Title: O2 sensor wiring Post by: smithy on September 20, 2008, 12:16:34 PM ive got a 3 wire O2 sensor which im trying to hook up but would like to know correct wiring before i get too far.
on the sensor there are 2 white and 1 black wires. i am pretty sure the black would be for earth but does it matter which of the 2 is for ECU reference and heater ( switched power). or have i got it completely ass about ? cheers dean Title: Re: O2 sensor wiring Post by: smithy on September 20, 2008, 02:44:55 PM Got it sorted ;)
for anyone who's interested..... black- ECU reference wire ( replaces single ECU O2 sensor wire) white- switched power ( heater) white 2- earth. |
