Rear Oxygen Sensor -- DIY?

Discussion in 'General Motoring' started by Thomas Nickerson, Nov 29, 2006.

  1. My Saturn dealership tells me that the rear oxygen sensor on my 2003
    Ion 1 needs to be replaced; it is "not switching lean to rich". If
    anyone has done it, is this job a DIY candidate? The garage wants $191.
