How do you tell if an oxygen sensor is upstream or downstream on a 2002 Chevy silverado 1500?
Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
Is the upstream oxygen sensor the same as the downstream oxygen sensor?
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
Do you need upstream or downstream oxygen sensor?
Depends on what the problem is or what code was set.
Where is the oxygen sensor located on Plymouths?
There is an upstream and downstream o2 sensor. The upstream is loctaed in the exhaust manifold before the catalytic converter. The downstream is located behind the catlytic converter.

How many 0 2 sensors are in a 1997 Ford Expedition Eddie baur?
I believe there are ( 4 ) Bank 1 is the passenger side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) Bank 2 is the driver side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) The 2 sensors before the catalytic converter are used for air / fuel ratio for the engine The 2 sensors after the catalytic converter are called catalyst monitors
Is the bank 2 sensor 1 on an 2000 Infiniti I30 upstream or downstream?
Sensor 1 would be UPSTREAM before the exhaust enters the catalytic converter
What is the difference between bank 1 sensor 1 bank 1 sensor 2?
Sensor 1 would be before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
Were is the oxygen sensor located on a 2005 Chevy impala?
There is 1 before the catalytic converter and 1 after it. The 1 before is called the upstream and the 1 after is the downstream.
Where is the bank 1 oxygen sensor on a 2002 ford explorer located?
Bank # 1 is the passenger side of the engine Sensor # 1 is before the catalytic converter ( upstream ) Sensor # 2 is after the catalytic converter ( downstream )
Where is the downstream oxygen sensor on a 91 ford ranger 2.3 liter engine?
It just has ( 1 ) oxygen sensor , before the catalytic converter ( upstream )
