I've had a problem with my speedometer not reading the MPH for a while but it's really gotten to me now. I've changed the speed sensor like 3 times, changed back to my original cluster, changed the plug on the speed sensor, checked the wiring under the intake manifold and still the damn thing doesn't read the MPH. Can it be the transmission itself? if it helps, I full throttled the car in first gear the other day and the needle moved up to about 80 MPH and came back down quickly. What can it be? thanks! BTW, it's a D16Y7.

 

cluster wiring

 

Do you have CEL code 17?

The VSS has three wires -- (1) power wire from fuse 15, (2) ground wire, and (3) signal wire that branches to the cluster and gauge assembly. Check at the VSS connector that the power wire has battery voltage, the ground wire has continuity to ground, and the signal wire has continuity but no shorts.

 

Yes, I have CEL Code 17.

 

Start by checking the three VSS wires with a multimeter (see my post above).

 

There is a tiny gear that is inside the transmission. If everything checks out wiring wise you may need to replace the VSS speed gear. It hardly ever goes bad but if it breaks replacing the VSS won't fix the issue.

First, check the wiring and then the actual VSS gear.

 

Will do on checking the wiring...If it were to be the VSS speed gear, How hard would it be to change? Or is it better to replace it?

 

Below is for 92-95 Civics. Not sure whether 96-00 Civics are the same.

 

i had this happen to me be for, get something to clean the conectors. mine were green all i did was pop them out then got some wire and ran it through them. it has work every sents

 

Here are the parts for VSS for 96-00 Civics.

 

Forgot to mention i have a '94 dx tranny with a 2000 dx automatic Vss. Worked fine for about a year so i know they're compatible.

 

these things are headaches
