O2 sensor wire repair

[@mikewinkker4897]

Most people don't even touch their car car much less fix them .thankyou for helping those soles who want to try by showing them how .you are amazing dude .rock on bro rock on .

[@YellowVette04]

Looks like your O2 sensor connectors are the same as mine (2×2 connector). I initially got the wrong O2 sensor extensions (1×4 connector) from TSP when I ordered my headers and would have given them to you. Nice quick fix and you know you ain't gonna fix it until the O2 sensor goes bad lol.

O2 sensors are a pain in the neck, back, wallet.....

[@MrRandomeness87]

not sure if anyone would read this but where would you buy wires for the o2 sensor. My o2 sensor wire is okay but the wire that my o2 sensor wire is connected to is broken. Its the wire connected to my catalyic converter and im trying to trace it but it goes deeper and deeper into the car and i dont have the right tools for it. Im pretty sure if i trace it well enough, it would be connected behind my radio. If anyone reads this, some advice would be highly appreciated. Thanks for your time :)

You can buy extenders on amazon. What year, make, and model is your vehicle?

[@ifitsnotbrokenfixit1193]

Easy fix again. Need to put some heat shrink and wire lume over them wires.

[@chemicalspore]

I just need to stop being cheap and buy the right hardware

[@jasonalward4720]

Did you drive if far enough to reset your open/ closed loop?

[@chemicalspore]

Once I fixed the wiring and reset the code, the car started right up with no problems. No misfire or un-even idle

Thanks bro!!! Were you having poor mpg?

not really, it happened the same day. Car ran like total shit

Same problem change my 02 downstream sensor and still nothing change then I checked the connector part. All 3 wires where cut sumone try to fix it with tape but wires where greasy and black and burnt....Thanks for the video I will try the same thing u did. I just hope who ever did it first hooked the right wires together in the first place....I'm having idle problems and misfires I'm thinking it's all from the o2 sensor wiring.

[@chemicalspore]

Good luck buddy

[@bigdawg6476]

Did you ever fix it im having problems with my 02 sensor wiring to I put a new 02 downstream sensor and still getting p0141 code

[@jasonalward4720]

I had some warrenty work done from an after market company and i pick garage n pay $150 deductible Well they didnt secure my rear o2 wires going to my bank 1 sensor 2. Driver side rear I ran over a dead deer n ripped my pig tail right off the harness side end n now since i updated my SCT tuner via wi fi to see if any at all updates were released. My o2 wire was already ripped off at time i updated my tuner I went to remote start my car and it starts n thdn dies 5 seconds later Well my check engine light came on. My point is, if its a rear sensor. The only job is to see to read ur emmissions after your cats and if the reading is lower n cleaner than your first sensor. No dngine light cat or no cat. Thats why defoulers (sp?) Work. They take the sensor out of direct exhaust gasses. So they technically are cleaner. Your car should run ok on a rear o2 problem

[@justdissin7340]

Someone cut my brand new 02 sensor wire. I spliced them & put back but still showing check engine light. Do i need to get a new 02 sensor maybe?? It is bogging too. Would check engine light remove itself?

[@chemicalspore]

How long has the light been showing after you spliced it back together?

[@justdissin7340]

@@chemicalspore its been 24hrs now. I only drove it for 3 miles . Havent drove it because its kinda bogging at 1st when i start car. Wasnt like that before they spliced sensor. They tried stealing cat but they realized it had a aftermarket cat . So i assume they cut sensor thinking it had oem cat

Hello! I have a 08 mercedes with the code P0031, I checked my wiring and the conector where the sensor goes, five out of six cables have exposed copper, I just want to know if cutting the cables and pin the connector a little higher is safe. Thanks!

[@miguelangeldejesus8063]

*The damaged wires are very close to the connector

[@chemicalspore]

@@miguelangeldejesus8063 you might want to see about a replacement. Or if you can fix the wires, keep it away from heat sources that can melt wires. Use wire loom to help sheath and protect.

[@miguelangeldejesus8063]

@@chemicalsporethanks for the reply! I already replaced the o2 sensor thinking that was the problem but the damaged wires are the ones that run to the ECU, etc... I'm trying to pin the connector without splicing new wires

@miguelangeldejesus8063 yeah, your car will go nuts if it does not get the proper reading from the air flow

[@garnetsuss4881]

Don't buy extension harnesses, solder joints with tin/lead solder, lined shrink tube, and loom. That'll give you a more reliable connection than harnesses.

[@chemicalspore]

I bought extensions and put em in. This was temporary after i did the cam, heads and long tube headers swap

[@garnetsuss4881]

@@chemicalspore I'd remove the extensions and solder extensions if I were you. Less resistance(more accurate readings) and more reliable connections. Use 60/40 flux rosin core solder and not too much heat. Be sure to use shrink tube with "glue/sealant" so you ensure a water tight seal, thwn wrap it in loom. Your wcm will get more accurate readings that way. Not saying that the extensions won't do tue house b, but if you want your air/fuel mixture to be as accurate as possible, good clean solder joints are the way to go.

[@chemicalspore]

@@garnetsuss4881 i have had no problems. Thanks for your concern

[@SgtJoeSmith]

Go to junk yard and cut both plugs and few inches on each side and connect wires to make your own extension silly

@@AaronPowellvox what gauge wire?

[@AaronPowellvox]

@@chemicalspore depends on the vehicle

[@AaronPowellvox]

I wish I knew more about this stuff though honestly. I’m having trouble with mine and I’m pretty sure my wire is messed up somewhere but I can’t find the problem without removing the transmission. If I had a diagram I could just run new wires without going through all that trouble but resources are hard to find for some reason.
