There several O2 sensors on that vehicle and they are all threaded into the exhaust at various points.
That should be the O2 sensor just before the catalytic converter.
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.
Engine coolant temp sensor, Engine oil pressure sensor, Crank sensor, Cam sensor, Bank 1 O2 sensor, Bank 2 O2 sensor (V-6), Post catalytic converter O2 sensor, EVAP (fuel system) pressure sensor, Fuel level sensor, VSS (Vehicle Speed) sensor, ABS wheel speed sensors, to name a few,
There is more than one O2 sensor and they are all threaded into the exhaust system at various points.
That would be the O2 sensor after the catalytic converter.
A short to ground. Check wiring/sensor for damage.
Where is the o2 sensor on a Mitsubishi pejero 1999, V6 GDI V75W
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.
what is the wiring diagram for the o2 sensor on 2000 s10 blazer. it has 4 wires. what what do they all do /
