Had a good look through the forums but haven't seen the answer. Where exactly is the O2 sensor/lambda and how can I clean it? (CE light on intermitently and think it's the cause)
OK, how about this for the perfect thread at this point :cheesy: :Dhanda said:if your sensor has 3 wires one is for the sensor, the other two are 12v live and earth, these are for the heater element which heats the o2 sensor to operating temp. my culprit was the earth and ended up cleaning the earth points on the top front of the cylinder head as thats were it ends up and light has never come on again. By the way i think the live is no 1 fuse.
