dunk Posted January 8, 2005 Share Posted January 8, 2005 me again with more problems:confused: well questions really... cars running fine now after the fuel problem... its a 90/91 2.2 legacy awd auto gx However... it doesnt seem to have an O2/lambda whatever sensor on the exhaust... do all the subarus have this? or are there a few early ones that dont use it... looked briefly at a wiring diagram for the ecu... has alook in the car also, there seems to be some white and black wires wrapped in a grey sheath that *might* be something to do with an O2 sensor but they are not connected to anything... there is no plug/nut/boss welded into the exhaust to take the sensor either.. i am a little confused as the car seems to run fine?!.. am i destroying the car by running it like this?... how do i go about putting the sensor in?..weld a nut onto the exhaust and extend the wires to suit?... does anyone have an accurate wiring diagram that i can check?.. any thoughts or suggestions would be appreciated..

Skip Posted January 8, 2005 Share Posted January 8, 2005 dunk Due to your location (across the pond from most of us) you have us at a bit of a disadvantage. Our cars do all have 02 sensors since around 1987. There were a few odd balls (87 4wd carbed models come to mind) But the Euro cars have been known to employ EGT (Exhaust Gas Temp) sensors in place of the 02 sensor. This no doubt due to the fact leaded gas was still available (lead kills 02 sensors). Best bet is to contact a dealer or forum in your area. The ECU does have a programed map to use when the 02 sensor fails, but the petrol mileage will suffer. Sorry I couldn't help. Quote Link to comment Share on other sites More sharing options...
dunk Posted January 9, 2005 Author Share Posted January 9, 2005 interesting! thanks for the reply skip... didnt think of it like that... still, if the egt sensor is supposed to be in the exhaust.. its not there now? hmmmn.. i know you can buy exhaust for the early legacies over here in "catalytic" and "non catalytic converter" style... will try and do some research... not going to be easy! this is probably the best forum for all round subaru tech stuff.. the ones over here concentrate on car with over 250hp... 90% of the time imprezza's... i dont own an exceedingly expensive imprezza and i dont want expensive mods... (hmmmn yet!..) i just want my car to go! thanks for the help though.. Quote Link to comment Share on other sites More sharing options...
