SOURCE: PO137, PO 138 codes

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.

SOURCE: recurring codes

these code could have come up due to a mismatch in the test equipment used to recall them try using another test rig to retrieve the codes you may find they are not there anymore, i have had this when using the incorrect lead on a system i have checked my computer and there are no codes like that for the car you state

hope you find this useful regards JR
