In the exhaust pipe in front of the catalytic converter...close to engine in crossover pipe
Turn off with the temp button, BUT HOLD FOR 5 SECONDS, it should change
The answer is debated amongst geologists, astrologists and palaeontologists - the earliest period in life's history is the Archean eon, when the first proto-cells were thought to have formed. The earliest period there, is the Eoarchean - 4200 - 4400 million years ago. However, the earliest eon is the Hadean, which encompasses the formation of the Earth as celestial body 4600 million years ago, up to 4200 million years ago. The earth was formed by accretion (gravitational attraction of smaller bodies, to form a central object of greater mass, thus attracting more smaller bodies, and so on), within 10 - 20 million years, so, other than describing this period of Earth's history as 'Proto-Earth', there isn't really a way of classifying even earlier stages, unless you are willing to look into the stages of accretion in forming planets. (The earliest stage would probably be a 'proto-planetary disk' stage, which was itself formed as a by-product of the formation of the sun, followed by a kilometre-wide planetisimal, and then a Mars sized 'embryo', growing progressively. In this sense, the Earth and the Sun are descended from the same Giant Molecular Cloud, or GMC.)
behind the cat
The GMC S-15 became the GMC Sonoma in 1991.
were is csp on gmc sonoma 2.2
where is the iat sensor located on a 2003 gmc sonoma truck
The Oxygen Sensors on a 2003 GMC Sonoma are located in the exhaust system. There is one Oxygen Sensor located where the two manifold pipes come together before the catalytic convertor. There is also another Oxygen Sensor located just behind the catalytic convertor before the tail pipe.
There are several 02 sensors on that vehicle and they are all threaded into the exhaust system at various points.
The MAP Sensor on the GMC Sonoma is located in the engine compartment just to the left of the alternator. The MAP Sensor is usually colored silver or shows a gold tint.
Assuming the engine is a 4.3L, bank 1 would be on the drivers side.
in the fuel tank
To change a fuel vapor sensor on a 1997 GMC Sonoma you need to disconnect the wires that are holding it in place. Next, remove the old sensor and replace with the new one.

The camshaft sensor is located inside the distributor.
