I just got a P0141 or Downstream O2 sensor heater circuit malfunction.

Am i right in thinking I can let this go for quite a while whitout any driveability problems?

Thanks in advance.

this came up last month and i do not know the answer. i think you are correct since the rear sensor is primarily a monitor only, it just reports that the cat is there and working correctly.

 

but that aside, there are now 13 threads with p0141 in it, all but one of them was posted in the cold 6 months of the year, most dec - mar. there is a chance that this could be an electrical connection corrosion problem. maybe due to salt on the roads. especially considering it is reported as a "circuit malfunction". i'd check that first.

 

any chance you live in the snow / salt belt? :lol:

Salt belt? No. I would call that brine soup if you want to know the truth!

You're probably right about the corrosion. I will wait for warmer temp before I have a look at it.

Have a good day.
