20v blacktop oxygen sensor

[twotoedbandit]

Been looking for a replacement o2 sensor for my blacktop. Can't seem to find a definitive answer on an available replacement. Is there a confirmed to work denso 4wire replacement I can easily order? Part no if possible for the replacement or a link. Thanks!

I don't have the part number on hand, I'll see if I still have the box when I get home. However I used a 4 wire Bosch o2 sensor from autozone and plugged right into the harness and never had a check engine light.

not 100% sure but i think u can use the 3sgte from a mr2 turbo on the blacktop

[twotoedbandit]

Thanks guys, I'm sure one of the universal denso or Bosch sensors will work, just wanted a confirmation from someone who has used one. The oem number doesn't give me any cross reference for cars when I google it. Xb, if you do have the box for reference that would be awesome! Any other ideas guys.

I think I may have cross referenced it to a turbo mr2. I'm pretty sure any 4 wire o2 sensor that will plug in will work. I believe almost all of the 4 wire heated narrowband o2 sensors work the same!

I saw in another post by hasport that you can use one from a 3sge sw20 mr2. you will have to splice the plug from your 20v o2 sensor to the mr2 sensor for it to work

if you go to oreily auto parts they sell a universal oxygen sensor that doesnt have the plug. if you cut the connector from your 20v o2 sensor and splice it to this one you will have a o2 sensor here is the link about 50 bux or so

Awesome! Thanks guys, exactly what I was looking for!

Buy an OBX 3sgte o2sensor for $60 on eBay. Go to the junk yard and snip the 4wire plugs(you need both ends) from any mid 90's Camry or other Toyota. Re-pin exactly as they are. Plug, play...

Bosch worked for me for a year then just died without warning. Maybe it was overwhelmed by the 20v's.

Does anyobdy know of if the stock 7AFE oxygen sensor will also suit the 4AGE Blacktop?

Part number is 89465‑20520.

[morgan]

if its a 4-wire, it should.

[onnaj]

I think mine is 2-wired, but have to check that. I don;t have a OBD2 engine and only one oxygen sensor, so i think it's 2-wired. I think the OBD2 equipped angine had the 4-wire sensors already.

20v needs 4 wire

[greenae102]

20v bt uses the same O2 as 8th gen corolla (98-02) and 94-95 4 runner with v6. I have the bosch sensor on my car now p/n 13051. Plugs and bolts up perfectly.

I've ordered this one:

http://www.ebay.com/itm/150826551109 (Bosch 15728 4-wire universal) For that price it couldn't hestitate to buy

[greenae102]

hell with that wiring

[onnaj]

hell with that wiring

no problem, still have to adapt the 4AGE harness to the 7AFE harness, so this is just a little bit extra

[morgan]

Thing I don't like about them is 2 wires are same color. None of which match the harness. Good luck if its not assembled and/or labeled

[greenae102]

I work at oreilly and guess what ...they're not labeled lol. No telling why tho

[onnaj]

Sorry but they are lables and there's a table to compare the wires with the OEM wires. Made a picture of it!

Then you check here: http://www.padandwheels.com/mr2/blacktopproject/engharness/engharness.html. Then you check over here what colours should be matched. I think i can say this really is doable.

After all i have a 4-wired oxygen sensor already on my 7AFE. One of the difference with the US spec models i think. Never knew there where OBD-1 equipped 7AFE's that had 4-wired oxygen sensors.

Even my exhaust header is exactly the same size as the 20V one. Only the connection to the head is a bit different.
