You have several on that vehicle and they are all threaded into the exhaust system at various locations.
unscrew it
The 93 model does not use are even have a MAF sensor.
o2 sensor
were is the fuse located for the O2 sensor
where is the o2 sensor located on a 1992 Chevy s-10 4.3 ?
on the exhaust pipe one forward and back.
it's a 5.3 litre v8
there should be a couple of them screwed into the exhaust system.
It has 2 in the exhaust pipe/ pipes. They will be up close to the engine.
Bank 1 on a Chevy is the drivers side. Sensor 1 is located in front of the catalytic convertor and sensor 2 is after the converter. Each side has 2 O2 sensors.
well on a 93 i would suspect u only have one which normally is in front of the catalytic converter on ur exhaust piping Engine-------o2 sensor--catalytic converter----muffler--exhaust tip in that order
The O2 sensors that are the closest to the engine will be the up stream ones. The ones that are further away from the engine are the down stream sensors.
