Chandler Posted June 12, 2013 Share Posted June 12, 2013 right as the title says i need to find an o2 sensor eliminator or simulator, can anyone help? cheers Quote Link to comment Share on other sites More sharing options...
Didjeridave Posted June 13, 2013 Share Posted June 13, 2013 Is that to fix a CEL or are you trying to up performance? Quote Link to comment Share on other sites More sharing options...

Didjeridave Posted June 13, 2013 Share Posted June 13, 2013 Prob need a new sensor rather than an emulator. Everything I read about rhose things sounds like bad juju. Have you pulled the code? Quote Link to comment Share on other sites More sharing options...
Chandler Posted June 13, 2013 Author Share Posted June 13, 2013 ye and deleted it, but keeps coming up :/ Quote Link to comment Share on other sites More sharing options...
Didjeridave Posted June 15, 2013 Share Posted June 15, 2013 Deleteing a code doesn't solve the problem sadly! What code are you getting? If it's reading bad lambda, I'd replace that personally, seems many of the M's are of the age now where it's a common fault. Some sensor emulators just provide false readings to the ecu & you then might be wasting fuel by running rich without the ecu knowing it, or worse running lean & soon afterward melt pistons.

Chandler Posted June 16, 2013 Author Share Posted June 16, 2013 ye its definately running rich lol but surely cos im running a de cat a new sensor wouldn't eliminate the light? wouldn't i need a wide band sensor? Quote Link to comment Share on other sites More sharing options...
Didjeridave Posted June 17, 2013 Share Posted June 17, 2013 Wideband's only necessary for tuning. Also, your decat is downstream of the sensor, the cat normally reduces emissions gasses irrespective of the fuelling (the ecu does not 'know' the cat is normally present, so this is not factored in to the closed-loop fuelling system). For most of the throttle, the ecu puts the right amount of fuel in based upon the oxygen levels in the exhaust; the lower the voltage, the less O2 in the exhaust & thus the leaner the burn. Standard sensors don't make as much voltage as they should as they get old, making the ecu think the burn is leaner than it actually is & overfuelling, hence why mpg tends to deteriorate as the sensor wears out. Do you have the error code number? Quote Link to comment Share on other sites More sharing options...
