Corolla check engine light
 

2001 Corolla S, 50000 miles on it, bought new, never had anything done to it
except oil changes. Took the car from Milwaukee to Austin, TX back in
April. Left early in the morning and drove to south of Bloomington, IL
which is about 4 hours. Stopped for gas. When I got on the road again, I
noticed the check engine light was on. First thing I thought of was the gas
cap was loose. Stopped to check that and it was tight. Check engine light
was on all the way to Bentonville, AR where I stopped at my sister's house
for the first night. Next morning, took off and the light was still on.
Stayed on until I crossed into Texas about 6 hours later.

Re: Corolla check engine light
 

Is there a routine engine check-up for a Corolla after 50,000 miles? Maybe that is it? Don't really know.
