supRo Posted December 19, 2005 Share Posted December 19, 2005 Hi, My mate has a UK car, I believe one of the o2 sensor is the same position as a pre-vvti jap tt - on the down pipe? Whereabouts is the other o2 sensor and how do you replace it, I think it's in the nearest cat? Toyota have told him that if thats to be replaced, the wiring goes under the passenger seat so the passenger seat will have to come out??!! His MOT failed on the Lambda readings. Thanks, Ro Link to comment Share on other sites More sharing options...
Gazzawu Posted December 19, 2005 Share Posted December 19, 2005 there are 2 o2 sensors on the downpipe that can be accessed from the engine bay. think there is also one after the 2nd cat and i think its a temp sensor. Link to comment Share on other sites More sharing options...

Thanks, Ro Hi Ro The wireing goes under the driver seat.The socket is located under the mid consol in front of the handbrake(under the carpet).You have to get a arm under the carpet to pull the sensor into the car(best way is from the door/sill side).It's a PITA to be honest,but you'll just have to feel your way under there.

absz Posted December 19, 2005 Share Posted December 19, 2005 Hi, His MOT failed on the Lambda readings. how bad did it fail on emissions ? if the co level was within limits and the lamda was just above it could just be a small exhaust leaks (joints) or the engine needs to be hotter.

absz Posted December 19, 2005 Share Posted December 19, 2005 also if your mate is buying a new sensor try LSUK in sedgwick rd will be the same part but half the price:D Link to comment Share on other sites More sharing options...

Yup, the co was ok - the Lambda just above! also if your mate is buying a new sensor try LSUK in sedgwick rd will be the same part but half the price:D Thanks!
