That engine has 2 of them.
If it's a V-6 engine it will have 2.
yes, it does have Oxygen sensors
How many oxygen sensors are there for a 2001 Chevy Tahoe 5.3L
That year used ONLY 2 sensors and there up close to the engine in the exhaust system/pipes.
There are 2. one just after the engine and one after the cat converter.
most o2 sensors are located on the exhaust manifold or just below on the pipes itself ,but mainly depends on the engine.
There are approximately 2 oxygen sensors on a 2005 Chevrolet Astro van. The oxygen sensors can be purchased at stores such as NAPA.
It has 1 O2 sensor on the exhaust manifold behind the engine
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 check engine light would illuminate and the code(s) would point to one or more of the O2 sensors.
They are screewed into the exhaust pipe / pipes. Start at the engine and work your way back to the muffler. There is only 1 on that engine, It will be up close to the engine.
