Weird Speedo Related Problem - R34 Gtt

[R-SPEC]

so today my car's speedo started playing up

first, it wouldn't read past 110km/h instead it would just drop to 0km/h and stay there until i went below 110km/h then it would start to read again

few hours later, it stayed glued to 0km/h and my check engine light came on and stayed on. switched the car on/off and drove around and it was the same, speedo not working at all and engine light on

anyone have a clue on what could be the problem?

thanks

could be a plug has come loose, or a wire is damaged or the speedo sender in the gearbox is knackered.

i'd start by getting under the car and checking the plugs on the side of the gearbox.

i had a look under the car and checked the gearbox and diff. all plugs/wires look fine and connected

i also pulled out the cluster and checked the wiring behind it and all is fine there too.

whats the next step?

could it be the cluster itself thats faulty?

I am having the same problem after I have replaced all the tail light bulbs.

Please help.

At least yours is reading correctly when its working, mine reads slower than the speed im doing

Its not like ive changed the wheels n tyres from standard

No bro, mine doesn't even read at all. Except last night, it started of on 60 when the car was standing still, it went to 170 when I was going at 60 according to the Gps.

This morning it didn't work at all.
