Check Engine Light - Code is p0410.

What is your question?

Recently got the car from a family member who had not driven the car much. Had check engine light with many codes but car ran good. Started shutting down after warming up and would run and start after cooling down. Fuel gauge did not work so we changed the Fuel pump and Fuel filter...still car did not run after getting warmed up. Found out about the Crank position sensor and changed that and car runs fine. After about a week of driving Check Engine light comes on and code says p0410. Car runs fine but need to get check engine light resolved so we can get car tagged in Texas.
