it is located just behind where the exhaust pipes "y" together
I am pretty sure there are 2 of them. They are on the exhaust near the engine and on the catalytic converter. Look for a single wire.
The O2 sensor is in the front of the engine. If you look at the exhaust manifold by the heat shield you will see it. It screws into the exhaust and has a single wire coming out of it running back toward the drivers side of the engine. Easy to change
The crankshaft sensor is located on the side of the block below the exhaust manifold on the firewall side of the engine. It is held in by a single bolt. Access is quite tight but it can be replaced with the engine in the car.
V6 Dakotas come with "dual exhaust manifolds". If your asking about exhaust systems, all I've seen are singles in and out or single in with dual tips (mufflers). The pipes to the mufflers is Y-pipe to single.
The Oxygen sensor that typically on MOST vehicles is the one closest to the heat of the exhaust. Since the SL1 is a 4 cylinder engine with a single exhaust manifold, check (or replace) the FRONT oxygen sensor, which is in the exhaust manifold, just above the "headpipe". It looks a little like a sparkplug, and should be the only thing in the exhaust manifold that has a wire connected.
1995 Chevrolet Astro, 4.3 V6 engine with Single Point Injection System has one O2 sensor located in exhaust pipe (between catalitic converter and the place where exhaust pipes from right and left cylinder heads meets in one pipe).
Two if you have a V6 with single exhaust. One before the cat. converters and one after. A total of 4 if you have the V8 with dual exhaust
The sensor is on the driver side of the head. It has a single wire to it.
They are before or after your precats depending on year and model. 91-93 have a single O2 sensor in the exhaust manifold, as they have no precats. I believe the 94-95 have 1 sensor before the precat, and one after to monitor the O2 in the exhaust gas. 96+ have 4 O2 sensors. Two before the precats, one on the front, one on the rear, while having two after the precats, on the front bank, and the rear bank. The precats are located after the exhaust manifold, directly before the downpipe.
If your car has the 2.5L 4 cylinder engine the crankshaft position sensor is located on the back side of the engine behind the ignition module which is below the intake manifold toward the rear of the engine. You can follow the spark plug wires to it. If your car has the 2.8L V6 the sensor is located on the back of the engine below the exhaust manifold. It has a single wire and is held in by a single screw. It is in about the center of the engine. The knock sensor is located nearby, but is screwed into the block and has pipe threads. By back of the engine I refer to the side next to the firewall.
The fluid temperature sensor is located on the left side of the transaxle. It is held in by a single bolt.
Mounted on right side (passenger side) of engine block behind the right cylinder head. It gets it's single from notches in the flywheel/driveplate
The Oxygen sensor that typically on MOST vehicles is the one closest to the heat of the exhaust.

If you have a 2.3 or a 2.6 motor, there should just be one oxygen sensor. It will be located on the exhaust manifold. On the driver's side of the motor you should see it down by the firewall. It will have a single wire coming from it.
the sensor is located behind the pulley for the water pump has one single 8mm bolt in it u need to remove pulley to get at it
Single exhaust? Look before and after the converter. O2 sensors measure oxygen content before and after flow through the converter.answerThe oxygen sensor is a spark plug shaped device that is screwed into the exhaust manifold. Answer:There is one sensor located before the cat convertor. It will be a 3 wire sensor.
coolant temperature sensor is the right of the coolant outlet line on the top of the engine when looking at while standing in front of the truck. it has a black two prong clip attached to the sensor. the oil temp switch is to the left of the coolant outlet line. it has a single black wire coming off of it.
There are 4 oxygen sensors on the 2002 Avalanche, located on the exhaust pipes directly behind the engine. You'll have to put the truck on a rack or crawl under it to see them. Two are located on the left side of the exhaust system, with one on the engine side of the catalytic converter, and one just behind the converter. There are two more on the right side of the exhaust system in the same location: one before the catalytic converter, and one after. You'll be looking for a "tap", or an insert into your exhaust pipe, with a single wire coming out of it. The wire is connected to the oxygen sensor, which is screwed into the "tap".
One on each side, on the exhaust manifolds,you can reach them from the top. Should be a single wire if its the base model. An O2 sensor socket, pb blaster, extensions, universal will be required to do this.
Start at the exhaust manifold and follow the exhaust from the manifold rearward. You will find the O2 sensors. It may be mounted right on the manifold or somewhere on the exhaust pipe. Looks like a spark plug base with a single wire attached. Unhook the wire and use a boxed end wrench to unscrew & remove/replace the sensor.
the knock sensor on a 91 camaro 305 in on the passenger side of the block, bellow the exhaust manifold. its a few inches in front of the bell housing., and has a single wire running to it. looks a bit like a temp sensor, or oil pressure sensor.
There is actually two on this car. One is on the exhaust manifold with a single wire under the hood and. One is after the cat under the car
