My daughters 97 civic had the check engine light come on and she says at 3000 RPM it started acting weak.

I drove it and had no isses, other than the light being on, took it to Autozone and here are the codes, anyone see this before??

P0700 - The PCM has received a signal to turn on the "Malfunction indicator lamp" from the transmission contril system.
P0715 - The PCM has determined that a malfunctionexists in the input circuit for turbine speed sensor.
