Does anyone have an OBD II that would not mind clearing my computer out? I can come to you whenever is convenient just let me know.

I ran my car out of gas and after I started it the CE light came on and never went off.

^^i might be wrong, but i'm pretty sure they can only read codes. usually takes the nicer tools or manufacturer specific ones to clear hard codes.

^^^^have you tried pulling the negative cable on the battery for a few minutes? that'll clear most stuff unless it's detecting some other issue.

they can clear them, but they wont unless you ask them.

Yeah I let it sit over night with the batter unhooked. I will try advance today since its right across the street.

Anyone have an idea have an idea how many miles I need to get all the tests to register for an inspection? Last time I did this on hotcurlz24's car I had to drive it for a week straight to get all of the tests to pass.

When I worked for a shop, and we did work and then needed to inspect, it was 3 stop starts and 75 miles.

^yeah, ive heard anywhere from 50-100miles.

but ive also had a car passed (CEL was nothing major) after almost no miles.

ive heard it depends on what the CEL was.

I actually have a pretty good OBD II scanner at my place on Kaplan. It's the same brand as the ones they have at Advance but it can read for OBDII inspection readiness, pending codes, and various PID's on the OBD II protocol (fuel trim etc). It was only like $120 new on ebay, not that expensive.

i've tried that before with no luck. cel's will usually clear on their own with a certain number of key cycles depending on the vehicle (gm's are 40).

BBR, even the cheap 50 dollar scanners can read/erase.


Your car has to go through a drive cycle before it will pass all readiness tests. Every manufacturer is slightly different. Generally speaking anywhere from 50-100 miles, but it has to include x amount of time or miles below 20mph, certain amount of stop/starts, amount of time idling, etc. The evap systems also require a cold start in order to do the purge tests. This can take up to about 8 hours of cooling down, depending on ambient temperature.

If your car is older.. as in older than 2001 you can have a few tests not ready and still pass. I believe under 2000 is 3, 2001 is 2, 2002 and up is 1 or something similar to that.

I might be late but that's all I know on that subject

^^^ It depends on what year car you have as to the number of readiness monitors that are required for a valid emissions test. On my Actron scanner (basically the most expensive one you can get at autozone, except it costs half the price on ebay brand new) it will tell you the status of all you readiness monitors.

9/23/2008 7:10:47 PM

^ I believe I covered that in the latter part of my post

9/23/2008 7:23:38 PM

pre-2001 youre allowed 2 not ready monitors, after that its 1 not ready

and like everyone else said it just depends on you manufacturer as to what the drive cycle is for the car.
