I had a check engine light (code p420) and my mechanic said it will cost $1200 to change the catalytic converter but usually this is casued by a defective oxygen sensor.
I learned through some research that if I disconnect the battery and connect it back, the check engine light disappears (it did). When I took the car for emissions testing diagnosis I learned that my car was not ready to throw out a report as it was not driven long enough after the battery disconnection and it should be, before the "readiness code" is reset.
My question: How much should I drive before the emissions can read from my car computer? There is no check engine light right now but if I drive too long, it might come back, so what is the range of miles/speeds that I should drive?
Readers who have especially had experience with a Toyota Corolla can add more value to this question.
Thanks guys!
