is bad as is mine. One last check is does your cruise still work, mine does. Hope this helps, Big C
