o2 sensor by-pass

reaper of souls · Post by **reaper of souls** » June 19th, 2006, 3:42 pm

ok i don't know if it's possiable but is there a way to by-pass the o2 sensor and trick the ecu to seeing the proper voltage./

i belive that my o2 sensor is going but i don't have the cash to replace it (in canada it's at cheapest $85 plus tax)

now other option if i pull it out is it possiable to clean it and still have it work ???

sorry about all the questions but i'm used to working on carburated engines i hate all this obd crap

Bypassing the O2 sensor is not good for the engine (or the mileage)- The ECU is constantly making adjustments based on the O2 values. There is no way to "guess" the O2 values - if there was a way then mazda engineers would have chucked the O2 sensors long time ago.

Cleaning the sensor might be possible - but will greatly compromise the sensing element - which is probably already shot.

You can get generic O2 sensors for something like $15 - only catch is it will require some wire cutting and splicing.

up here in the north they want at least $85 for the generic o2 sensors (and thats with a mechanics discount ) i have no idea why they are so expensive up here.
if i were to clean it what would be the best way to a) get it cleaner than it is now and b) not compermise the sensor too much ???

maybe cheaper than cleaning -
