discali85, you need to start your own thread.

Now back to supra's problem. It does read

Primary HO2S (No. 1) Heater System-05.

The one problem I can see here is wiring. Another one may be an aftermarket sensor.

Did the sensor you installed have the same connectors or did you have to splice wires to install the sensor?

I am seeing same issue on my 99 Accord 2.3L ULEV (California), however I am confused about which o2 sensor to buy.
There is a Denso 234-4209 and there are several BOSCH models (upstream./downstream) .. it's confusing which one is the right fit.
Can you please help me find the replacement (DENSO or BOSCH) for this honda part (# 36531-PAA-305)?

I would go with Denso. As far as I know Denso is Honda's supplier for O2 sensors.

If you go to www.tegger.com you will find a page which lists Honda parts online. I believe majestichonda.com is one of them. You do not have to buy from them. Just see if the part you need is the right one.

Good luck,

Sam

Thanks for your reply.
I ordered a BOSCH #13075 over the weekend. Hope it is good too.
I will keep you posted on the outcome.
