Unfortunately, I am stuck with a Performance's Shop mistake.

They replaced my Stock cats with aftermarket performance ones and managed to break what I believe is the Air fuel ratio sensor 1.

From the service manual:

P1148, P1168 CLOSED LOOP CONTROL

P1148

Trouble diagnosis name
Closed loop control function (bank 1)

DTC detecting condition
The closed loop control function for bank 1 does not operate even when vehicle is driving in the specified condition.

Possible cause
Harness or connectors (The A/F sensor 1 circuit is open or shorted.)
• A/F sensor 1
• A/F sensor 1 heater

Can someone chime in and tell me what this means? From the looks of it my Air fuel ratio sensor (bank 1) needs to replaced? Is this the Air fuel ratio sensor that is located on the passengers side header?

How easy is it to replace this sensor? Can I DIY?

Thanks
