Resetting "Check Engine" Light (for nuissance issues)

...this is follow-on to my recent post on dealing with a faulty charcoal canister, but searching the archive, it seems to come up for a number of different problems.

My question is: can you just buy any old OBD II code reader and reset the code and clear the memory?

I noticed that a code reader is only around $35 and for a problem like the charcoal canister issue, where there doesn't seem to be a substantive mechanical issue involved, if the clearing the code can turn off the "check engine" light long enough to pass inspection, then I'd have no moral qualms about doing it...

Not all code readers have the ability to clear codes, but if yours does, then you're good to go.

It may clear the code but it still WONT pass inspection of the e-test because the fault is still there .

All youve done is clear the code temporarily not correct the fault.

Well, the inspection process already takes good care of that.

If you clear the codes, the maintenance indicators will also be cleared. These indicators show if on-board diagnostic tests have been successfully run. And when the mandatory ones are not set as "passed" by the on-board computer, you can't pass the test.

So what codes did you pull?
