Where are the oxygen sensor for a 2002 explorer?

There is a total of 4 oxygen sensors the 2 upstream sensors are located right below the exhaust manifold flanges and above the upstream catalytic converter.The 2 downstream sensors is located in the exhaust pipe,right behind the upstream catalyst,and ahead of the main catalyst.


Where are the O2 sensors located?

All O2 sensors are threaded into the exhaust system at various points. Upstream O2 sensors are located before the catalytic converter(s) and downstream O2 sensors are located after the catalytic converter(s).


What is upstream and downstream o2 sensors?

upstream 02 sensor located right above exhaust manifold gasket downstream located right in front of catallytic converter


What is difference between upstream and downstream in relation to oxygen sensors on vehicles?

Upstream will be the closest to the engine, and are used to sense the air/fuel ratio and tell the computer how much fuel to inject. Downstream sensors are used to verify the upstream sensors and convertors are functioning correctly, so they are located after the convertors.


Where is the o2 sensor on 98 ford mustang v6?

There are 2 or 3 oxygen sensors in your exhaust. "Upstream" sensors are located between the exhaust manifolds (headers) and the catalytic converter (usually located on the mid-pipe); "downstream" sensors are located after the catalytic converters. On V6 Mustangs there can either be one or two upstream sensors and usually only one downstream sensor.


O2 sensor location on 2005 mustang?

Where is the upstream and downstream oxygen sensors located on a 99 dodge stratus?

before and after catalytic converter.


Where is the oxygen sensor in a 2001 Hyundai Elantra?

The 1996-2001 Elantra's have two sensors the upstream and downstream the upstream sensor is located the exhaust manifold and the downstream is located behind the catalytic converter.


Where are the 02 sensors on a 2006 Cadillac dts?

On a 2006 Cadillac DTS, the O2 sensors are located in two main areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream O2 sensors are positioned on the exhaust manifold, while the downstream sensors are located on the exhaust pipe after the catalytic converter. Typically, there are a total of four O2 sensors—two for each bank of the engine.


Where are oxygen sensors located on a Ford Windstar LX?

There are 2 oxygen sensors one upstream and one down stream. Both oxygen sensors are located underneath the van. The down stream oxygen sensor is located behind the cataylic converter near the cross pipe and the upstream oxygen sensor is located in front of the cataylic converter in plain sight. They look like spark plugs with either 8", 12", or 14" wires attached to them. The upstream oxygen sensors is easily located underneath the vechicle to the front. The downstream oxygen sensor is not the one lcoated on or close to the cataylic converter.


Where is the 02 sensors located on 96 Lexus LX450?

On a 1996 Lexus LX450, the O2 sensors are located in two primary positions: the upstream (pre-catalytic converter) sensors are situated on the exhaust manifold, and the downstream (post-catalytic converter) sensors are located on the exhaust pipes after the catalytic converters. You may find the upstream sensors closer to the engine, while the downstream sensors are further along the exhaust system. Always ensure to follow proper safety procedures when working on vehicle components.


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.
