Mazda 6 - ODB Readings - emissions fail
Hi all. Have a 2008 mazda 6 that failed on emissions. Readings were miles off
Low Idle (700 rpm) CO 5.96 Vol% HC 271 ppm High Idle (3000 rpm) Lambda 0.81 CO 7.17 vol% HC 350 ppm Mechanic says it COULD just need a new oxygen sensor but for the age of the car and needing new brake pads he was leaning towards me scrapping the car but I love the car and hate to see waste. So wondering if anyone on here would be able to look at these odb readings and tell me if they think oxygen sensor should do the trick and then a bit of cataclean after might get me past the nct. First MAF with two revs seems normal https://imgur.com/BK7PCMi Worried about the cat fail on that but not sure could that be sensor 2? https://imgur.com/KmAlkAu This is with a warmed up engine and multiple 3000 revs and nothing changes. I think its meant to be close to zero mA on sensor 1? and moving back to zero but this just stays at 6.35mA https://imgur.com/AHTA9Rq Here is a list of all the readings at idle https://imgur.com/hF6Mn6t Then a list of all readings at 2000 RPM https://imgur.com/ZLfqArO If you need any more readings or info just ask and I'll post them Thank you in advance to anyone willing to give their time to reply. |
