'95 ES300 O2 sensor codes
I have had problems with the O2 sensors throwing codes. Does anyone know which are commonly bad or what can be done on this. Thank you!

it's a 21 year old car, the o2's should be worn out by now. you'll just have replace them.
if you're short on cash you can disconnect them, (unplug) and run the car without them for a while, the ecu will use a default value to replace the values they should have been providing.
generic replacement o2 sensors are perfectly fine to use.

That may depend on the code reader I am using. The one the guys at AutoZone have cannot pinpoint which one. I have a friend/coworker who may have a better reader.

Do you have the codes? I hit a P0135 code not too long ago and it was the far back O2 sensor, the one that I had to reach under the car. The others should/could be accessible from the front and above.

I need to get the the codes ran again. It has been a while. I know the check engine light is on and I also have the O/D OFF light blinking at a one second interval. How many O2 sensors are there? At least two different ones available I see, but I have heard of vehicles having multiple.

My '00 has three, one on each manifold and one behind the cat, that I know of. I had to replace the two in the engine bay a few years back. Easy one is pictured above. One in the back took some reaching and my buddy and I stripped out the threads a little getting the old one out. Threads were galled. Used the "old" front one we took out to run new threads in and installed the new one. No problems since. Make sure you get the correct one/ones. The leads for the electrical connectors are different lengths. And, they are A/F sensors.... Think the end is heated so a little more to them than a straight O2 sensor.

Got the codes read and cleared. Going to try to get my inspection today since only one system of seven shows as "not ready".
catalyst not ready
P0170 fuel trim malfunction bank 1
P0115 engine coolant temperature circuit malfunction
P0773 shift solenoid E electrical
6 of 7 readiness monitors are complete

- catalyst not ready = replace o2 sensor either before or after catalyst
- P0170 fuel trim malfunction bank 1 = replace air fuel sensor bank 1
- P0115 engine coolant temperature circuit malfunction =replace engine coolant tempature sensor
- P0773 shift solenoid E electrical =replace shift solenoid E
- 6 of 7 readiness monitors are complete = no idea what this is about.

I still have not done this, but I got a warning today for overdue inspection. Looks like Denso are the least expensive at Napa. Wait, maybe Bosch "universal" are. Napa only lists two. One front of catalytic converter and one rear of.
