Why is my 97 Holden vectra speedo and tacho not working the tacho just dead but speedo vibrates very fast whilst ignition is on?

Replace the speedo head assembly. It is a sealed unit, with no servicable parts. If the speedometer is working, then the cable and the speedo drive gears are working. The failure must be inside of the speedo head assembly itself.

Check Ignition switch. Does your speedo or tach work? If not it's the ignition switch. The transmission needs 12volts to operate and if the ignition switch is not working right you will not have first gear or overdrive, the suburban will try to take off in second and seems like your tranny is slipping!

Yes and no, the actual odometer and speedo assembly will fit but the the whole VP cluster will not, although it will bolt in the wiring is different and you will fry the dash or under dash wiring.

Switch ignition OFF, Press and hold button at speedo. After approximately 3 seconds the letters "INSP 0" will appearin the display. Continue holding button at speedo,depress brake and switch on ignition ON. The letters "INSP---" will start flashing in the display to be replaced after approximately 10 seconds with the message "INSPxxxx Km". Release button at speedo and brake pedal and switch off ignition.

Turn ignition to 'accessories' (not 'ignition on'), then press the trip computer button for about a second, and release. The display should flash 'km/h / mph'. Press the 'M' of the hours and minutes clock adjustment, at the left of the display, to select the speedo reading you want.

The gauge has failed.

If the speedo stops also, it is the speed sensor. If just the odometer, take it to a speedo shop.

hya i had the same problem with mine one day it was working then while driving it just went off if the speedo is electrics ratha than speedo cable then it is the speedo sensor that bolts into the gearbox it should have a connector up from the sensor cable (blue cable) unclip it from there and unbolt i bought sensor from local scrapyard for £10 and replaced it took 5 min easy job hope…

93 tranny is electronic if your speedo isn't working it won't shift into 3 or OD. Your speed sensor is more than likely the problem.

Hold the speedo reset buton down when tirning on ignition after about 30 seconds it will reset.

Hey Tony==Either manual or electric spedo if this happens the problem in in the speedo and needs to go to the speedo shop. GoodluckJoe

All my dashboard lights won't work on my 2000 Holden Vectra. Cigarette lighter, stereo, speedo, heater control lights and gear selection lights are all in the dark. Any help would be greatly appreciated.

there is no speedo cable so if your speedo isn't working you either have a faulty sending unit or the dash half of it is bad

IT the back of the speed cluster the spring is war out GO to the junkyard easy fiX

Replace the Distributor, i did this on my 87, and my speedo started working again.

could be the speedo cable?

lift the bonnet ,top of gear box near the rear ul c a big 22mm nut ,open and pull,step 2 using 10 or 12 mm socket open nut Holden down speedo to gearebox.remove and replace.

The logical problem - would be a broken speedo cable. The speedo & odometer are both run from the same cable.

There is no speedo cable on a 96, GM quit using them in 1987. You have a speed sensor, which is located on the top rear of the transmission. It will have a couple wires coming off it in a plug, that run thru the computer, then to the speedo. If your speedo has quit working, has it also set a check engine light? If so, I would recomend replacing the speedo sensor.

Do you mean the speedo, or the fuel guage?

Your speedo cable is broke and needs to be replaced

Vehicle speed sensor approx £40 fitted.

could be crankshaft sencor or bad contact on connection behind spedo

buy a garmin gps for 69.00 tells you your speed or fix speedo

Switch ignition off, press & hold the button to the left of the speedo while switching ignition on. After 10 seconds the new interval will appear in the display accompanied by a beep. Release the button. Switch ignition off.

speedo connected to gearbox and connected to other end not brken but not working

if the speedo is also not working it could be a vss problem or an issue with the gear or square shaft where speedometer hooks to tranny/ if speedo works just no overdrive there is a temp sensor on the tranny that can keep od from working or may be wiring issue with factory od on/off switch

You may have a bad ground

HI Renew the speedo cable

Have you retrieved a code from the ECM? If so what is the code. Is the speedo working?

speedo has a wire from behind and it snaps loose sometimes. disassemble the dash and reattach it

Switch ignition OFF Press and hold in button between speedo & water temp Switch ignition ON (not start) Keep button in for 10 seconds Display will now read zero and "spanner" symbol gone Relaese button & switch ignition OFF

there is 2 of them depending on what type of tranny you have, the MAIN sensor that makes the speedo work is located on the rear transfer case and NOT on the tranny itself. the other is a much smaller sensor that does go on the tranny but that ones DOESN'T effect your speedo. if you speedo is not working then its going to be the BIG sensor in the rear.

Have you checked your fuses? My father had a 88 Chevy and the speedo fuse would fall out of the holder.

Yes, some vehicles that have output speed sensors use them for the speedometer signal.

Yes, or it's the plastic speedo gear that enters the transmission. An easy way to narrow it down between the speedo cable or the transmission gear is to disconnect the speedo cable from the transaxle (garden hose style), and attach the metal "key" end to your drill. Then spin the drill. If the speedometer reads like you were driving, then your cable is ok and it's your the gear in the transaxle. If the speedometer…

you need new clocks or (map sensor) or speed sensor together :-( had this prob my self

You can try to knock on the dashboard area around the speedometer. Or you could resolder the PCB on the backside of your speedo. A very common problem on 406's You can try to knock on the dashboard area around the speedometer. Or you could resolder the PCB on the backside of your speedo. A very common problem on 406's

its iether the fuse // or broken cable //or the gear link on the top back of the gearbox near the gear linkage

Switch the ignition on Immediately press the button located to the left of the speedo twice turn ignition off Press and hold the button whilst turning the ignition on after 10 seconds the new interval will appear accompanied by a beep release button turn ignition off I hope you found this helpful best wishes Mike

You may have to change the S.I. board batteries.

If only the odometer is not functional, then the cluster is bad. If both odo and speedo are inop then you have a possible speed sensor issue.

If it is not your speedo cable then it is probably a gear inside the speedometer. I fixed mine with superglue!

Is your speedometer not working? If your abs light or tracs light is on it may be the brake control module causing your speedo not to work.

I think that's supposed to be an S It would mean that the speed sensor isn't working or there is another problem with the speedo-ODO.

I'm afraid I don't know but I am struggling to find ANY Iveco wiring diagrams! I have a 1991 Daily 59-12 and the speedo has packed up. We have fitted a working recon one and its not working in MY Iveco. Have changed the sender unit in the gearbox too! We are getting positive readings for power into the speedo AND we have re fitted it to another Iveco where it works.....so need a wiring…

There is no speedo cable on a Neon. It uses a speed sensor located on the top of the right-hand axel output housing. It is a black unit that has a clip-in two-wire connector. If your speedo inside the car isn't working that's usually the culprit.

Its a little cog in the speedo. You need experts to fix, about $180.

If the speedo works and not the odometer, take it to the speedo shop as something is wrong in the speedo itself. You can't stop the odometer without stopping the speedo.
