redtop o2 voltage??

[mrnissan]

ive been trying to track down my richness problem (wideband reads 12.1 at idle) i think it may be a o2 issue im using the fat o2 from the blacktop and now im seeing mixed reviews where people are saying u must use the skinny o2 or it wont read correctly my question is how many volts or mv should the computer be recieving at idle for a stoichiometric reading?

Only Red Tops use the skinny's

Black top SR's (even S13 B/T) use Fat type O2

Get the correct one

i was thinking that was the problem anyone elses input before i go ahead and buy a new o2?? do the redtop skinny o2's give a different reading then the blacktop fat o2's?

[mrnissan]

anyone??? does the o2 in the redtop read from 0-5v????

No. It is a narrowband O2 that reads from 0.0v and .999v while switching back and forth from rich to lean.

if you have a redtop ECU you will need skinny o2 sensor.
if you have a blacktop ECU you will need a fat o2 sensor.

They do not read the same.
