P0037 Error - GX470

[stoshzack]

Hi All -

Hoping that someone can help me figure this out. I was driving the other day when my VSC/trac/engine light came on. I went home and pulled the code. I had a P0037 error. I just assumed it was the O2 sensor, so I pulled and replaced with a new Denso. Drove it around again and got the same error. I went back and checked the voltage to the sensor (around 9.5 volts), and check the ohms on the sensor itself (around 16.5; I seriously doubt a new Denso would be bad, but checked it anyway). I cleaned the connection and plugged the sensor back in. I got the same error driving around again today.

Anyone have any thoughts on what to do next?

Thanks for any help.

I guess I should add that the sensor replaced was the passenger side after the catalytic converter.

I think I figured this out. Looks like Bank 1 = driver side for V8 (and not passenger side as I thought).
