how many oxygen cencors does the 1994 Chevy blazer have
Mostly, yes.
A 1998 Chevy S10 Blazer has a total of two oxygen sensors. One is used for the upstream and one for the downstream.
It has 1 coolant sensor, 1 temperature sensor
I have a 1999 Chevy blazer 4.3 v6 we just replaced them there is three two up stream and one down stream. If you get under there and look you will find them with no problem. I'm a woman and I found them with no problem. two on passanger side one on drivers side. unless you have two catalitic converters then there is 4
It should have 4 of them.
I'm not sure, but I do believe it's 3!!!!
It depends on which engine you have. Give us more info.
