'01 Infinity I30's have 4 O2 sensors. Two in Bank one and two in Bank two. They are located on the exhaust system. On the front of your engine you will see four harnesses, blue, red, white and black. All but the blue wire runs under the engine to the exhaust system. Bank 1 is the rear of the exhaust and Bank 2 is the front of the exhaust (by the manifold). Black and white go to Bank 1 and blue and white go to Bank 2. Go to infinitihelp/Ownership/common.com and there is a diagram of the exhaust system. Your most likely looking for the black harness/wire.
The 2001 Infinity intake valve timing control position sensor is located on the back and of the head. The sensor should be labeled as such.
The oxygen sensor is mounted in the exhaust down-pipe
its is located downstream on the backside exhaust 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.
where is the pcv valve located at and what does it look like on a 2001 infinity qx4?
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.
