Hello again!

According to the Lexus FAQs I could post a code and he will tell me what it is. All I saw was code 21. So any one knows? Thanks!!!

Ok, I googled and this code means oxygen sensor. It was a different code for the sub 02 sensor. So does this mean the 02 sensor after the manifold?

Sorry, actually it said main 02 sensor so I figure this is the one closest to the radiator ?

Thanks for your input Zock, unfortunately that page only shows the obd2 codes which are for model years 96 and up only. Its good to know though...

there is no 21 code for a 94 es300 as that year is OBD2 compliant and not 1.

Oh, my mistake. I assumed it wasnt obd2 compliant because it had no obd2 style connectors, it had different diagnostic connectors. I have a obd2 code reader and I do not see any connectors to plug it into the 94 es300. My 2000 ML430 Benz has this connector under the dashboard driver side. Is there a connector on the es300 that I do not see?

Read somewhere obd2 connector is under instrument panel so first thing in the morning I will look for it and hopefully plug in my obd2 reader. Thanks for all your help. :cheers:

Thanks a lot zock, this forum is the best its really good that us lexus owners are helping each other out. Also, this forum has more info on our cars than the benz forum I joined. SKperformance really posted a lot of info on that faq, also that parts list with the dealer prices already and parts number. That is so cool!!!
