My Check Engine Light is on and the OBD-II reads out as PO141- O2 Sensor
Heater Circuit (Bank 1, Sensor 2). I have a couple of questions about this.
1--- Is the PO141 code a pretty simple and straightforward sensor
replacement or do I need to be cautious about this?
I have read so many Check Engine Light horror stories about dealers racking
customers over the coals by selling them unnecessary, expensive parts or
having to return repeatedly to finally get the right one replaced.
2--- Is this something that I could have reliably done at a local shop
instead of a dealer (at a substantial cost savings)??
