On a 1997 Chevrolet S-10, the O2 heater circuit bank 1 sensor 3 is typically located in the exhaust system. Specifically, it can be found downstream of the catalytic converter, often near the rear of the vehicle. This sensor monitors the oxygen levels in the exhaust gases to help optimize engine performance and emissions. Always refer to a repair manual for precise location details and procedures.
If it is saying that the heater circuit has failed then this O2 sensor has failed. The o2 sensors have tip heaters in them. These are irreplaceable. Replace the whole sensor. This particular sensor is located on the driver's side exhaust in front of the Catalytic Convertor.
Bank 1 is the bank of the engine that contains #1 cylinder. Bank 2 is the other bank. Sensor 1 is located before the catalytic converter. Sensor 2 is located after the cat converter.
Bank 2 locates on the opposite side of the cylinder # 1 and the sensor 1 is locates in the front
left side of the engine after the cat
It is the sensor that is screwed into the exhaust manifold on the back of the engine.
