What to do if you are missing down stream O2 sensor

Does the 95 Honda Del sol have a Down Stream O2 Sensor? The guys at the auto parts store says it only has the one up front? IS there another one underneath? I can't find any video on that for the 95 Honda Del sol... Thanks!

[@tubejim101]

There should only be one. Honda did not switch to OBD2 until 1996. Two things that will help you. First, watch this video to tell which engine you have: kzbin.info/www/bejne/hXXVemSrppand6c Also, always feel free to call the Honda Parts department. Honda has the best parts department that I have ever worked with. If you go in, they will even print out parts breakdown pictures for you. They are very open about giving customers information about their cars. One last tip. Always give Honda a call and check their prices. Often their prices are better then the aftermarket. Good example is their oil filters. Hope this info helps you out. Have a great day!

I got the same car motor and headers and for me I got a code for the upstream not downstream so using that truck will it fix the code

[@nadeemkazi7917]

I have 2007 honda Crv , unfortunately it's wiring burned out , and couldn't get new one, I purchased from a junkyard full set of crv wiring BUT mine is having 2 o2 sensors whereas the wiring I got is having connections only for one o2 sensor. WHAT WILL HAPPEN IF I LEAVE THE OTHER O2 SENSOR AS IT IS WITHOUT CONNECTIONS??

[@tubejim101]

Sounds like you have a classic up stream, down stream o2 setup. You have to have the upstream so your engine will run correctly. The down stream is for emissions checking. So your ecu will have to guess how well the catalytic converter is doing it's job. It all depends on what Honda programed to ecu to do. If your lucky, it will just through a check engine light. If your not lucky, it may constantly be changing the amount of fuel is sprays, in an attempt to get the catalytic converter to work correctly. Some things to keep in mind. Try to use wires of the same length and gauge as the original wires. If the resistance is different, you will get wrong readings to your ecu.

[@nerfjackling9069]

so that means delect downstream o2 sensor is ok ? wont affect engine performance ? i not sure

Depends on the car, how the manufacturer set thing up.

You think this will pass an emissions test hooked up like that?

What I think does not matter for your emissions test. Every place is different.

tubejim101 never happened till o2 sensors replaced

[@tubejim101]

@@ItzJusAGameBruh84 Think if it was O2 related, you would get a check engine light. There are some holes in the bottom of you throttle. You can plug them with your finger, and it will tell you what is going on. I don't remember the procedure off the top of my head.

[@tacticalmosquitoeater]

Quick question, how can you tell the sensors apart? I took them off my cat a long time ago, I got it rigged up in a way that sort of works but It goes back into in closed loop, every time the engine is under 30 percent throttle or more.

[@tubejim101]

Upstream should be the shorter of the two.

[@tacticalmosquitoeater]

@@tubejim101 thanks! I’m assuming you are referring to the length of wire on the sensors. But since both plugs are in the same spot, and are identical, which sensor goes to which plug?

[@Nj888chu]

what do you do if you"re missing the up stream 02 sensor and the check engine light is on because of that ? (2000 civic ex)

[@tubejim101]

You have to fix it. That is how your car's computer knows how much gas the fuel injectors need to spray.

Ok I found it , I’m gonna replace it with a new one right now thx !

Is it okay to use the spark plugs and foulers in the upstream o2 sensor? I had to gut out the cat cause it was bad. We don't have emission test here but just trying to get the check engine light to go off.

[@tubejim101]

The upstream is used to run your engine. The downstream is used for emissions.

[@Turner2503]

@@tubejim101 Thanks, so I guess using it on the upstream is a no go then. I guess I'll just have to manage with the cel till I get a new cat then. 😔

Help I just bought a 1997 Honda Civic with engine d16y8 . That came with code P0141 code . I’ve checked my vehicle and I’m missing the bank 2 . Is capped on the exhaust and I don’t see a connector anywhere . Any help to correct this issue ?

[@tubejim101]

Think you mean bank 1 sensor 2. The EX should have the wires going out the bottom, near the shift boot. The ecu is looking for the heater on sensor 2, which it sounds like your missing.

[@blu3cha0s]

Did you ever figure it out? I can't find the harness plug near the shift boot. Or next to the upstream area. Any help?

Soooo u rigged ur downstream o2 so that the ECU thinks it's all gravy???

[@tubejim101]

I think what happens, is if the up stream and down stream oxygen sensors are reading to close to the same numbers, you get a check engine light. If the down stream is getting a different reading then the up stream, then the computer thinks the cat is doing it's job, and you get no check light.

[@ronbridges678]

I know nothing about Hondas but my Z/28 the downstream sensor tests the performance of the catalytic converter. It helps the computer control the fuel injection. My car runs like crap without it.
