Hello,

New to DIY stuff. Got an Engine Check light. Looking for an OBD code reader/scanner. Any suggestion on model/brand? (Innova, Actron...etc?)

I have seen a lot of OBD II reader on eBay under $30.00, Are those usable? Please help newbie to choose.

Thanks!!!
99 MAXIMA GLE

 

Just as long it does what it's supposed to do...read diagnostic fault codes. I have an Actron and it works great. Luckily, since I owned it for a couple of years now, I haven't used it that much because I haven't gotten any SES incidents. (...knock on wood!) The more expensive scanners can read "P1" codes as well as "P0" codes. The less expensive models cannot read "P1" codes, therefore you have to make a trip to the dealer to extract those.

 

Or you could just go to Autozone to get it checked for free.

 

What's the difference between P0 and P1 codes? So which model should I choose?

And where is the connector that I can plug in the reader?

Thanks!!!

ETA: (Got answers)

1) P0 codes are "generic" codes. P1 codes are "manufacturers' codes".
2) The OBD II connector is right under the steering weel, at the bottom end of the plastic panel.

 

I have one of those ebay code readers. I don't know why but it never works on 96 GXE but it always works on 2000 I30. I guess you get what you paid for.
