Thread: HOW: Most OBD II: Remove the Rear O2 Sensor

well im racing the clock here to get inspected, in ny its a plugin test. any codes you fail, and you have to have all sensors ready , but your aloud to have 2 not ready. i have 3 not ready, o2 sensor, cataylst , and egr according to my cheapo code reader. but im throwing no codes. wtf i say lol

EGR is an easy fix, install back all the sensors but leave them dangling around hehe.

actually ive done that, and no thrown codes lol no ready yet though. the fix i posted above actually works. i got it to ready up. but then i threw a knock sensor code so i gotta erase and redrive again ugh odbII

So, you used the same delete with both the three-wire and four-wire sensor and it worked with both? I am currently on my stock 98 ecu and I am going to delete the rear O2 soon. Eventually, I will be switching to a 95-97 ecu and I am wondering if I can use the same delete device.

The 4 wire delete worked on my 99 ECU, and when I installed the 96 ECU it kept on working. Granted I had Calum delete the EGR and Rear O2 but the code still popped up so I reconnected it, has been fine so far, just gets freaking hot .

Which is why need to find some other resistors that will hold up better.

Any update on heat resistant resistors? Lol

Good to know. Thanks for the info.

Updated the first post with a new method that seems to be working just fine.

Old setup didn't do too well:



New setup:

Bump, get rid of my O2 sensor light!

Fix it.
