My car has 175000 miles.
My car has a manual transmission.

I would try to clear the code first by disconnecting the battery. Make sure you have the radio reset code. Leave the battery disconnected for at least 10 minutes. Reconnect the battery and enter radio code. The Check Engine Light should be off. If it comes back on that may mean you have another problem or the computer is bad. Have a diagnosis of the Check Engine code and a pinpoint test done completely before any moving forward with any other part replacements.
