no. the upstream sensor is the one before the catalytic converter and the downstream is the one after

Are all four oxygen sensor the same in your suburban 2000?
No. Upstream and downstream O2 sensors are different for a 2000, 1500, Chevrolet Suburban with the 5.3 engine.
Do I get two of same sensors for the1999 explorer or are they different?
Assuming we are talking O2 sensors, the downstream O2 sensors left and right are the same. The upstream O2 sensor left side is left side upstream only. Upstream right side fits both left and right sides upstream only. The difference is the length of the wires for the upstream sensors.
Can you wire two oxygen sensors to the same wires to get rid of my check engine light?
NO, you cannot do this, this will compound your problem and eventually damage the engine and/or catalytic converter to the point that they/it must be replaced, all three failures are very expensive repairs. The faulty O2 sensor must be identified and replaced. There are 4 set-ups: Single sensor; Dual "upstream" <both sensors are pre-cat>; Dual upstream/downstream <one sensor is pre-cat, one sensor is post-cat> and Quad sensor <two sensors are pre-cat, two sensors are post-cat>. The upstream controls the fuel mixture and the downstream monitors the catalytic converter. BANK 1 is always the number 1 spark plug side and SENSOR 1 is always upstream. Once the fault is corrected the ECM must be cleared with a scanner to shut off the light.
How many oxygen sensorsare there on a 1995 intrepid 33l If two is it the same type sensor?
Well, on my 1996 'trepid with the 3.3L, there are four sensors. [Note - My 3.3L is equipped with the California Emissions so it may be different] The upstream sensors are the same, but they differ from the downstream sensors. Considering that the catalytic converters for the 1995 and 1996 are the same, I would expect you to have the same number of sensors.
What would happen to a boat that was moving upstream at the same speed as the current moving downstream?
The boat would make no progress.
Is the bank 1 sensor 1 o2 sensor on a 97 Chrysler lhs upstream or down stream?
Bank one is the same side as cylinder number one. Sensor one is upstream or before the catalytic converter.
What is the difference between DSL and ADSL?
ADSL is simply a version or 'flavour' of DSL. The 'a' refers to asymmetric, meaning 'not the same'. Hence, ADSL usually has different downstream and upstream rates (e.g. 1536/256 is a common speed of ADSL available in Australia, where downstream the link speed is 1536kbps and upstream is 256kbps).
If Tina swims 4 miles upstream at 1 mph and back downstream to the same point to the same point at 4 mph what is her average speed?
8 MPH
Why does the idle speed accelerate then go back down after a few seconds on 96 gmc sierra?
I have the same truck model and had the same problem. It is the oxygen sensor either the upstream or the downstream get a check engine test its free and then you'll know whether its up or down either way they cost a pretty penny. let me know. This also causes the truck tonot burn the gas properly and the truck loses force.
Where is the 02 sensor on 2001 gmc seirra?
If the 5.3L is the same as my 4.8L, which it probably is, there is one located upstream from your catalytic converter, and one located downstream of your catalytic converter. They are not that far from the cat. There is 2 on each side; 1 set for each catalytic converter. 4 in total.
Where is the downstream O2 sensor bank 1?
It is after the catalytic onverter on the same side of the engine as cylinder #1.
Is an oxygen sensor and fuel temperature sensor the same sensor on a 2002 dodge stratus?
No.
