Alex Posted September 29, 2005 Share Posted September 29, 2005 The one behind the car is probably a temperature sensor...take the other 2 out...if they look the same they probably are the same....I've not seen an NA exhaust to 100% confirm from the comfort of my desk.

Digsy Posted September 30, 2005 Share Posted September 30, 2005 Sounds like you've cut the temperature sensor by mistake. Link to comment Share on other sites More sharing options...
Gazzawu Posted September 30, 2005 Author Share Posted September 30, 2005 ok problem solved if any of u guys cant afford to buy two o2 sensors from toyota cos ur a poor student like me then just buy the bosch universal type. cos mines is a single wired type u will have to get the single wired type.....doh! the bosch part number is 0258 986 501 only £35 each. so just remove the old ones with a 12mm wrench and splice the new ones onto the wire leading to the harness. let the car idle for 20 mins and thats u. by the way u will need an adapter plate to fit them in cos the toyota ones are welded in theyre like a £5 from thor.

SatSport Posted September 30, 2005 Share Posted September 30, 2005 Hmmm, so why do they need 2 o2 sensors anyway?? Link to comment Share on other sites More sharing options...
