P0139 & P0159 after visit to mechanic
 

I took in my '02 sebring last week to get an O2 sensor replaced after awhile with p0135 and p0138. Well just today my engine light came on and these two codes were given: P0139 and P0159.

So is this more O2 sensor problems or did the mechanic possibly mess up something?

Coupe or Sedan? What size engine?

Its a 02 convert limited. 2.7l engine.
Not mechanically inclined so I don't really know what to do other than i know what the codes read as being more O2 sensor problems.

u got one o2 sensor replaced? the 139 is for a 1/2 sensor and the 159 is for a 2/2 sensor so what one did he put in?

the one that was replaced was for the original cods 0135 and 0138 which i believe is a 1/1 sensor issue.
