I have a check engine light, had it read at local auto shop.
I have a '97 3.8 ltr.

Codes came up as
P0102 MAF sensor-circuit low
P0141 O2 Sensor- perf bank 1 sensor 2

I pulled the MAF sensor out and cleaned it with MAF cleaner...

Where is the O2 sensor located? In front of the cat or behind? which side?

Thanx for the help.

 

P0141 is the O2 sensor that is just before the cat.

 

thank you

 

Is it possible to just wire brush an o2 sensor clean or will that damage it?
