Code P1083-HCAC Valve Stuck Open (LS600HL)
Hello Lexus Community. I am the proud owner of a 2008 LS600hl with 141,000 miles. I love the car, but the check engine light is now on permanently and the estimated repair charge from my lexus dealership is outrageously expensive ($7563 plus Tax). Here is the official diagnosis and recommendation.
"Code P1083 - HCAC Valve Stuck Open in Bank 2 - Recommend Replacing Y- Pipe With HC Absorber - Possibly May Need Exhaust 2 Sensors with Exhaust Gaskets - $7563 + Tax."
I love the car, but can't afford this repair yet I can't stand seeing the Check Engine Light.
I would appreciate any advice.
Thanks!!!!

Ridiculous! I would have to continue driving it with the check engine light on or upgrader to a new model. I know I'm not willing to pay that much to have it repaired. You might try an independent shop.

I believe this was the same issue another hybrid member had recently that posted here. Needless to say, so glad I dumped my 600hL. May want to look at this post I found with a simple search on P1083.

Also, I believe the Carista App or Techstream can reset that light for you ;-)

Assuming this failure is the same as the others in that other thread, that part fails like clockwork at enormous expense.
Didn't someone else just buy a used hybrid and posted about it here. I wonder if his was pre or post failure and if it was pre, ouch to that poor soul.

Yeah...this is painful. I've had it reset 3-4 times. The first time it stayed off for a couple months, but now it seems permanent. No apparent impact on performance but I hate seeing the check engine light and for a fully dealer maintained vehicle it's unacceptable to live with a CEL.
I purchased the car for $53k in 2011 with 50k miles so at least I didn't get slammed with the full load and it still looks great.
Thanks Lexus community.....I have to figure this one out. I will keep you updated.

Cut a small piece of electrical tape and put it over the check engine light bulb on the instrument cluster so it isn't glowing in your face, then just get back to enjoying life. I've had customers who didn't have the money or want to do the repairs and I would tell them it's your car just cover the light then. Many did and drove another 100k no problem. Emission testing areas are another story if they require the light to function correctly. In Denver early on your light had to work right or you failed. Then after a few years it changed to the light could stay on and if you passed the tailpipe test you still passed emissions. Just a couple years ago they went back to the light must work correctly for you to pass.

Call Lexus corporate and see if they can offer help. If I'm not mistaken, others were able to negotiate a discount on repairs by them paying for parts and you the labor, especially since this seems to be a common problem. Be sure to mention that.

I have the same issue with the hydrocarbon... whatever happened to your WD40 effort? Were you able to get the valve unstuck from a always open position? Thanks in advance!

From your experience do you know if it would be possible to grease it without dropping the exhaust pipe ? Do you need to cut open a hole in the pipe ?
