Hi guys, need a little help with a rx330. Car threw check engine and vsc light. Error code p0037 b1s2. I've replaced sensors on my is300 and rx300 but can't find anything on the rx330. Popping the hood I only see 1 sensor. Can some please let me know where b1s2 is located or a how to? TIA

thanks for the diagram. My apologies but I was mistaken and wrote the code as p0137 but it is p0037 b1s2. Still the same bank and sensor so this should help. I plan on using a universal O2 sensor because the location of the sensor connection looks to be inside the dash console and will be a pain to get to. If you have a universal (cut/splice) type O2 sensor to recommend I would appreciate it.

 

It is NOT inside the dash. You have to get under the car and follow the rear exhaust manifold down about 8 inches an you will see it.

 

As HtownBlue points out you are just looking to get to the rear manifold. Similar location as the front, just on the rear bank. As for the type to get, I would stick with a known brand such as the OEM or Denso. Nothing to splice if you get one that states it is a "direct fit."

 

Thanks guys you've all been super helpful. I see where the connector is located and it should be an issue. I ordered the denso universal as I do not kind splicing and all 6 sensors I've done in the past have used the universal. Yeah it's half the price, I'm a cheap ***. Thanks again everyone I appreciate all the help.
