The thread I never thought I'd start...

Oops, didn't realize they were dual purpose.

Yes...1) keychains and 2) xmas ornaments. No other usage whatsoever. Certainly nothing outside the design's intended use.

I was getting an intermittent 02 CEL on my '93. It started with coinciding with heavy rain (so rarely, in NorCal) but then got more frequent. I tried greasing the connectors, swapping the connectors side-to-side to check for electrical vs sensor problems, cleaning the sensors themselves, and finally swapping them around. Ultimately I replaced the bad sensor with a spare I had laying around.

Good luck.

As far as the records from Toyota say the PO changed the O2 sensors in 1997 under the recall. No record of changing since. But he didn't do all of the service at the dealer so no idea. Going to take it to my muffler guy tomorrow and have him check things out. He's cool and honest. He charged me $35 to swap out the sensors on my 92 and backflow check the cat.

Check your O2 connectors for moisture and corrosion. I've had that code come up when driving through deep puddles. I just unplugged the two connectors, dried them, and applied dielectric grease.

Yes. I knew it was the O2 sensors. That's what I mentioned in an earlier comment on this thread. I just was aggravated and tired. I've deleted my PAIR system so I'm thinking I will relocate the sensors there. Have to look up how to do that.

I have a sneaking suspicion that I messed them (or the wiring) up when I was going through the mud this past week. It was deep, thick sh!t.

250 miles today. Mix of "city" and "highway". No code. I was going to take it to my muffler shop today but delayed it to tomorrow. Taking the day off work so it will be easier. I don't feel like dealing with it.

 

[LS1FJ40]

This is the connector on the fender side. The one that gets pounded with mud and moisture. A little bit of corrosion.

 

[LS1FJ40]

It's amazing what a little corrosion on a plug can do. Loping/rough idle is gone. Idle pegged at 650. Smooth. Truck runs smoother. Crazy.

I tried waterproofing the with silicon "tape", but moisture still got in. I'm going to see if a large diameter tube of heat shrink would do the trick. Need some ideas...

Clean the connectors with WD40 and compressed air until they are all shiny and spotless. I use Amsoil spray grease for any connector exposed to the elements. Works extremely well.

...Contact cleaner

That is how they cleaned them. WD40 and air. But they used dielectric silicone grease.

I'm going to move them to the PAIR location. Just need to figure out what plates I need... paging @NLXTACY

I'm assuming you mean which keychain/xmas ornament would best represent something that *might* fit even though it would go solidly against the original intent of the design...that of course being a keychain.

You guys that have the freedom to relocate O2 sensors and delete emissions components piss me off because I'm subject to Kalifornia's stupidity!

Correct! The keychains!

We also have low taxes, big deer, and 25 round magazines!

We have 3/4 of the countries national parks and 7/8 of the countries America haters. Oh yeah, and we have noticeable elevation change.

We have water.

And your national parks are going to be sold/leased to the highest bidder for oil/natural gas. Here's to the new regime!

I'm thinking we have more água than all of Iowa's water towers combined at this point. We need more reservoirs to contain the snow melt that's forthcoming.

Yeah, but it won't rain for another 10-12 months...

Don't try to "seal" the connection - it is near impossible to seal a connector effectively, and any attempt will only hold in more moisture than it keeps out.

The contact cleaner>WD-40>compressed air>dielectric grease is the ticket. Cheap, relatively easy, and very effective.
