PLEASE HELP! 2002 Focus SVT Oxygen Sensors Wiring Diagram PLEASE HELP!

171 Views 13 Replies 3 Participants Last post by  pbfoot
I have a 2002 Focus SVT, a newly rebuilt engine, unfortunately, the UPSTREAM OXYGEN SENSOR's cables have been cut off, and there is a short OXYGEN SENSOR in the middle on a place where it's not supposed to go.
There is also another OXYGEN SENSOR, downstream.
I would like to find the correct wiring diagram so I can connect them properly (I still need to get the REPLACEMENTsensors PLEASE ADVISE)
PLEASE I WOULD APPRECIATE IT IF ANYONE CAN HELP ME BY PROVIDING A FEW PICTURES OF THE CONNECTIONS SO I CAN FIND THEM SINCE I CAN NOT SEE THEM ANYWHERE.
I have visited the Ford dealer but they don't have any pictures of the wiring to share with me, nor do they have a repair manual available for me to purchase, the only option offered is to submit the car to the shop so they can do it for me, unfortunately, I cannot afford to have that done at the shop.

ANYONE CAN PLEASE HELP BY SELLING A 2002 SVT SERVICE MANUAL, OR PROVIDE PICTURES OF THE OXYGEN SENSORS AND THE CORRECT WIRING DIAGRAM, IF PRICE IS REASONABLE I WILL PAY FOR DETAILED PICS.

Thanks in advance for your help

Rear 02 sensor comes out of the short engine harness. Front sensor comes out of gray connector next to the shifter underneath the throttle body. Runs over the transaxle. Splits off at crank sensor. Front 02 sensor ends at ckps and the power steering pressure switch wiring continues over the radiator support.

There is only 1 sensor sold by motorcraft and it fits in either the front or rear position. Unfortunately it is long. The rear sensor used to be a separate part number and shorter to clear the axle. The threads are 18mm. I put a 90 degree adapter on mine so it wouldn't be so close to the axle. Make sure to zip tie the sensor wires away from the axle.
The rear 02 connector. Blue. Wrapped with the alternator ug.

Short harness for the front sensor. Connects to speed sensor, back up light switch. Green is the 02 sensor. Other 2 are the crankshaft position sensor and the power steering pressure sensor. Black. Green.
I would replace the harness instead of repairing.
