1999 Honda Accord Coupe
Shows P0420 Due to Use of AC during idle

The check engine light came up due after AC was used for 45mins - 1hr in idle state.

I tried to reset it the other morning after engine had cooled. But it was of no help.

I have 92,700 miles on the car and it has completed 9 years.
