I got this code P0037 ho2s heater control circuit low. and i figure it is a type of O2 sensor. I'm not too familiar with this car. I've just done some of the basic maintenance, Brakes/rotors, plugs and oil. but I was wondering if anyone knew where this sensor was located? It say's bank 1 sensor 2. if any one can point me in the right direction that will save me the guessing game...

thanks

First, you didn't indicate which car or year you're asking about - if it's a 1st gen tC, Service Manual is here;

https://www.scionlife.com/tech/manual/?manual=tc05_0001

O2 sensor replacement is in section 12.

In fact, Service Manuals are available for xA, xB1, tC1 - click on Scion Vehicles in the bar at the top of the page, select the drop down for the one you need; scroll down a little, service manual and electrical guide are in the Technical Links section.

More info about this code here;

I dont have a picture of it, but I'll try to explain it to you. Standing in front of the car, looking at the engine its on the right side of the head or the drivers side. Theres a rectangle looking platform and its underneath that and it screws in from the backside of the head...the frontside should have a hose going to it.
