Dambuster Posted February 22, 2007 Share Posted February 22, 2007 Help, my FI warning light is on, I have managed to find its fault code 23 Can anyone tell me where the O2 sensor heating element is and what I need to do to fix this. Thanks Mike Quote Link to comment Share on other sites More sharing options...
JohnS Posted February 22, 2007 Share Posted February 22, 2007 The heating element is a part of the O2 sensor located behind the collector box in the exhaust. Use a digital multimeter to check the voltage on the white wires (I think) but check which is which by searching on google on 4 wire O2 sensor. If you have 12v across the heater wires then replace the sensor. If you have no power to the sensor then it will be an ECU or wiring problem (you do not want this).

Dambuster Posted February 23, 2007 Author Share Posted February 23, 2007 Thanks for the info, sounds like its a job for the garage. Mike Quote Link to comment Share on other sites More sharing options...
Iceman_40 Posted February 24, 2007 Share Posted February 24, 2007 Thanks for the info, sounds like its a job for the garage. Mike Honestly first I'd check/clean the connectors. It's easy and you'll likely do a better job than the shop. Quote Link to comment Share on other sites More sharing options...
Dambuster Posted March 18, 2007 Author Share Posted March 18, 2007 Cleaned all conections, its still on even after a reset. Took it to the garage and asked them to service it, oh heck its the 16000. So far the bill is coming to £600, that does include a new o2 sensor It should be ready by Tuesday, who cares at the moment we have snow. Take care out there guys and gals Quote Link to comment Share on other sites More sharing options...
