On 01 Civic LX is the primary(pre cat) O2 sensor 4 wire? If so, is it a standard Honda 4 wire sensor?

 

Yea i should be last time i did one was on my booses Aunts accord and it is a 2002 and they were a honda standard 4 wire

 

If it needs replacement, try buying a Bosch generic o2 sensor for your car. It is a simple 4-wire splicing job of your old o2 sensor harness. I had to replace mine a while back - Bosch Honda OEM o2 sensor = $300. Bosch generic o2 sensor - $80.
You do the math.
