Welcome, lets start with some details on the vehicle and fill out your profile.

Always check the battery 1st.

 

how does the battery affect any of this? what should I be looking for when it comes to the battery?

 

Battery helps to provide electrical current for the vehicle. Best to load test it always first to eliminate that cause, check terminals and connections for corrosion.

This appears to be a pretty straightforward code, and not one that is going to be due to bad gas. (Or clogged injectors, which Sea Foam might help with.) You can look under the hood for cracked vac hoses coming off the manifold (e.g. the PCV), but if you don't see anything, it's time to go to a mechanic. (A vac gauge is a pretty standard mechanic's tool.)

 

Battery recommendation is a good one if you read through this forum although your codes may not be linked to a weak battery. Have seen many on the forum with 3 or 4 year old batteries and all sorts of strange warning lights etc. Replacing a 4 year old battery is cheap insurance and can save all sorts of frustration esp if your car is pre 2020. (again, many on this forum have much knowledge to share, let them help you by adding vehicle specs to your profile). 2020 onwards have larger batteries but if you drive infrequently or on mainly short drives these batteries will not last nearly as long as in a car from 10 years back..

 

I took the car to the dealer mechanic shop and the first thing they stated they had to put the machine on it to pull codes. I told them that it's been done 3x already but stil they insisted on doing it. Of course i said and contact me before you do any work. 1hr later they called and said
the source of my "emissions control problem" was rodent damage to evap purge hose causing vacuum leak. I don't believe I have a rodent infestation where I park the car but on the other hand, the pics are pretty convincing. So if I'm to accept the dealership at their word, Emission control problem was caused by rodents chewing the rubber hoses around the engine block...or just that one hose. Now to be fair to the dealership they only charge me $21.05 for the rubber hose and just a measly $339.99 to install said hose (heavy sarcasm here). I'm sure it took them less than 2 minutes to change out hose since it's readily accessible but I've learned my lesson on this matter. I'd like to thank each and everyone one of you for your suggestion.

Lastly I'd like to give a special shoutout to the member"TRAYLAW". In a private conversation, he told me to check two hoses and in my haste, I didn't even bothering to thoroughly check all the rest of the hoses in the area and the had hose was right next to the ones he told me to check. Oh well, valuable lesson learned. I'll forever be a hose checking fool. lol.

first two pics are the damage hose and the last pic is the new hose

control problem was caused by rodents chewing the lines.

I guess I see what looks like bite/chew marks all over the hose but where it is split, it looks flattened as though it got crushed.

 

Thanks for the updates, and filling out your profile.

 

Alright we got the code 2187 as well, so now I have to start looking too lean at idle too much air. where to start, not a battery issue sorry so it says

• Fuel pump
• fuel filter
• A.I answers
• O2 sensors

so where to start, love to hear some thoughts when the engine cools, the code is cleared can come on and reappear on the next start up we'll see.

 

339$ to install!. I suppose since there is 2 hose clamps they put 2 mechanics on it.

 

looking at this. photo is so far off of the actual car part, to me it more or less the air filter sensor
