mc Posted June 21, 2013 Share Posted June 21, 2013 I gather this means I'm running lean, could this be caused by an air leak? I am thinking exhaust most likely? Quote Link to comment Share on other sites More sharing options...
Sly@Kaizer Motor Posted June 22, 2013 Share Posted June 22, 2013 If you have both in the same time, than it's more likely to be one of the last 3 of these (official causes for this fault code): Air fuel ratio (A/F) sensor 1 Air fuel ratio (A/F) sensor 1 heater Fuel pressure Fuel injector Intake air leaks So yes, probably air leak (or low fuel pressure, but check for air-leaks first).

mc Posted June 22, 2013 Author Share Posted June 22, 2013 Thanks for the info. I have cleared the codes for now, will see if it comes back and then check for intake leaks (after the airflow sensor I presume, guess I am looking for split hoses etc?)

Sly@Kaizer Motor Posted June 22, 2013 Share Posted June 22, 2013 (edited) No problem. Yes check your system after the air flow sensor, search for split hoses or a gasket leak ( any unusual hissing noise).

mc Posted June 24, 2013 Author Share Posted June 24, 2013 Well the codes come back every second trip or so. It now sounds like I have an exhaust leak which is getting slowly worse. Trying to stick my head under the car it appears to be forward of the y-pipe, but difficult to tell with the undertray in place. Could this be the problem or just coincidence?

Sly@Kaizer Motor Posted June 24, 2013 Share Posted June 24, 2013 If you have an exhaust leak, than it's can confuse the O2 (A/F) sensor, so yes get that sorted first. Quote Link to comment Share on other sites More sharing options...

mc Posted July 5, 2013 Author Share Posted July 5, 2013 (edited) Got the exhaust leak fixed, replaced the triangular gaskets between manifold and cats. Engine check light came back on this morning after staying off for a day. just 1283 this time so I'm hoping the ecu is relearning after running rich for a while...
