2001 Lexus LS430, 178K miles just threw a PO325 code. No real symptoms...

Hi Scotty!

I enjoy watching your YouTubes, you're a real kick in the pants!

I love and so miss my late husband, who, in my opinion was the best mechanic, husband and dad ever.

AND, since he passed away 7 years ago, I have yet to find someone as knowledgeable and interesting enough to watch and listen to until I found your videos, ha!

So I have an '01 Lexus 430 that just recently threw a PO325 code.

I love my 24 year old son, and he has my car right now at his workplace repair shop, but he has had it for about a month, only making bits and pieces of time available for it when he can fit it in his busy schedule. (It's my 3rd vehicle so I'm not pressed to drive it), but I still would like to run a few things by you to see what your expert feedback is.

1-Have you seen a well taken care of '01 Lexus LS430 throwing a code for knock sensors at 178K miles before? 

2-Is this a common thing?  It hasn't shown any signs of the engine being sluggish at all, it's mostly a garaged vehicle and I use it for Sunday driving mostly, but I have been thinking about doing a 180K (90K) service on it soon, just because.

I understand my son would like to take care of the few things my car has going on, mainly that engine code, and he has said that in all his research and troubleshooting, so far everything is pointing to the B1S1 knock sensor, so he's supposed to get back to me and let me know what the cost of them are.

Also, since the labor requires going under the manifold, we agree that both knock sensors should be replaced.

Do you have any input that would be helpful, with your experience? I understand I should request OEM parts since Lexus vehicles are "picky" when it comes to electrical parts.

Thanks for any and all feedback in advance!

Anna 🙂 /p>
