Check Engine light really off?
January 24, 2011 8:04 AM Subscribe
The check engine light in my car is cycling on and off (on for a week, off for a week). Two questions:
1. If I take the car in for an emissions/smog test when the check engine light is off, will it pass.
2. If it fails, and it is early enough in the month, will I be able to drive the car until the end of the month when the sticker expires, or will it be "red-tagged" as soon as it fails?

Car is a 2001 Honda Accord with 163,000 miles on it, and I live in Pennsylvania. I would like to get another 6 months - 1 year out of the car, but the car also has a slightly wonky transmission, so I would rather not pay to replace the catalytic converter right now (since the transmission may go not long later).
When the light first came on (mid-December), there were three codes, one indicating that the cat was bad, one for the emissions canister and one for a bad transmission pressure switch. (I can get the exact codes if it would help for this question).
One more followon question - according to the Pennsylvania DEP site, if you spend $150 on things to resolve the check engine light, you can get a 1 year waiver on the emissions testing. In practice, is the waiver a difficult thing to get, or can you just spend $150 on something and automatically get the waiver?
