has anyone had problems w/ their speed sensor n reverse light??? i've changed out speed sensor...thought it was the wire harness changed that too, still not workin...also thermostat won't open w/ motor runnin but tested w/ boiling water it opens...any suggestions???

 

i have the same problem in my car '00 EM1 Civic Si my speed sensor doesnt work and my reverse light either

 

so you replaced your vss? correct?

and your reverse lights dont work'?

your really confusing. how is the thermostat ground?.

 

What model do you have? My '92-'95 model year has a reverse "sensor" I had to replace; it's on top of the tranny...I needed a Cresent wrench to get it off.
