First time it was p0158,p1147,p0139...then 2 weeks later it was p1147,p0139...and today it was only the p0158. Now I have one of my 2 rear O2sensors installed on my b-pipe and the other installed on the y-pipe. Could this be a reason for these codes? I would attempt to fix the problem if the codes were the same everytime. What the he!! do I do?

You have to have the rear 02s mouted behind the cat. Also, if you have an exhaust leak....that doesnt help

The P1147 and P1167 codes mean that the sensor is bad. If you get either of those codes, you need to replace the sensor. The P0138 and P0139 codes can be fixed using several methods, but because of the P1147 code, you need to replace the sensor.

Trust me on this one, as I spent alot of money and time figuring it out on my car. E55AMG2 can back me up on this one, as he was there as it happened.

reset the ecu and wait until the ses light comes back on then rescan it again maybe that will narrow it down...

indeed, O2 sims came to save the day.

So you ended up changing a sensor and adding the simulator?

You can cure the P0138 and P0139 codes with a sim, but for P1147 or P1167, you'll have to replace the sensor.
