Ok yl im stumped i replaced the vss and pigtail connector and still no speedometer. Any help would be appreciated.

I went through this recently with my 2g. Ended up being in the dash cluster itself. I did end up buying a new genuine Mitsubishi vehicle speed sensor before purchasing another dash cluster.

What happened to the cluster itself

Just the speedometer part failed in my original one.

check the gear and make sure the teeth are in good condition .

Just the speedometer part failed in my original one.

So only the speed part didn’t work or like your rpms and stuff cus I just swapped my vss and it still doesn’t move

Yep exactly only the speedometer part stopped everything else was fine. I did keep the new vss as well since my old one was rough and partly cracked.

Make sure you have the correct part, auto and manual versions are a different length.

Ok my spedo meter still isnt working just got a new sensor and pigtail for it. Does anyone have a diagram of what wires to splice together?

Yet another new sensor and pigtail or your still trying to make the ones you got last year work?

The sensor harness is simple IIRC, power ground, and signal. If it's like the 3kgt the signal is a voltage the cluster sources and the VSS pulses it to ground. (Edit - It looks like the ECU provides the +5 pullup for it)

There are several other things also connected to the VSS signal and any one of them can mess up the signal as well as a potential short or open on the wire. (Like the TCU, Cruise Control, and convertable top on a spyder)

Do you have a Multimeter?

A new sensor and pigtail i think my problem is how i have the pigtail wired i have searched far and wide for a diagram on how to wire it properly

Also the vehicle sat for a bit but was started and ran a few days a week. Was down with a work injury for the last 6 months

Our friend Hiroshi-san comes to the rescue and also gently points out that perhaps this is a 420A car. Checking your prior posts confirms. https://www.dsmtuners.com/threads/97-eclipse-gs-5-speed-replacing-the-vehicle-speed-sensor.531561/ I've editted the tag to clarify.

Did you get the new sensor to seat in the trans?

Based on the diagram above you should have ~8v on Pin 1, ~5v on Pin 3 and it should pulse 5v to 0v if you turn it by hand and ground on Pin 2

 

[Eclipseguy_36]

Yes it has properly seated im the trans. And from what im seeing i have the pigtail wired correctly but still no speedometer. Maybe a cluster issue?? Or a pcm issue?

@steve , thank you for editing!!

 

[Eclipseguy_36]

Also the check engine light has gone out since replacing the sensor and pig tail. So leaning towards a cluster issue?

 

[Sirius1995]

just buy a used cluster, should fix the problem

 

[Lou98GSX]

is this an auto or manual

 

[Eclipseguy_36]

Manual 5 speed

+1 on replacing the cluster.
