The check engine light came on so I took the car to the dealer.
The 99.95 diagnose came up with both oxygen sensors were bad.
800+dollars. You have got to be kidding! Right after Christmas and
the taxes are due on our home we don't have the money for this.
56,250 miles on a 2002 SC430 and both sensors go out at the same time?
To make it worse the check engine light was off when I picked it up
but now and the SVC lights are on and I'm when I'm amost home and
the check engine light comes on again. So now I have 3 lights on.

Can any body help?

 

just take out both oxygen sensors and put them in a ziplock bag with some vinegar i think. and it cleans them out? someone chime in here with what your supose to use

 

you can buy the non-OEM o2 sensors like BOSCH brand that will be a lot cheaper.

However, you need to find a shop other than Lexus to replace them for you.
You should be able to save around $300 to $400, I guess.

Or you can DIY to save even more.

 

One of my 02 sensors went last month, watch out as there are 4 of them

 

I just got in to my 2003 sc430 last fall....the vsc vsc off and the tranny light came on......AAAAAGGHHHH...anyone near Bethel Park Pa besides a dealership know a good mechanic???? This is my first problem

 

Toyota is always an option. They usually run 30-50% less than Lexus.

 

Does the emission warranty cover these?

 

Thanks, I called the lexus dealership...95 flat rate....but asked if my gas cap was tightened 3-4 clicks....So i am gonna try running for about 40-50 miles like he said that might reset it ..before I try the local auto parts store to see if it codes. If I do Have to go to a dealership, It Will be toyota! Used to work for a dealership...I just kills me to pay Those fee

 

Go get an OBDII reader, you can read codes and clear them out.
