i just scraped of a part of my rear o2 sensor. now i see why being dropped sorta sux. can i just buy and 02 sensor and splice the wires to avoid a horrible install?

 

Actually it's not that bad to complete unplug, unsnap, and rewire the whole thing up. I did it when I removed my y-pipe because I didn't want to splice wires. It will take you 20 extra minutes max once you have the car up.

splicing those wires is quite hard , becouse they are stiff like guitar strings !!!!
learned that when i tried to splice mine.

you could get "butt connectors" and try to crimp them nice anf tight and finally use some electric tape around it.

but warning though - did mine that way and it only lasted 3 weeks , finally bought two new O2 sensors and got it fixed the rifgt way

jerry rig is ok for temporary fix , but do it right the first time

thanks maybe i'll have to do the hole thingy then, looks like a beotch since the rear o2 sensor wires look they run into the body, really weird

 

the rear o2 sensor wire goes through a rubber grummet in the floor and resurfaces under the driver seat, near the center console, and ends with a connecter, which facilitates the replacement.

 

how do i get to iot from the inside?

 

From under the driver's seat. The carpet has a slice in it to allow to reach the connector. You'll have more room to work comfortably if you remove the drivers' seat: held by 4 bolts : one at each corner.

 

Jack up your car. Pull out the rubber grommet. Unclip the plastic holder and pull out harness. 4-5" latter there will be a plug. Unplug old and in with the new. Put it back and your done. This takes about 5 Minutes.

 

do i get an upstream or downstream o2 sensor

 

I tried soldering my wires one time but it didn't work because they're stainless steel wires, not copper.

I ended having to buy a new O2 sensor from the dealer.

 

that depends on the ecu code you read. each o2 sensors malfunctions have their own unique codes.

 

07 07 . . .. . .

 

Downstream = Behind Cat
Upstream = infront of Cat

 

thansk so which one is the "rear heated 02 sensor"?????

 

That would be the one after the cat. There are three. You need the third.
