Terminology Clarification
Content
DESCRIPTION:
The illustration explains the following terms:
^
Engine BANK
^
Up = Sensor 1 = Front = Closer to the exhaust manifold = Before the Catalyst
^
Down = Sensor 2 = Rear = After the Catalyst
^
Bank 1 is closer to the dash panel = RH (right hand)
^
Bank 2 is closer to the Radiator = LH (left hand)
The following 02 Sensor EXAMPLES show how to interpret the terminology:
^
B1/S1 = Bank 1/Sensor 1 = Dash Panel Side BEFORE the catalyst
