Driving to my girlfriends, out of nowhere my check engine light, vsc light, and vsc off light come on and while stopped or very low speeds car is shaking, I just had the upper ball joints replaced yesterday and am worried if the shop did something to my car, I don't have an idea of what it could be, please help

Just got the codes
P0400
P0455
P0136
Would a bad 02sensor do this?

Here is a list of code definitions. The P0136 is an O2 sensor code. The other two are emission system codes.

I guess my question is, whether anything else going bad could cause it to pop that code, before I order the o2 sensor.

theres like 3 or 4 O2 sensors.

Before you freak out. Disconnect your battery and clean the terminal and battery post. When you reinstall them make sure they are nice and tight

By your oil filter close to the firewall there is a vacuum hose with a green cap, sometimes it becomes disconnected triggering the cel, I'm not sure of the exact codes but mine triggered a few of them. I also had a problem with the car stalling out after getting an engine mount replaced, turned out the intake hose became disconnected from the airbox. Start with the simple stuff first, then move to the more expensive fixes

Those are bad oil control valve symptoms to a T...

Wouldn't that be something that would gradually happen? It was driving amazing then just out of nowhere the light pops on and starts driving crappy, when I turn on the car now, it feels like normal for the first second until the lights pop up then it gets rough. Hoping it's not anything expensive as I just put 1100$ into those upper ball joints and I likely won't have the money to fix anything for a good week and a half :/

Also has anyone had an o2 sensor go bad, and were the symptoms similar?

I've had my passenger side O2 sensor gone bad and now my driver side O2 sensor is giving me CEL.
None of them has caused any of the symptoms you described except that I feel a bit of shaking when the engine is cold (e.g. leaving to work at mornings). It happens on idle and when driving.

It's not that big of a deal so I'm not bothered about it. I have the replacement sensor but haven't got the time or motivation to change it.

Edit: There's four O2 sensors (2 pre-cat & 2 post-cat) so be sure to change the right one.

Edit2: Sorry, almost forgot that I did have the VSC lights on when my first O2 sensor went bad.
I changed the sensor and reset the VSC lights from the OBD port.

Here's the instructions:

Same with me no problems at all but not for me in my 400 it literally all happened at once overnight, right when I was pulling into work, my local lexus dealership shipped it to me the same day and I took it to my mechanic, problems solved , never had another problem like that, that was a year ago, I had the SAME problems and that solved it, it was like $140 for the part and an hour labor which was $75, I just got my upper ball joints and control arms in the mail also, I had to go with Raybestos professional grade, they are so much money for oem but your be happy u got oem, wish I could have I spent over $7000 in replacing parts since 2011, previous owner trashed my car, it's almost done finally...

Was it expensive to install?

Lukas99GS

Tried cleaning the battery terminal, checked hoses, couldn't find anything, car wouldn't start after I reattached the battery until I primed the gas while starting it, could it be fuel pump or fuel injectors possibly?

No it was like $75 after I seen the location I felt dumb cause it looks super easy to do
