Hey guys I would like to get some advice on how to get rid of this engine light, I am getting a P0135 code which is the 02 sensor i guess. Would simply replacing the sensor remove this code?

Does it matter what kind of sensor to get?

For example there are some cheap ones on ebay.

Car has 70 000 miles on I don't think sensors have ever been changed. No other codes are being thrown.

What else can I do if a new sensor does not work??

Thanks
