Where is the o1 sensor on a chevy blazer - 2001 Chevrolet Blazer

Answers :

Did you mean O2 sensor - there may be two oxygen sensors on the exhaust - one is usually close to the engine on the exhaust manifold or just beyond and the other should be on the Catalytic converter - looks like a spark plug going into the exhaust and a wire attached. - although not all vehicles are equipped with two. Inspect wiring before replacing - GM is recommended to replace with GM only - aftermarket O2 sensors don't last long.\012
This is general info.
Good luck.
