I own a 2002 Honda Accord EX V6 car. It has 110K miles on it and i bought it from a dealer as-is last year.

Yesterday, the TCS and Check Engine light came up together. I stopped the car and restarted the ignition and the TCS light went off but the Check Engine light is still there.

I went to the autozone and the code they mentioned are P0740 and P1676. (apologies i mentioned incorrectly in the header)

What could be the issue and what should i start with?

What do you think it will cost for the repair?

Can I drive the car to work (50 miles a day) until I get time to get it repaired?

It happened y'day when i was returning from work. I stay in Chicago area and sometime last month TCS light stayed on when I switched the car on in early morning cold. But it went off when i restarted the car after some time. But this time, it came up with the check engine light which is still on...

Please suggest the next steps.
