While drving on highway I get a check engine light code believe p0720 something about converter. Now I changed pretty much all sensor externally and also change fluid hoping for the problem to go away. No slips no problems with tranny it shifts perfect but it has that code and will not pass inspection in my state. Help from some one will be highly appreciated.. thanks

 

P0720 is generally referring to the VSS...so either a fault in the speed sensor itself, or in the wiring/circuit...check your wiring for cracks, bare wire, kinks indicating a broken wire in sheath...also you might try a continuity check on those wires...if your wires/harness check out fine, look into the sensor itself. BUUUT yeah...auto ek=eventual fail. bad auto trannys and all.

 

Do you know what kind of voltage should i be getting from each wire??
