Anyone have a picture of what sensor that is in my 02 rx300? This is crazy i just fixed my p0136 cel and now this one. Thanks

 

Ah yes, Bank 1, Sensor 2.

That's underneath the vehicle just behind the main catalytic converter.

 

i thought that was p0136??

 

They both refer to that sensor.

P0136
HO2S Circuit Malfunction, Bank 1 Sensor 2

P0141
HO2S Heater Circuit Malfunction, Bank 1 Sensor 2

 

so the new sensor i put in is bad??? already gezus

 

Well .... when ever you get a CEL it means a value being read is off and the sending sensor is noted.

The debug is where you have to isolate the reason. The sensor could be bad, the wiring-connector can be bad or the the sensor is reading and relaying the value what it reads and you have to fix the problem up-stream.

You're going to have to check the sensor resistance. It's probably easier if you can get someone who has a more advanced OBD2 reader that can read the oxygen sensor values and see what they are.

 

well i been looking to get a code reader any suggestions on which one to get?

 

If you have a laptop, I'd recommend the Elmscan5 compact, http://www.scantool.net/scan-tools/e...5-compact.html

I just posted in a related thread just now some pictures of what the digimoto software I got could do, but see this thread for the basic program that comes with the elmscan5 compact, https://www.clublexus.com/forums/rx-...-for-obd2.html

It does show a value on both of my scans the values for Bank 1, Sensor 2.

I'm not sure offhand what the cheapest handheld scanner is out there that could read the values you are looking for. On Amazon there are several Autel scanners listed that appear to show livestream data for under $100. I just picked up this reader (but it doesn't read sensor data), http://www.amazon.com/Autel-MaxiScan...4601836&sr=8-1
