Mkiv jdm Posted November 13, 2019 Author Share Posted November 13, 2019 Only thing I can think is possible the reading is non existent . It says main fault is lower reading than 0.4 . My car isn’t Idling great + fuel consumption is lower than 15mpg. Car also smells very rich . Meter is coming up 0 . and with different pins it’s reading v Link to comment Share on other sites More sharing options...
mellonman Posted November 15, 2019 Share Posted November 15, 2019 If your reading it correctly then maybe the sensor has completely failed if giving no reading at all Link to comment Share on other sites More sharing options...
Mkiv jdm Posted November 17, 2019 Author Share Posted November 17, 2019 I’m gonna try and take them out . Do the two nuts at each side of the sensor in the manifold need to come out or can you screw sensor out . With the heat I would say there probably welded on.

Chris Wilson Posted December 3, 2019 Share Posted December 3, 2019 You need to undo the two 12mm hex nuts on the studs to remove the sensor. You really need a scope to make sense of the O2 sensors or on a VVTi a scan tool that will read the early OBD2 data. I use a Carman Scan, not many will read them. To be honest once you wrestled the thing off you might as well just renew it. Forget all the soak in vinegar crap... Link to comment Share on other sites More sharing options...
