Engine Bank Identification
An
OBD Scan Tool
will usually identify Oxygen (O2) Sensors by the Bank Number (B1 = Bank 1; B2 = Bank 2) and Sensor Number (S1 = Sensor 1; S2 = Sensor 2, etc.). Bank 1 is not on the same side of the engine for every vehicle.
Bank 1
will always contain Cylinder 1. To locate Cylinder 1,
Check for cylinder labels on spark plug wires
Look for the cylinder that is closest to the front of the engine
Refer to your
Repair Manual
(Found under 'Literature')
Bank 2
refers to the bank opposite Bank 1
Sensor 1
refers to the sensor before the catalytic converter
Other Common Terms:
Upstream Sensor, Pre-Cat Sensor
Sensor 2+
typically refers to the sensor(s) after the catalytic converter
Other Common Terms:
Downstream Sensor, Post-Cat Sensor
Common O2 Sensor Locations
Vehicle and part manufacturers sometimes use different terminology than diagnostic tools to identify sensor positions. Regardless of the vehicle's engine orientation, the right or left bank is determined by viewing the engine from the rear (opposite the drive belts).
A
Upstream Sensor
(Before Converter)
B
Downstream Sensor
(After Converter)
C
Left or Front Upstream Sensor
(Before Converter)
D
Right or Rear Upstream Sensor
(Before Converter)
Common O2 Sensor Contaminants
Oxygen (O2) Sensors commonly fail due to contamination. When checking or replacing an O2 Sensor, visually inspect the sensor body to determine if it has been contaminated by a faulty part or substance upstream, and correct the fault before replacing the sensor.
ANTIFREEZE POISONING
Common Causes:
Cracked or warped cylinder head
Leaking cylinder head gasket
Leaking intake manifold gasket
Antifreeze Poisoned O2 Sensor
SILICONE POISONING
Common Causes:
Use of an improper silicone gasket sealant on the engine
Silicone Poisoned O2 Sensor
CARBON BUILDUP
Common Causes:
Clogged air filter
Leaking or defective fuel injector
Carbon Buildup O2 Sensor
