93 honda accord engine warning light

I have a Honda accord and the engine light went on. My mechaninc replaced
the temperature sensor and O2 sensor but the light still goes on after a
few miles. He wants to replace the computer now. Does this make sense?
Am I paying for unnessary sensors? Also the ABS system doesn't operate, is
it possible that is why the check engine light is on? I'm leaving tomorrow
for a vacation and I'd like it fixed before we go. Thank you!

 

When the engine light at the dash comes on, there are codes that may be read to
give more insight into the problem.

Go to www.autozone.com . Click on the "free repair guides" link on the right.
Put in your car's info. Keep clicking on links for the repair guides until you

then click on "Trouble Codes." This page will tell you how to read the codes and
provide other troubleshooting info specific to your 93 Accord.

Your mechanic should have done this. Did he tell you what codes were indicated?
