your trans am has 3 oxygen sensors one on each exhaust manifold and one after the catalytic converter
Two
it has 4 sensors two before cat and two after
There are 2 oxygen sensors.
4 in the exhaust before the cats and after the cats
I do not know for sure how many o2 sensors are on your 98 Chevy but i do no they will be mounted in the exaust mainfold(s) my 93 has only one mounted on the driver side manifold
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
Two (2). One is before the catalytic converter and one is down stream (after it.)
It may depend on whether or not it is a Z28, SS etc. I have a V6 98 and it has 3. 2 right after the headers and 1 by the cat.
All O2 sensors are located on the exhaust system. Start at the exhaust manifold and work your way backward, and count them.
No, among other differences, the 1998 has two oxygen sensors while the 1994 has one. Also the 1998 computer controls the electronic governor in the trans.
On a 1998 Ford Explorer XLT : With the 4.0 liter SOHC V6 engine ( 4 oxygen sensors , the 2 closest to the engine are used for adjusting the fuel ratio and the other 2 are catalyst monitors There are also ( 4 oxygen sensors if you have the 5.0 liter V8 engine )
Only one
