1 one before and one after the convertor
On my 99 there is one on each pipe coming off of the manifold and one after the converter for a total of 3.
It does not have a fuse sorry.
It should have 4 of them.
How do you remove the dashboard fascia on a 1999 Chevy Astro?
I'm not sure, but I do believe it's 3!!!!
That vehicle has several oxygen sensors and they are all threaded into the exhaust at various points.
yes! one in front of converter and one in back of converter.
.60
The 1999 Chevy Astro horn relay switch can be found on the back of the horn. The relay switch will be attached to the horn with two retaining screws.
There are 2 sensors The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The TCM is the transmission control module and it has nothing to do with oxygen sensors!
The PCV valve on a 1999 Astro should be located on top of the valve cover. It plugs in and can be easily replaced.
