Hey guys i was wondering how to delete (trick) the o2 sensor. I have a 1997 240sx and I wanted to delete the second o2 sensor (after cat). Any info on this would be great.... I've seen o2 deletes on ebay, but I'm just a lil iffy about those. Any help would be great!

O2 sensor delete?
Re: (180fan)
any more info? what type of resistor ect? i know on dsm's when you eliminate it you put a resistor in and some other stuff.. but it puts off a lot of heat and has caused some issue's before..
so please more specific
so please more specific
I Just put in a DC sports racing header and had to replace the 02 sensors. I'm having the same problem with the second sensor. Because the bung they put in the header is not the same as stock I have to come up with some sort of hybrid 02, and I'd rather just eliminate it. If someone has dealt with this before some help would be greatly appriciated.

Well I'm happy I'm not the only one who wants to delete an O2 sensor. I figured a resistor would be needed, but wut ohm (ibeleive thats the correct word) is needed? Any help or experience would be great!
Re: (mr2lickit)
Just out of curiousity, why would you want to remove it? Trying to keep it from entering closed loop?

Re: (2FAS2C)
I had the same problem, except I didn't get the DC header. I have a Greddy (goes down to the downpipe only) header with a Megan downpipe (header to second cat, with flex section) to eliminate the first cat and to eliminate the chance of the Greddy header from cracking.2FAS2C wrote:I Just put in a DC sports racing header and had to replace the 02 sensors.

On the Megan downpipe, I had the same problem with the bung not matching the 02 sensor. So I went to a hardware store, bought a nut that the 02 sensor can fit into, then took them to an exhaust shop to have them weld that nut onto the bung of the Megan downpipe. That's how I fitted the second 02 sensor on.
So what's the benefit of "deleting" the second 02 sensor? I know that my first 02 sensor (the one that goes into the header) was in bad shape. It made my car run like crap. After I had it replaced, it made a world of a difference. I'm not too knowledgable with this.

Re: O2 sensor delete? (mr2lickit)
Did anyone find out on how tod do this? What's the ohm and how do you apply it? I need this info bad because my test only smog is due and my light is on. The car sniffs clean tho. Plus, I just found out that the cat for the car $450. Thanks in advance for any help![email protected]

This from the '95 FSM but it should be relevant.

Put a test pipe in my girls civic, I attached one of these simulators to the secondary sensor, havent had a cel in 500 miles or so.
