there are 2, upstream which is under the exaust manifold flanges and the downstream which is in the exaust pipe
The oxygen sensor is mounted in the exhaust down-pipe
The 2001 Ford Ranger 4.0 liter V-6 engine map sensor is located on the firewall in the engine compartment. The map sensor will be on the drivers side of the firewall.
its is located downstream on the backside exhaust manifold
There are 2 in the Y pipe one behind the cats and one on the air inlet tube between the air box and intake manifold
it is the upper stream o2 sensor before the convertor
behind the catalytic converter
It is the one after the catalytic converter?
In the Exhaust manifold at the front of the engine
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.
That is the oxygen sensor screwed into the downstream side of the catalytic converter.That is the oxygen sensor screwed into the downstream side of the catalytic converter.
daewoo lanos oxygen sensor is located at the front of the engine approx in the middle of the outlet manifold as enclosed pics confirm:
As far as I know, there are 4 oxygen sensors on a 2001 Hyundai Santa Fe. 1 upstream sensor and 1 downstream sensor located in the front manifold/exhaust and 1 upstream and 1 downstream sensor located in the rear manifold/exhaust.
