I have had a 2002 Sonata GLS/LX with 70000 miles on it, for more than a
month now. And I'm in trouble already.When I am driving, the engine
will give a thud and then it will drop automatically to the 3rd gear.
After that, I can only access the 2nd and 3rd gear. I put an OBD
scanner and got 2 errors:
P1529 : Scair Solenoid circuit malfunction
P0715 : Input turbine speed sensor circuit malfunction.(the check
engine light is almost always on). The problem disappears when I
restart the car. I havent' been able to figure out what it means, or
what I should do. Can you tell me what the error could be, and the
lowest cost yet efficient way of getting it repaired? (This is in
Austin Texas)
