Zedrush Posted September 28, 2007 Posted September 28, 2007 Just drove back from a club at the Engine warning light came on had high flow cats zorst induction and plenum fitted but that was ages ago, apart from induction which was a week ago. Everything has been fine, but tonigth light came on hope its nothing serious I just slowed down got home switch engine oof and gone to bed, cant sleep as am worrying a bit is this serious, left my owners manual at work damn it Quote
Pingu2 Posted September 29, 2007 Posted September 29, 2007 guess you need to find what the fault code is.. theres a procedure for doing this if you dont have an obd-ii reader.. http://www.350z-tech.com/zwiki/ECU_Reset Quote
Kuro Posted September 29, 2007 Posted September 29, 2007 From what I remember of mine, a solid light is better than a flashing one. As has been said, you can read the codes yourself for peace of mind. From what I remember the procedure is tricky, but well worth it. It's more than lilkey some fairly minor, maybe a sensor problem somewhere. My 02 went pop after about 18 months Long shot, but if you've just filled up, sometimes not sealing the tank properly can set it off - apparently Quote
Emperor Ming Posted September 29, 2007 Posted September 29, 2007 If your oil level is al ittle low and you are 'driving spiritedly' it might cause one of the oil warning sensors to activate which under normal useage would not. Take a peek at the oil level later mate! Ming the Hopeful Quote
Zedrush Posted September 30, 2007 Author Posted September 30, 2007 My friend cam round yesterday and pluged his electronicy thingy into the ECU to find out what codes were coming up, it turned out to be my high flow cats lamber A and B were not reading correctly with the sensors as the sensors still thought my old cats were on, but because more stuff is coming out it got different readings and that sign came up. Did anyone else have that problem when they changed their cats? He took the light of now as well and said that it came on because of a certain cycle you have to do to get the sensors to react like that. He said he will book it in and find away where the sensors wont conflict with the high flow cats,so everything is back to normal now for now. Quote

I think with the high flow cats you need to get a MIL eliminator. This basically bypasses one of the sensors i think and tricks it into thinking that both are working ok. I had the same issue on my old MG. Maybe its the same thing with these? Quote

Get it into a dealer & see what codes it throws up or try the pedal procedure yourself. You could also buy an OBDII reader, comes in handy sometimes Quote
Tere Posted September 30, 2007 Posted September 30, 2007 Most likely a transient issue, unless one of the O2 sensors went bad (possible). If it keeps happening, have a garage check the O2 sensors. Neither high flow cats nor test pipes (no cats) will typically throw a code -- I've run both with no issues. Quote
Ian Posted September 30, 2007 Posted September 30, 2007 My test pipes kept throwing codes even with non foulers fitted. Once I cleared it down with my OBDII reader they have not returned in over 3k miles (they used to return within 50miles doing a reset with the pedals) Quote
Zedrush Posted October 1, 2007 Author Posted October 1, 2007 yeh he has cleared the sign off my dash, has not reappeared since touch wood Quote
