Hello, I just recently got my TL Engine Check light came on. THen i noticed that my TCS light turns on and off at random times. So i took it to autozone and used the OBD II to get the engine codes. I only got one code: P0740. It reads that it's a TCC CIRCUIT MALFUNCTION. I'm guessing something to do with my TCS?

I dont know much about these codes so does anyone what I need to go to resolve this? Do i need to replace my TCS circuit? Please help me out.
