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

^ B2/52 = Bank 2/Sensor 2 = Radiator Side AFTER the catalyst
