Still getting P0130 P0150 P0156 and P0136 codes
 

Ever since I replaced my oxygen sensors, I get all of the above codes. I used the correct ones per the Bosch website. Direct replacement for the front and the specified universal for the rear. Anyone knows what is going on or how I can diagnose the problem?

Before replacing them I was getting no codes but the car was running poorly, now it runs great but I get codes!!:confused:

ok, I disconnected the rear driver side O2 sensor and now only get codes associated with that sensor (0161 0141 0156) instead of all four sensors (0130 0150 0136 0156)... Not sure what that tells me yet... I will now disconnect the other rear sensor, reconnect the rear drive side one and compare.

Any ideas from you guys??

It was a faulty rear sensor (even though it was new). Replaced it, no codes.... So a bad sensor can light up all three other sensors... strange.
