How do you wire a universal oxygen sensor in a 2000 Vitara 4-cylinder 2.0?

Answer 1

Universal O2 sensors are easier to replace than original parts. When you determine which O2 sensor needs to be replaced, cut the bundle of wires (4 wires total) close to the O2 sensor itself. Remove the old sensor. This may be a little difficult as the heat from the manifold/exhaust can fuse the 2 together. Place a little grease on the threads of the new part, careful not to touch the sensor with your figers. Tighten the new part into the manifold. The new O2 sensor should have 4 wires just like the old one. If you are using a Bosch part, the wires are color coordinated for you. Black to black, white to white, gray to gray. Cut about 3/5 inch off of each sleeve, exposing the wire, and splice together. Use the capsule unit provided with the new O2 sensor to keep all the splices within a contained unit. If it did not come with one, use electricians tape to tape each wire set individually, then as a whold group. Make sure it is taped and encased well enough to keep elements out of the wiring. Once everything is together, secure the loose O2 wires to the chasis or other parts, keeping it away from hot and moving parts.
