dude like every mechanic says they will scan the problem your ECU picked up for free.
no point just asking for codes.

P1529 means the TCU wanted the CEL turned on.

P0715 is a turbine speed sensor circuit malfunction.

You probably need a new speed sensor.

wat do you mean by the tcu wanted the cel on? can you get more clearer for me? lol

[187sks]

It means the CEL came on because the Transmission Control Unit told the ECU to turn it on.

okay...now how can i fix that problem???

You probably need a new speed sensor.

[01sonata17]

okay is there anyway i can find out if its either the input or output

I'm not sure what you're talking about exactly.

Code p0715 is a input speed sensor code. I would replace the input speed sensor and clear the codes. The P1529 is just from the Trans controller asking the Engine computer to turn on the CEL. Input sensor is the one under the bracket that holds the shift cable on the top of the transmission
