o2 Sensor values.

Post by scanboltron »

Hey guys

Having some trouble diagnosing some codes.

Ran a multimeter test on my up and downstream o2 sensors. Got 4 and 6 ohms on front and rear sensors. But cant find what the range ohm vaulie should be online anywhere. Does anyone know what they should be?

Im running a 99 v70 wagon base non turbo.

Thanks in advance for any help.

They are in a proper resistance range,but that can't be a pointer are they working good or not.
Live data from them can only point you to right direction.

Yeah get some live data on them. Mine (which as far as I know are functioning as-intended) fluctuate between about 0.2volts and 0.8volts while cruising. Readings usually bounce around in my OBD app (using OBD fusion for iPhone).
