Primary O2 Sensor not in jumper harness

[skubasteeve]

Curious if I should have my PH02S connected to my ECU with the white wire or not, I currently have an X-Series UEGO connected to D14 and reading fine

S300 v1
B20B Turbo, RC750, PT5858

Are you inputting a narrowband signal to D14?

[skubasteeve]

Nope, D14 is getting signal from the Wideband currently

[Spunkster]

You should not use D14 as it cannot see the full voltage range. Use D10 instead.

[skubasteeve]

I plan to get there, I am just curious if its necessary to have the actual PHO2S white wire connected to something.

Also, if I use D10 I have to possibly remove some resistors?

[Spunkster]

No you do not need it if you run closed loop from the wideband signal.

[skubasteeve]

I hooked up D10 to wideband and adjusted in hondata and I am only reading 18 afr... is this a symptom of needing to cut the resistors?

[Spunkster]

Is D10 still connected to its original location or is the wire cut?

[skubasteeve]

Wire was cut

Figured it out by cutting the resistors all good now
