check wit's end as I think he has them from the OEM manufacturer
^^this first
Or...I have these part numbers I was planning to get for my '93.
O2 sensors/flange nuts- Denso -
234-4157 - Upstream - $55
234-4153 - Downstream - $50
90179-08059 / 90179-08101 - flange nuts
Forgive me if I misremember the outcome of the great discussion over Denso or NTK specifically for ODB1. I got these part numbers going by overall positive forum consensus. But there was so much, I may have it wrong even still.
Blyme!Above are OBD2. Not for the 93.
As far as I know NTK was the original supplier fir Toyota for our OBDI trucks.Was going to order from him. Wit's End does not have them in stock. He carries the NTK.
234-4157 - Upstream - $55
234-4153 - Downstream - $50

I just ordered and received one from Toyota for a 94. No issue.
See post above. I forgot to reply for you.@matzell -- which dealer did you order from? I'm having trouble finding OEM sensors. I've been about an hour digging on Mud and most research on OBD1 sensors is mixed, saying either the NTK or Denso ones are either for OBD2/95-97 and won't fit, or if they do, they will crap out. I've found some from Partsouq on eBay but looks like it doesn't come with the gasket or nuts like the OEM kits. Does anyone know where to source those? Thanks.

Get you O2 sensors here. NTK are the ones for that version.
And it's 93-94 are OBD1
95-97 are OBD2
If you want to confirm availability, check these two places.Was initially going to buy the obd1 NTK O2 sensors from Wits End, but they are OOS. The NTK part# 24044 (long harness bank1 ?) is not available anywhere. You can still get NTK part# 24080 (short harness bank2 ?) from other vendors.
Still trying to find out which OEM part# is available, but no solid answer. Also trying to find out which part# has the longer harness. At least if the one with the longer harness is the only one available, you can use it in both banks.
I ended up buying DENSO 234-4520 x2 for the meantime until I can confirm the OEM part#s.
Thanks --See post above. I forgot to reply for you.
Thanks both -- yes looking for OBD1 for my '94. Wits sold out of his NTKs. I've asked if he is restocking. Toyota # is 89465-60110, which is for a kit that has both, not sure if that was what you're looking for @migz808. Haven't had any luck searching for dealers that have them. Interested to see how the Densos do if you do in fact install. Not sure what the other option is if Wits doesn't have them and the dwindling or non-existent supply of OEM ones from Toyota, which seems to be the case.Was initially going to buy the obd1 NTK O2 sensors from Wits End, but they are OOS.

Thanks -- I believe these are for 95-97/OBD2 trucks. OBD1 trucks require different ones (#89465-60110) I think.
