Steve Posted March 11, 2013 Share Posted March 11, 2013 Hi and welcome try this guide from our UK Lexus Owners Club it has a diagram http://www.lexusownersclub.co.uk/forum/index.php?app=tutorials&article=174 Note that the part should have a color coded tag on the cable and therefor should match the color when replacing part Also note the car on the picture is right hand drive, so any references to drivers side should be reversed for left hand drive.

mgbarker54 Posted June 12, 2013 Share Posted June 12, 2013 Be careful to take your part out and compare it to the reported new part. There are several oxygen sensors even if you narrow-down which one you need on your car. Best of luck. Quote Link to comment Share on other sites More sharing options...
