No more c.e.l

No more "Check Engine Light" for me. Finally got my Urd rear o2 sensor simulator today and just put er in. Took about 5 mins. Theyve changed it from having to splice the simulator in to a simple plug and play.



First thing to do is unhook the battery.
Then your going to have to get underneath the carpet under the passenger seat. So unscrew the 4 screws holding the plastic down and lift the carpet up,you will then see the wires goin to the connector that your goin to need to get to.



Then reach in under the carpet and haul out the connector.



Separate the male end from the female end of the connector and connect each of them to there proper connectors on the simulator. Tuck everything back under the carpet,put the plastic back on and hook the battery back up. Thats it. No more "Check Engine Light"

 

definitely doing this soon....then getting rid of the cat. converter.

 

Where did you get you rear o2 simulator? I have the similar problem. Thanks

 

Thanks for the write-up and pics. Made it really easy to know exactly where the connection under the seat was.

Curious, why not just fix the actual problem?

 

Just ordered a simulator today and was wondering where it hooked up. I seen the wires went through the floor so I was hoping it was right there. Good job on the write up!

 

Cause it's expensive Bama! All mine is is a bat cat, but the dealer wants upwards of $900 for a new one. Im about to do this, but I think my 1999 is under the truck. I found a thread stating it was and URD says the box is completely waterproof, so it's not a problem under the truck

 

I didn’t pass my inspection so I just bought this. I basically all points of the catalytic converters. I’m going to install it tomorrow and go back to an inspection place. I’ll update how it goes.

 

Thought I’d share this here

Yep, that’s what I ended up doing. It cleared my CEL.

 

I removed one of my cats during the trd header install, didn't get a CEL but Im using fic6 to tune for my 3.4 supercharger and wanted to make sure the O2 readings are not messing with my tune.
That's reason for getting this simulator. It sure would be nice if URD had better description of the install instead of shipping the part with just a sticker. Oh well..

 

I had to call them and look it up on YT. Once I knew how to it was a cinch.

 

I bought a Tacoma that had a URD O2 simulator on it pre installed for running no cats and it went bad after a few years of driving around Detroit area. I’m thinking it’s a good idea to only leave it on when you need to pass emissions so you can keep it in your house away from the elements, rather than have to buy a new one every few years.
