I keep getting a scanner reading of P0051 which is : Bank 2 Sensor 1 is bad. Everyone one, including the Nissan dealerships have given me different answers as to where this sensor is located. My 2003 Nissan Frontier, 3.3L crew cab, auto trans, 2WD, non supercharged truck needs this sensor changed. Can any one give a location? Some say the 'bank' is in front of the firewall. Others have told me that the 'bank' is divided left and right , down the middle of the engine. Conflicting answers are driving me nuts !!
