P0032 code

Hey
I recently bought a 2001 S80, couple off weeks later my check engine light goes off, it is a P0032 code which from my understanding leads to the heater circuit in the upstream o2 sensor. I have checked the wiring to the o2 sensor which read 8,5 volts, the resistance on the sensor was about 3.0-3,5 ohms. From what i heard it should be around 1 ohm at 20 degrees celsius. Could that increase in resistance set of the CEL?

If you do replace the sensor, go for the same brand and direct plug-in connection that is OE to your car. (Plug-n-play) These car's often don't like the generic sensors that come with pig tail wires and require the connector to be spliced on. You likely have Bosch or Denso brand as the OE.

I have found decent O2 sensor prices at these guys:
