Just replaced the front and rear O2 sensors and now I'm getting the following error codes:

P0159 - Bank 2 Sensor 2
P0150 - Malfunction Bank 2 Sensor 1
P1174 - Fuel Air Metering Manufacturer Control
P0174 - Bank 2 System 2 Lean

Not sure what the deal is. 02's swapped out easy enough. I covevered up the melted split loom on the leads. Made sure nothing was melted (on the wires) and cleaned them with contact cleaner and reassembled.

Started it up, let it come up to temperature and ran it down the road for 100 miles and it ran great then almost as soon as I turned the corner to the house, the CEL came on and spit out these codes.

I doubled checked everything and it looks 5x5 disconnected and reseated the the 02 sensors and reset the codes. It's off for now, but I expect it to light up again tomorrow.

Any idea? Need a young priest and an old priest?

 

Where did you get the sensors from? Are they the universal kind or the plug and play? Also are you sure about P0159? I can't find it. Also recheck the definition of P1174 think that is another lean code.

 

Did you put them in the correct spots?
If I remember right they are location specific but I cannot confirm this.

 

They are location specific for front and rear. Can't mess them up. The connector is different. I got them from Atlantic British

 

I've gotten 2 bad O2 sensors from AB this year. Get a good scanner and check out the actual voltages.
