I have a stock 2006 liberty with V-6, automatic, 4x4.
The check engine light came on and it gave codes for EVAP leak & 1/2 o2 sensor, I don't think they are related.
I replaced the 1/2 o2 sensor (NTK) & gascap. I cleared the codes & drove it.
It then gave a P0133 code for, "the 1/1 o2 sensor is sluggish".
I had a Mopar sensor for the 1/1 o2 on the shelf because I had a code a couple years ago & ordered it, but the code went away before I installed it.
I installed the 1/1 o2 sensor I had & cleared the codes & drove it.
I still get a P0133 code after a few trips, so I want to check the heater circuit.
I have a fsm, but I think it is for a different year because it shows a relay for the downstream o2 sensors.
My PDC has a spot for the downstream o2 sensor relay, but it is empty.
My fsm thinks the fuse in hole 16 feeds the o2 sensor heaters, but it in empty on my PDC.
My question is: Could someone confirm for me how the o2 heaters are controlled in my 2006 kj?
Is there a fuse in the o2 heater circuit?
It is -2degf here & I am doing this in my driveway.
