i switced my lsvtec crx over to obd1 and i was wondering how to hook up the 4 wire o2 what color goes where my conversion harness only has one extra wire for the heated 02.

i have a 2 black 1 green and 1 white


and also it keeps on throwing a tps code i have changed the tps but still throws the code i was told by someone u was suppsoed to switch 2 wires around is this true..

thanks

 

wondering the same thing about the 4-wire o2. with the tps, try resetting the ecu (pull hazard fuse) if you havent already done so. thats all i can think of.

 

yea i tried resetting the ecu it didnt help....

 

4 wire O2

black=connect to switched power
black & green=splice together and connect to ground
white=O2 sensor lead wire, connect to ecu

 

At the TPS, you switch the Green/White with the Yellow/White. Once swapped, the Green/White will be at Pin 1 and the Yellow/White at Pin 3.
