The code showed P0170 which autozone identified as the O2 sensor. They said it needs 2 of them.

The following options:
Bosch 13477 83.99 each -- OE Type 4 wire;heated; 2 required
Bosch 15738 101.99 each -- Universal 4 wire;heated 2 required
Denso 234-4672 186.99 -- OE Type
Denso 234-4201 155.99 -- Universal

My wife got the info so I wasn't there to ask any questions.

Does this sound right? After some reading it looks like the P0170 could be more than the O2 sensors such as the MAF sensor.

Where do I go from here?
