I think I need to change my speedo cable....not working....96 nissan pick-up truck...2 wheel dr.

They don't use speedo cables anymore, all electrical. On or in the transmission there is a VSS- vehicle speed sensor, and it sends a signal by wire to the dash cluster, and also to the engine computer.
If you recall, the speedo cable would attach at the center rear of the speedometer gauge. I don't remember just when, but all car makers stopped using cables to indicate speed, I think it was in the '80's when they went to electrical devices rather than cables. You can use a voltmeter to run tests on the sensor and/or the wires, but I don't know the procedure. You would have to consult a repair manual for that. It is not uncommon for the sensor to fail, but could also be a wiring problem, or the speedo gauge itself, but that is less common.

Why is my 07 Mitsubishi triton speedo not working?

check the signal at the sensor with a multimeter. Most have three wires, one is a 12volt feed, one is a ground and the third is the signal wire. This wire is usually only 5volts and is grounded and ungrounded by the sensor in precise timing intervals as the sensor rotates. This means that to check its operation, make sure it has the 12volt feed and the ground, then, Jack up one rear wheel and chock the rest. Select neutral and release the parking brake.
Turn the ignition on BUT DONT START THE ENGINE. Reconnect ALL the wires to the sensor and then backprobe the signal wire you found earlier with a multimeter. Once you have the wire probed, slowly rotate the wheel by hand. The meter should show the 5 volt drop to nothing, then back to 5volts, then nothing, then 5volts and on and on as long as you rotate the wheel. If this 5volt is not present, check the instrument cluster as this 5volts comes from the speedo head. If the 12 volts is not present, check all fuses WITH A TEST PROBE - looking at the fuse is not enough and check the wiring to the sensor. If the ground is missing, check the earth point on the chassis under the rear of the cab and under the bonnet and repair and issues found.If all these tests show good and you have the alternating 5volt voltage, check the same signal wire at the cluster, if it still alternates when you turn the wheel by hand, repair the speedo head. If the 5volt signal feed from the speedo head is missing, check the wiring to the speedo head, if the signal is not present at the speedo head, repair the speedo head.

2003 VW jetta speedometer stopped working and the gas gauge started fluxuating as car turns etc. I replaced 2 speed sensors, one on top of trans with no pigtail just connector, Didnt solve problem. I...

The speed sensor that is under the trans. mount on the driver side sends the shift points to the computer telling it at what point to shift. The sensor that actually controls your speedometer is in the back near the firewall. It is tall and should have a silver heat shield over it. However, the problem that you have described sounds more like an electrical short or a wire grounding out somewhere. I would check for wires getting pinched under the steering column in the dash since things quit working when you are turning. Also check the wiring behind the instrument cluster. Elecrical problems can sometimes be complex and hard to find but with some due diligence they can be solved. Hope this helps.

Speed metter does not working also engiine light check on

This problem may be a fuse blown, or a faulty speed sensor, wiring for speedo, or other problems with speedo cluster. You said check engine light was on, this may be related to speedo. As computer reads vehicle speed it controls trans, engine, even radio volume as vehicle changes speed. Try looking for any blown fuses first.

Speedo dont work on audi 200 89

It's one of three things. The sensor in the transmission is bad. The wiring from the sensor to the speedometer is bad. Or the speedometer itself is bad.
