Just wanted your thoughts on this one, before I go throwing a rear sensor at it
I have fault code P0141 on this vehicle, I have cleared it several times over the last few months but will come back at random, sometimes a month or two weeks
The MIL came back on yesterday and this is the Freeze Frame data
I have measures the resistance on front and rear sensors and I have 15 ohms on front and 16.9 ohms on rear, so the heater circuit of the rear sensor appears to be ok
I have done an emission test and have CO 0.0 and HC 10 with Lambda 1 so the cat appears to be working ok
The other thing is that the rear sensor appears to be switching
I would have thought the rear sensor signal should be a little flatter
So I am wondering now if its a random supply voltage problem to the rear sensor, or ECU fault
Any ideas as to how i can move forward on this
Many thanks
Peter
PS: Both front and rear heaters are supplied from fuse 19, front one has not logged a fault so I would imagine the rear sensor is getting power the same as the front
