i just put an ls in my rex and im getting an o2 sensoe code
my question is, are there 2 o2 sensors on the ls motor or just one like the old d series?

if its an obd0 motor then i think its just one single wire o2 sensor, but if you have an obd1 b18a1 or b18b then you need a jumper harness to wire in a 4 wire o2 sensor

Re: (jayturboef)

i replaced the o2 sensor but the light came back
i was using the pr4 but i had a pm6 so i slapped that in there and now the light doesnt come on.
could it be my ecu?
