Question about 2004 Jeep Liberty
I have a PO137 bank 1 sensor 2 and a PO138 bank 1 sensor 2 code showing on my 2004 Jeep what does this mean and which sensor is it that needs to be changed driver side, passenger side?
Well on my car these are reffering to the sensors in the exhaust, the upstream sensor(before the cat) and the downstream sensor(after the cat) the downstream sensor can act up if it is lazy or sluggish, or due to a bad catalytic converter or a clogged one. however there are sensors on the exhaust manifold which are determined by driver side or passenger,my opinion is to get a scanner for about $100 to $150 and you can figure out many of these codes yourself.
