Please help, Downstream o2 sensor wires came apart from the connector. There are black, brown, pink, and blue wires. Can't figure out which color goes to which port. Can anyone help, please?
Generally you're going to pull all that mess out and either go to another car and cut the plug out on the car side or there are companies online that sell the car side of the plug with wires already sticking out that can be spliced and some people have the tooling necessary to pull the pins out of the plug and do that dance this is something that has been dealt with many many many times and the parts are generally inexpensive and available and if you want them rig up a sloppy splice just to see so I'm going to be along with the wiring diagram and what colors go where in a few minutes I don't have any of that information for the generation 3 and all the OX sensor manufacturers sell these universal O2 sensors that come with the layout of the wiring for your particular car no matter if Toyota or General motors.
Thank you for the reply. I was thinking about going to a junkyard and cutting one out, but there are no junkyards that has a gen3 prius. Mostly gen1 and gen2 are available at the junkyard around my neighborhood. Do you know which company sells the connectors with the layout of the wiring?
If you look through factory service info, then google (after checking the Denso application guide for the downstream O2), you can find stuff like this: (AFAIK the connector view is looking at the terminal side). Posted via the PriusChat mobile app.
