Fault code help please - Landmark - 12-12-2011 Hi Folks, The engine management light keeps coming on on our 2002 MkI 1.4 Multispace. I have read the OBD and it always shows "Generic code P0130 O2 sensor curcuit Bank 1 Sensor 1". I assume from this it's the first sensor in the system i.e. the one at the top of the engine at the front by the exhaust manifold. If this is correct it was only replaced in June (along with the cat). I have cleared the fault code twice so it's not an old one. Any suggestions please. Regards, Griff RE: Fault code help please - Ol'Jeffers - 12-12-2011 Maybe try checking the connectors on the sensor, if that is in fact the one that the code refers to. Not much help I know...cratch: Oooh! Just found this! http://www.obd-codes.com/p0130 may be some clues here too.... http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P0130/Diagnostics/Citroen/Default.aspx RE: Fault code help please - tucker - 12-12-2011 1 is on the manifold, 2 is on the cat. If it was only replaced in June, I'd take it back as it will still be under warranty. I'd check it's nothing obvious first though. Make sure it's fitted to the connector properly etc... RE: Fault code help please - Landmark - 13-12-2011 Thanks for the prompt reply. Will check points mentioned (& on web site) and report back. Cheers Griff RE: Fault code help please - wertyu2007 - 13-12-2011 maybe you have a problem ? fully serviced ? below for obdcodes.com P0130 is a bad oxygen sensor, however this isn't always the case. If your o2 sensors haven't been replaced and they are old, it's a good bet that the sensor is the problem. But, It could be caused by any of the following: Water or corrosion in the connector Loose terminals in the connector Wiring burnt on exhaust components Open or short in the wiring due to rubbing on engine components Holes in exhaust allowing unmetered oxygen into exhaust system Unmetered vacuum leak at the engine Bad o2 sensor Bad PCM RE: Fault code help please - Landmark - 13-12-2011 Hi wertyu2007, New top sensor & cat in June 2011 New plugs, crank sensor, air & fuel filter in Jan 2011. New ingition coil April 2010 All connections/wiring and fuse seem ok. Just tying to work out how to check voltages as on web link. Also need to check exhaust manifold has no leaks. I assume it's safe to keep using the vehicle? Regards, Griff RE: Fault code help please - pk7478 - 13-12-2011 Hi Landmark. Who is manufaturer and what model of Lambda-Sond which installed in your car now? RE: Fault code help please - tommyberlingo - 13-12-2011 they are very sensitive the tips of the lambda sensors, maybes the mechanic had dirty hands and put oil on it, and its burnt on when he installed it? best thing to do is check the resistance, the feed and the voltage given off it with a multimeter before replacing other parts etc. RE: Fault code help please - Landmark - 14-12-2011 (13-12-2011, 11:10 PM)tommyberlingo Wrote: they are very sensitive the tips of the lambda sensors, maybes the mechanic had dirty hands and put oil on it, and its burnt on when he installed it? best thing to do is check the resistance, the feed and the voltage given off it with a multimeter before replacing other parts etc. Haynes manual dosen't show wiring diagram for sensor curcuit. 4 wires come out of sensor 2x white/1x grey/1x black. Both white and grey go to green wires in loom/ black goes to a brown. I know 2 are for heater (12 volt feed and presumably earth) and 2 for sensor info (5 volt + earth?) but which are they so I can check voltage. Regards, Griff RE: Fault code help please - wertyu2007 - 14-12-2011 is it safe to drive if its running rich it could / would damage cat . |
