Hi everyone!

I apologize if this is the wrong place to post this, but my red service light came on, and I was told it was the 02 sensor on the second bank. So that light goes off, and my yellow check engine light comes on. Now my ABS light is on. Can someone help me out with this?

I see my biggest mistake was paying it off.

We need more details please year, make, model? You could try and scan it at most parts stores and then just google the fault codes. Also what if any symptoms are you having please.

 

I apologize for the lack of information. It's a 2002 4WD Chevy Blazer. My left tire feels funny, but my fiance said he didn't feel anything. Other than that, I have no symptoms except all these lights coming on.

 

*Moving to 2nd Gen Tech* - As the description for the Sights & Sounds section states, the topics in that section should be centered around pictures, videos, & sound clips. Technical questions belong in the technical sections.

What was the specific OBD2 trouble code (Pxxxx) that came up? Can you find it in our OBD2 code index (link to which can be found in my signature below)?

For the ABS light, you will need to have your ABS system scanned by a capable scan tool. A generic scan tool will not be able to access the EBCM (electronic brake control module) as it takes an enhanced scan tool to access the serial bus networked devices like the EBCM. Once you get that scanned, let us know the code and we'll go from there. Guessing at this point will just waste your time & money.

 

Abs light could just be a bad sensor. I would go and scan it for free at your local auto parts store. And make sure you write down the codes it gives you and post them up here. Its way easier to give ideas when we have that info. Also clear the codes and pay attention when you drive and see if anything triggers then to come back on.

 

Auto Zone told me my one light was the 02 sensor on the second bank. He said it wouldn't shut me down, but I may notice heating trouble when the weather turns cold.

Will Auto Zone scan my ABS?

 

Kyle had a good point you will need a more advanced scan to for the abs. You can auto zone first and let us know the codes. You might get lucky and it be something simple!!

 

Okay, I'll get to Auto Zone and see if I can get the codes. I just ran to the bank and to the store, and it went off and never came back on. What does that mean?

 

That's a good thing generally!! My truck will do that occasionally. I have had it happen twice when its hot out and I forget to shut off the AC before I turn the truck on. I just drive for a bit and it goes off again. The codes should be stored tho I believe. You should try and see what you get still and let us know!!

 

I will if it comes back on. Thank you so much!!
