Guys, searched around but found no part numbers for the oxygen sensors.

So, someone knows how many oxygen sensors and which are the part numbers the 06 GS 300AWD has?

Can you buy Denso instead of the Toyota branded parts?

Many thanks

 

89465 8946530830 SENSOR, OXYGEN. SENSOR, OXYGEN; LH
GS300 (GRS195) $169.96 8946530830
89465 8946530720 SENSOR, OXYGEN. SENSOR, OXYGEN; LH
GS300 (GRS195) $177.16 8946530720

I am getting those 2 different part numbers for the left side and two more


89465 8946530820 SENSOR, OXYGEN. SENSOR, OXYGEN; RH; RH & LH
GS300 (GRS190)
GS300 (GRS195) $154.45 8946530820
89465 8946530710 SENSOR, OXYGEN. SENSOR, OXYGEN; RH; RH & LH
GS300 (GRS190)
GS300 (GRS195) $177.16 8946530710


So, 4 sensors total? Which one is bank 1 sensor 1 ?

 

All those sensors are post cat sensors. Meaning that they are after the cats and would be bank X sensor 2. If your looking fro the pre cat sensor you would need the one that starts with 89467-30020 or 30010.

 

Thanks a lot for the info, I will look into it

 

Update

The A/F sensors were needed per the codes.


This codes appeared on the scanner. P0172 and P0175.

OK, so, after searching for info, first I cleaned the MAF sensor with a MAF cleaner.
I also changed the spark plugs. Still have the codes and have very high HC levels (and high CO)

Then, bought new and replaced the old A/F sensors of both banks.
They work perfect and the HC levels at high rpms really improved but still have high HC levels at idle. And the codes also reappeared.

What else to do guys? Any ideas

 

I would check to see if you have carbon buildup. When you pulled the o2 sensors were they covered in black carbon?

 

There is a service bulletin for these codes.

Yes, they had some carbon, especially at the tip.

Thanks a lot for the info. I will check it out
