If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
Depends on which engine it has and what year it is.
Haynes makes a manual with the wiring schematic for the O2 sensor on a 1991 Chevy Blazer S10. The manual can be found at most book stores.
There is more than one O2 sensor and they are all threaded into the exhaust system at various points.
A short to ground. Check wiring/sensor for damage.
That would be the O2 sensor after the catalytic converter.
There several O2 sensors on that vehicle and they are all threaded into the exhaust at various points.
No, the O2 sensors are out of the "loop" until the engine warms up.
Assuming this is a V-6, bank 1 sensor 1 would be the first O2 sensor in the exhaust on the drivers side of the engine.
It doesn't have an O2 sensor in the intake manifold. O2 sensors are located in the exhaust system at various points.
To change an O2 sensor you need to disconnect the wiring harness from the sensor. Use an O2 sensor socket and ratchet set to remove the old sensor and replace with the new one.
what is the wiring diagram for the o2 sensor on 2000 s10 blazer. it has 4 wires. what what do they all do /
That should be the O2 sensor just before the catalytic converter.
