2006 gs 300. Been driving car around and the 3 lights came on which are vsc, Trac and check engine light all at the same time. Replaced the 2 front O2 sensors but the light keeps coming on and off. When I drive the car the car hesitates to go over 25 mph. Can someone please please help me to find a solution. Thanks

 

Welcome to the Club. You might want to try the 3rd Gen section. Also, try those terms in the search, you'll get quicker answers.

 

What are the trouble codes? More info would yield better answers.

 

I don't have the trouble codes. Where would I be able to obtain these from?

 

Obd 2 scanner. Go to an autozone. Or if your state dosent allow it get one online

 

So the code is P0037.

 

Help please

 

See above

Ten useless letters

 

You replaced two good sensors.

That code is for bank 1 sensor 2...a heat control curcuit on the rear sensor on cylinders 1,2,3 or bank 1.

You may also have a short in that curcuit.

 

Is there another code? Bank 1 sensor 2 usually means the post cat sensor. Typically, pre cat adjusts the fuel trims and post cats check if the cats are working. Post cats don't typically influence the fuel trim so I don't see how it could have hesitation. Something else is going on here

 

Welcome to ClubLexus.

First and foremost, you are in the section of the forum. You have a 3rd generation GS which has a very different architecture. This is the 2nd generation GS forum. Between these two generation, the engine is completely different.

Also as others have suggested, we will probably be able to help you better (and I suspect more of us will be willing to help) if you could even just do a common google search (e.g. What is Pxxxx Diagnostic Trouble Code (DTC)?" So you could have some very basic fundamental background of the topic at hand; you would be surprised how much more effective communication can be by just remembering hearing some terminology though you may not remember the definition.

Again, we are here to help but would make helping you much more easier if you could post in the correct sub forum and be proactive and at least googling. As a moderator, I have to make sure the forums massive amount of information remains well organized for future reference, therefore, I am moving this thread to the 3GS sub forum. Good luck.

 

I changed all 4 sensors and the check engine light vsc and traction control light came on again. Do u know it could be???? Thank u for your help

 

I changed all 4 02 sensors reset the code... the next day the lights came on again vsc check engine light and traction control light.... anyone have had the same problem??? I don't know what could be causing the lights to come on??? Please I need help..... thank u all for your time and help...

 

Instead of just throwing parts at the lights you need to take the car and have the issue properly diagnosed. Could be a wiring issue or another faulty part...(catalytic converter)

200 GS300 is also known for having the carbon build up issue.

 

hmmm those lights usually come on for the gas cap as well but it wouldnt affect driving like your mentioning it
