Good evening, i'm Italian Boy and my English is very poor, sorry.

It's possible bypassing or simulating an O2 sensor ?

P.S. In Italy the Thecnique of American Cars isn't know and the person they are useful.

Yes you can use an o2 simulator. If you bypass it the check engine light will come on.

I'm sure someone makes them for your engine. I cleared the guts out of the catalytic converter on an '02 Firebird once, after which the downstream O2 sensor started throwing a code. I installed an O2 sensor and it cleared the check engine light. Very handy.

Why do you want to bypass the o2?

Because i have a gpl system and they generated error at 2O sensor.

In Italy the fuel price is 1,6 € Liter and the american truck mounting a gpl system

I am looking for some o2 sensor simulators or eliminators myself. I put headers on and a custom side exit exhaust. The headers had a place for the front sensors but there is no place for the rears and I don't want to attempt drilling in my custom exhaust possibly destroying it or causing a leak. I can not find them on internet searches for a Silverado/GM/Chevrolet. I have a 2002 model and right now the rear sensors are unplugged from the harness mounted on the frame and stored in my toolbox.

Anybody have any solutions for what I want to purchase?

With a custom tune you can turn the rear O2 sensors off

I have tried most or a lot of the websites that pop up under search terms but have not found any simple good results that will fit or claim to fit a Silverado. Maybe I can't get what I am looking for but have found many online posts refering to "dummy o2 sensors", "o2 sensor sims", "o2 sensor simulators", etc.

I was hoping someone had found a solution already that was in use currently.
