I was jus watchn 2 guy garage and the showed this thing that plugs between teh O2 sensor and harness it keeps the check engine light from coming on and stilllets teh puter get the info it needs. problemm is I cant remember what they called it or who makes it.... Guess this is pointless now huh.....

 

MIL eliminator. They work very well on cars running off-road (ie no cats) exhaust with OBD2. Never once got a check engine light in any car I put em on.

 

where can i get mine?

 

you could use a resistor. all you would have to do is find out the voltage a "correct" rear O2 would read and put a resistor in the wiring for the rear o2. Basically at that point you would just fool the ECU into thinking the cats are doing the job they have to, and the CEL wont come on... Im sure there is an easy way to use a resistor of some sort, and find the voltage range a rear o2 needs to be at to prevent CEL's

 

uhh fuck all that resistor shit, and MIL elimintors are to find, summitt racing or even your local go fast store will have em. mine where $30 for both. also i dunno abut imports but my car actually ran better after the eliminators cause the computer was thinking right in stead of trying to adjust for not having cats.(catalatic converters) but those work very well if your check engine lite is one and thats the problem for sure.

 

wrong forum......

hmm. i might need to get one of those. my obd2 sensor apparently doesnt like my high-flow cat very much, cause it lately always throws the check engine light for it.

 

have you tried resetting the ecu?
