If you follow the exhaust tubing that leads from the engine. It is located after the exhaust manifold and after the next pipe is bolted together. Sowhere in this area you will find one. It might have just one or it will have one coming off each exhaust header side. It just depends on the model year. Some models have one after the catalytic convertor also. Again this depends on the year. The O2 sensor will be screwed into the exhaust tubing and will have an electrical connection connected to it. If you are replacing this then spray penetrating oil on it first and let it set awhile then undo the connector and uncrew it from the pipe. Hope this helps.
There are four O2 sensors on that vehicle assuming you have a 4.3L engine. The 2.2L engine I believe has three. They are accessible underneath the vehicle and are threaded into the exhaust system. One is located on each end of the cat converter and the other ones are directly behind each bank of cylinders on the exhaust pipe. Each has a four wire harness attached that can be unplugged. I can't tell you where it is SPECIFICALLY on your vehicle, but all Oxygen sensors are on the exhaust, and most are as close to the heads as possible, usually just after the exhaust manifold, screwed into the headpipe.
one in each side of the exhaust crossover pipe and one behind the catalytic converter
The oxygen sensor on a 1994 Chevy truck is on the drivers in the exhaust pipe right next to the manifold pointed twards the cab or the transmission.
under truck passenger side before cat on top of exhaust pipe
There are several O2 sensors on that truck and they are all threaded into the exhaust system at various places.
One in each of the exhaust manifolds.
It is in the gas tank, you will have to remove fuel tank to service the pump.

Since the starter is good but will not turn the engine over when hot, check the engine for free rotation. Turn the engine over by moving the crank by hand (with the ignition off.) The engine could be sticking when hot and not be able to turn over.
Never seen one.
where is the O2 sensor on a 2002 chevy trailblazer
locating oxyegen sensorsthe censors are on the exuast pipe most likely there are 2 before the cadallitic coverters and two after
4
Depending on the exhaust system, there will be one before and one after each catalytic converter
What sensors? Be specific.
That engine has 2 of them.
If it's a V-6 engine it will have 2.
yes, it does have Oxygen sensors
How many oxygen sensors are there for a 2001 Chevy Tahoe 5.3L
That year used ONLY 2 sensors and there up close to the engine in the exhaust system/pipes.
There are 2. one just after the engine and one after the cat converter.
most o2 sensors are located on the exhaust manifold or just below on the pipes itself ,but mainly depends on the engine.
There are approximately 2 oxygen sensors on a 2005 Chevrolet Astro van. The oxygen sensors can be purchased at stores such as NAPA.
