P0037 HO2S Bank 1 Sensor 2 Location?
My check engine light has come on a couple of times over the last couple of weeks. Each time, I have checked the code and it is P0037 "HO2S Heater Control Circuit Low Voltage Bank 1 Sensor 2".
Can't find much info on where to find this sensor. Only thing I could find is on the V6 Camaro Bank 1 is the passenger side. But I don't know where Sensor 2 would be. I may have read that there are 3 sensors on each bank...two before the catalytic converter, and one after? But nothing definitive. If anyone can point me to where to find this sensor, I need to check it and the wiring harness going to it for a short or other problem. Thanks, Tom |

Ok, I think I found it. Instead of deleting the post, I thought I'd post for others.
For the V6, the #1 cylinder is on the passenger side. That is Bank 1. And then I found the replacement guide in my online State library Chilton manual. It says this sensor is on the "right" side. That's the passenger side. Sensor 2 is downstream (after) the catalytic converter. The attached image is a screenshot from the Chilton manual showing the location of the harness for Sensor 2. Now I have to see what's wrong with this sensor... Tom |

If you've added an exhaust upgrade or altered the exhaust,look for wires/harness touching and or melted on exhaust. Maybe bad connection at plug. Maybe something on YouTube as to how to test sensor? Good luck

I do think there may be another issue at play here, maybe a short in my harness somewhere. This may just be the prime suspect. I did find some Youtube videos on how to test the sensor; looks pretty straightforward, thanks! Tom |

Heater circuits go out all the time, you can check resistance on the heater circuit with a multimeter if you disconnect the sensor. The heater element is whichever 2 wires are the same color. But most likely you'll need the sensor. Bank 1 vs Bank 2 is just which side of the motor, sensor 1 is in front of the cat and sensor 2 is always afterwards
