Question

What is the code P2272 and how does it differ from P0159 on my 2008 Ford Ranger 4.0L?

Answer 1

P0159 -02 sensor slow response Bank 2 sensor 2

P2279 -02 sensor stuck lean Bank 2 sensor 2

This code condition is a sensor 2 this makes it a downstream sensor or a catalytic monitor sensor,P0159 would represent a 02 sensor that has degrade when a 02 sensor degrades it does not respond to the lean and rich condition.P2279 02 sensor stuck lean, in order for a catalytic convertor to work properly it needs to go from a rich condition to a lean condition this is how it control emission when it is stuck lean this becomes a fuel control problem you willneed to check for exhaust leak that can affect the performance of the catalytic to misfire condition that does not have to code up. For P0159 suspect the harness connection of the 02 sensor as not being connected

Answer 2

The code P2272 and P0159 indicates a problem with the O2 Sensor Bank 2 Sensor 2, also known as the Rear or Downstream Oxygen Sensor in Bank 2. To repair the problem, replacing the O2 Sensor Bank 2 Sensor 2 is necessary. More information about this codes can be found at the following links:
