O2 sensor issue

[Pierre Petry]

Hi everyone. 2011 SHO. CEL went on and checked the codes. Had 3 P150 codes, Bank 1 sensor 2.
Replaced the O2 sensor. Was ok for maybe 3 days but CEL came back with same sensor.
Car is running fine. Any ideas?

Have a good look at the wiring to the O2 sensor, and the connector.

p0150 is: 02 Sensor Circuit Malfunction (Bank 2 Sensor 1). Sure you replaced the right sensor? This particular sensor is the upstream sensor located on the radiator side of the engine. Very frequently goes bad due to oil contamination, usually from an oil change procedure. If one of the hoses nearby is split or cracked and is blowing out oil, over time, that could damage it as well.
