Where is the O2 sensor on a p0051?
Specific repair steps may vary depending on the model. A P0051 DTC trouble code refers to the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter.

What can cause an error code of p0031?
The power-train control module and engine control module are central systems that work with your air/fuel sensor and a variety of other electrical devices and sensors. A failure in either of these modules could affect a number of systems and cause error code P0031 or a number of other related codes.
What does the DTC code for p0051 mean?
The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0051 code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code.
Where is the O2 oxygen sensor Bank 2?
With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #1 on bank 2 (the side of the engine that doesn’t contain cylinder #1). Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer).
