Hey everyone my CEL continues to come on and off and I finally found a friend to flash the code.

The codes I am getting are P0131 which I believe is my o2 sensor and P2251 which says on the reader "negative current control."

Quick google searches on both CEL's tell me that I need to replace both front and rear o2 sensors.

However, before I go purchasing these parts I just want to know if anyone else has experienced these issues and did replacing both o2 sensors clear the CEL?

Thanks for your help in advance TM3!
