reset cel

I had a cel a few days ago, so I purchased a scanner, a ACTRON CP9580. The problem turned out to be an O2 sensor. I have since fixed the problem. My question now is does anyone does anyone know how to reset the cel using the model listed above. I do have the owners manual that came with it but it doesn't explain how??
Thanks

If the cel comes back on each time you restart the vehicle, then you havn't fully diagnosed and fixed the underlying problem. Or the scanner itself is faulty, but unlikely imo.

Should be options to read codes, and clear codes in its menu. Must be koeo(key on engine off) to clear codes. It should clear them, and you should be able to go right back and check for codes, with none showing. Most OBDII codes will require the engine to actually run or attempt to run before codes will trigger.

I know that most jeep owners are not going to spend the money we do on scan tools, but keep in mind stuff put out by actron, and other budget priced tools aren't really great for diagnostic work. They leave a lot of information on the table vs the better stuff.

Yeah, the professional scanners are awesome. I have a toy-make believe $100-scanner and it is ok for some stuff but it does have a "code delete option." Not familiar with the one the OP has but there must be a "code delete" function. Mine has one.

But, if the code indicated a bad 02 sensor and it was replaced (hopefully with an OEM one) and that was the problem, then the code should clear itself after 3 run cycles I think anyway as long as the fault is not detected any more. (stone cold start and a good run so it might take a few days before it is gone).

Emissions codes typically take a lot more to clear, if they clear at all. Some require 100 cycles before it will turn it off.
