2007 Lexus LS460L VSC/PCS/check engine light on
Unfortunately, I paid cash for the car, so I won’t be turning it in! The car is actually a very nice car and rides very nice! It has its fair share of cosmetic issues, but most can be cleaned up with elbow grease, wet sanding, and a good compound! If I don’t get the dealership to respond to my needs and take care of the repair 100%, I’m going to the local TV stations for help! The pre owned manager told me that they only look at safety issues before selling a used car. So with thst response, they are going to take care of the yellow headlights since the light is being redirected due to the yellow tint!

the dealership contacted me today and quoted me 1700 to replace fuel pump gaskets, and O2 sensors, and then discounting it 15% for a total of 1500 and change! They then came back an hour later without a response from me, and said they would cover 500 of the bill, making my portion an even 1,000.00- needless to say, I will be meeting with the GM sometime next week, and after that, on to the Corporate office of a publicly traded company!

Same (PCS, VSC, engine) on a 130k 2010 LS460 AWD. Shop cleared the faults, but it came back after 3 weeks (on a hot day). Faults went away after 3 days with no action on my part (on a cold and rainy day). Took it to the shop and replaced the battery. Hope the gremlin is gone....

I have had the same problem. It was going away and coming back but now its been pretty constant. Will attempt a new battery soon. Changed out the gas cap and thought that helped but it came back a few days later.

Fixed!!!
I have a 2007 LS460L with 119k miles and it just recently gave me the check VSC and PCS warnings with the check engine light, warning triangle, VSC symbol, and PCS indicator on the dashboard.
I was going uphill at a decent pace on a hot day and the lights start coming up. I did not lose power or feel any adverse effects but I pulled over anyways and shut down the engine. I spent a few minutes on the forum to look up the posts on this issue and found it to be a common problem that mainly meant issues with the battery or an assortment of sensors.
I turned the car back on and the lights remained. I drove home 40-50 miles and did more research to find a solution.
Many posts suggested removing the negative line from the battery to allow for the computers to reset so I tried that and it worked. I did try the reset and engine start button after I pulled the battery so maybe that had something to do with it.
I've been driving for a couple of days now and the lights have not come back. I will be changing the 4 year old battery soon and hopefully that will avoid any recurrence.

UPDATE-
I went through all of the recommendations I could find to address the VSC PCS light issue.
- Changed the battery- Only fixed it temporarily with the reset
- Replaced old gas cap- Again temporary fix if any but still good replacement to have
-Cleaned the MAF Sensor- BINGO!!! A simple can of MAF Cleaner solved this issue completely.
I have now driven for over 5000 miles including a trip to Vegas in 120 degree heat and the Lexus is running strong!
The answer to this frustratingly nagging issue is cleaning the Mass Airflow Sensors!!!
It's an easy job and I did it myself in the driveway. Many instructional YouTube videos available. I just used the standard can of CRC brand MAF Cleaner even though the warning says not to use on Lexus.
Use caution with the tiny screws for the sensor itself. I lost one down the bay and I should have just stuffed my rag under the sensor to block any drops.
I hope this helps and saves you the time and trouble it took me to figure this out.

Whichever method used, avoid any direct contact with the MAF sensor wire, as this could cause issues and/or damage. The warning one might stumble across about not using CRC MAF Sensor Cleaner on Lexus vehicles, I believe refers to early Lexus models (early to mid 90s maybe?) that utilized a Karman vortex type air flow meter rather than a MAF sensor. In pic below, the air box cover and intake runner that houses the MAF sensor is what I remove by undoing the 2 latches and the worm gear clamp (circled in red).

2008 Lexus LS 460 check engine VSC and traction light all came on at once
These lights came on a couple days after I had been messing around with the fuses. I took it to the dealer, and they told me it was the ECU/PCM the computer needs to be replaced. They quoted me $1998.00 it has to be a simpler solution to this. Any suggestions?

My son took his car to the dealership and they told him he needed a pcm and a new alternator because his battery light on the dash kept coming on. We charged his battery and replaced his belt and it's fixed. They quoted him 1700 bucks. A 29 dollar belt and my time was cheaper. I hate Dealerships.
