I swapped in a p28 ecu into my vx and now it's throwing out a cel light. Anyone know why it's throwing the cel light? Is it the o2 sensor?

Yep

Pull the cell and find out what it is.

VX has a 5 wire O2 sensor EX/SIs have a 4 wire.

one of the harness on the passenger shock tower is missing the white wire for the 02 sensor to go to the ecu u need to add this wire from there to the ecu and that will fix it

Is there any links or how to's on the 02 sensor fix? I tried searching but got almost 1000 posts of nothing.

Checked the harnesses, didnt find any missing white wire. They are all there. Anyone got pictures or a link? Do I have to replace the o2 sensor also?

LOCATE THE 6 PIN PLUG BELOW ON THE PASS. SIDE VX SHOCK TOWER



The wires are in the following order:

ORG/BLU BLU/GRN WHT/BLK

BLU/YEL WHT/BLU YEL/WHT

REMOVE THE FOLLOWING WIRES FROM THE 6 PIN VX PLUG

ORG/BLU - O2 SENSOR

LOCATE THE 10 PIN PLUG PICTURED BELOW THAT IS ON THE VX SHOCK TOWER



The wires are in the following order:

BRN/BLK EMPTY BLK/RED

ORG WHT ORG/BLU WHT/BLU

BLU/GRN BLU/YEL EMPTY

[b]REMOVE THE RUBBER PLUG FROM THE UNUSED SOCKET

INSERT THE ORG/BLU (O2 SENSOR) WIRE INTO THE SOCKET BETWEEN THE BRN/BLK WIRE AND THE BLK/RED WIRE. (TOP CENTER SOCKET IN PIC)

Followed that guide, removed the orange/blue wire and was going to tap it into the missing slot on the 10 pin harness but even if I tapped it in there, there was no wire on the other side. Now what? I'm still using my stock vx 02 sensor, should I replace that o2 sensor also?

why are you using a p28 ECU for a vx?

dturbo

swapped out the motor with an ex motor but still using the vx harness and o2 sensor...

I think that the VX has a 1.5 Vtec...

Ya, but its a Vtec E. It's kinda different.

probably would have been good info to put in ur first post...

If you end up needing one, i have like 3 4 wire O2 sensors...

EGfosho

i didnt see that post. if he is still using the same o2 from the vx he needs to change that. because the vx comes with 5 wires other than 4.
