So I have a p0720 (output speed sensor) and I cant figure out why. I replaced the trans about 6 months ago and it works great. No hard shifts, all gears are great, and no codes until now. I have to pass emissions so I cant have any codes present. I have another integra with no codes so I have swapped the speed sensor and the ecu and after about 3 miles the cel comes back on, same code. Any ideas? I dont want to be told I need a tranny cause this one works fine.

 

No ideas?

 

Bump for any tranny guys

 

does ur speedo work?
try a different cluster.

 

Yeah the speedo works fine. Why would the cluster throw an engine code?

 

Bump.

Did you ever figure out your P0720 code? I'm having the same issue and cant find any good solution threads.
