wrong, 2 black wires are not signal wires, its for Heater circuit, the other two wires are for O2 sensor output signal.

Those he tested as signal wires are in fact heater wires that should be small amount between 3-12 ohms. Other two blue /gray wired are single wires that need to test voltage in car with engine running or removed from car and need external heater to test it's functionality. With ohm test you will just get indefinite homes.

True. Just looked at Denso O2 sensor diagram and it confirms that 2 black wires are related to heater.

I check both bank 1 sensor 1 and bank 2 sensor 1 and only the bank 2 sensor 1 is not getting any reading on the multimeter. Bank 1 sensor 1 is getting multimeter reading. So most likely it will be a bad o2 sensor on bank 2 sensor 1 right? That sensor is also called air fuel ratio sensor right? They look the same as o2 sensor but they work diffrently?

@jozefsoucik31152 жыл бұрын
you are just testing heating part of the sensor not sensor itself. Problem with your checking doesnt count if the cables (to the heater) are broken.
@user-yc7ct3ub7w4 ай бұрын
When heated oxygen sensors fail, it is NOT when its cold. The ceramic element changes resistsnce ad it heats up. Old sensors heater element becomes weak with age, does not change linerally with the others. Heated O2 sensor monitor ready test will be imcomplete, or fail. Unplug the O2 sensor from chassis, clips leads from multimeter to heater wire pins, start car and warm up. Take note of what it measured cold, and what it meadures when vehicle is warmed up. Do this for all O2 sensors. If anys value is 5% more ir kess than others, it will fail the monitor test.
