I been getting CEL's apparently from 3 things: failing O2 sensor, bad gas or an outdated software on our vehicles.

Did some research online and acura DID acknowledge my P0174 CEL error and released a software update, and since I only purchased my vehicle about 2 months ago I really can't tell what software version I have?

If i buy the Honda tool myself can i install the update?

Do you not have warranty from where you bought it from?

Nope, nada

You stated you installed high flow precats fairly recently within the past week. I'm pretty sure it's related to your install.

Check the wires of the o2.

I had similar codes when I installed my Pre-cat deletes. The check engine light didn't come on until about 4 days after I installed it. I messed with the o2 sensor wires a bit and it eventually went away. Its been over 2 years now and still no check engine light.

Could possibly be the sensors, but they look like they sitting tight and i really don't feel like wasting a trip to the mechanic if its not, so i rather see if maybe its a software issue and just update it, IF its still persists then the only logical thing to do is get the sensors checked it, I rather tackle the easy tasks first

No problem. I assumed you installed the hfpc yourself that's why I suggested checking the o2 sensor wires. Checking the wires isn't something you need to take it to a mechanic to do, but I'm guessing you got one to do it for you

Well i just called my nearest Acura dealership and i told them about the code and mentioned i replaced my cats, he assured me everytime THEY replace the cats they also replace the O2 sensors, because the used sensors might have a "gap" left out from the previous cat?

Kinda sounds like "bs" but hey it might be true, i mean i have 4 sensors so why only 1 giving me trouble and not all 4 if its true lol? He assured me a new sensor would cost me more then $150 (more then i anticipated) guess i'll just go with an aftermarket one then

I'm not even surprised a dealership would do that. They're not exactly known for re-using your old parts if possible.

And yes the o2 sensor is worth around $150. Here's the parts

Is there an answer to the original question (title of the thread) about the software update?

I ask because I know my software hasn't been updated during the entire length of my ownership of my TL. And it's not something I would want to pay top dollar to do if there's an easier way.
