P0051 NISSAN - Air Fuel Ratio Sensor 1 Heater Bank 2 Control Circuit Low

Possible causes

- Faulty Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1
- Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 harness is open shorted to ground
- Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 circuit poor electrical connection
- Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 circuit fuse
- Faulty Engine Control Module (ECM)

P1168 NISSAN - Closed Loop Control Function Bank 2

Possible causes

- Faulty Air Fuel Ratio Sensor 1 Bank 2
- Air Fuel Ratio Sensor 1 Bank 2 circuit is open or shorted
- Air Fuel Ratio Sensor 1 Bank 2 circuit electrical connection

Those are both codes for Bank 2 Sensor 1. I would clear the codes and see if they come back.

need to figure out location of this sensor, is their some kind of diagram to go by?

Pretty sure Bank 2 Sensor 1 would be the front sensor on the left bank, or driver's side of the engine.

I'd have a read in the manuals we have online here, should help.
