i got this tahoe in today and they were complaining about the check engine light being on, i check the codes and there were 2 for o2 sensors, so after i check out all the wiring and determine that it was faulty sensors i replaced them but i noticed that they were taped up so i took it off and this is what i found..........


what the fudge were they trying to do, i can only guess thats its a poor mans version of a o2 simulator or something of that nature, but it only ended up destroying the sensors and costing them $500,

 

WTF?

 

thats the poor mans mod for getting more power by adding more fuel, it is supposed to fool the O2

 

adding more fuel to a tahoe wow, i try to figure out ways to use less fuel and i drive an xB! lol.

 

didnt fool anyone, and all it did was cost them money

 

Actually depending upon how it was connected it may have been leaning out the A/F mixture giving them better gas mileage but too lean would cause O2 sensor failure or overheating or both. It would depend upon the resistor values used and what the O2 sensor had for resistance normally.

 

you can get away bein a little ghetto with some electrical, but this takes that **** to a whole new level...

 

well the way they had it wired it made the sensors stuck at 447-451 mv, then the ecm see's that its not switching and sets the codes and the checkengine light, which in our area causes you to fail your emissions inspection, but there is a upside, it puts more money in my pockets, hahaha, but then it is quickly gone again.....usually another mod for me

 

that's funny...who thinks of this stuff....I'm sure someone making more money than me

 

haha!

 

lmao

 

It would have been cheaper in the long run buying a power programmer and doing it right. Da, Da DUH!!!

 

ahahha

 

you would be suprised at all the ghetto mods i see on a daily basis here

 

coming from a mini trucker background i have seen things that would make you cringe, but hey ghetto works if its done right...that doesnt look like it was done right, that looks like crap...
