Oxygen Sensor Replacement

[pns0ccc]

I'm pulling a code 157 (Bank 2, Sensor 2, Low Voltage). According to the service manual it may be necessary to lower the exhaust system for access/removal of the HO2S. Has anyone replaced the Sensor without lowering the exhaust?

its a little tight but do-able. i bought the 02 sensor removal tool. i think it fits on a 3/8th rachet. which made it a little easier. replace both while your down there so your done with it.
