EcoFriendlyAL Posted November 23, 2019 Posted November 23, 2019 (edited) HI, I had EML on about a month ago but put it down to really rough road over Telford area. Used the OBD2 reader and cancelled the codes, think they were for sensors? Light hasn't come back on since. Forgotten numbers and lost piece of paper. Car failed on emissions yesterday, tester suggests a leak or crack in exhaust. Mechanic is looking at it Monday so should hopefully find if there is a leak. I believe sensors cost a hundred quid so will put off buying one just on chance. Any thought on most likely sensor that may be at fault if not a leak? Cheers AL P.S 350z 2004 about 60k miles Edited November 23, 2019 by EcoFriendlyAL forgot stuff Quote
ZMANALEX Posted November 23, 2019 Posted November 23, 2019 Probably a front sensor, however check the exhaust for leaks and also for a faulty cat. If you have sport cats on, then remember that the temps have to be very high to get through emissions. Genuine New Nissan sensors are in stock if required (avoid aftermarket) Alex. Quote
EcoFriendlyAL Posted November 23, 2019 Author Posted November 23, 2019 Hi Z Man, standard cats as far as I'm aware, it has passed the emissions the last 3 times. Thanks, I'll be ordering from you if it does turn out to be a sensor. Quote
EcoFriendlyAL Posted November 25, 2019 Author Posted November 25, 2019 I was wondering if anyone could shed light and maybe a cause from this info? Cheers Quote

Cheers Do you know what the code was for the EML? I had EML come up which was telling me it was the precat sensor, but turned out to be a very old, cracked and rusty exhaust gasket between the manifold and cats. Replaced them and EML went off. I would suggest checking the exhaust thoroughly for any leaks. Get it on a ramp, switch the car on ( have a cold exhaust so you dont burn yourself ) and feel around all the flanges where the exhaust pieces join. Also look around the cats to make sure they don't have cracks in it etc. Quote
EcoFriendlyAL Posted November 25, 2019 Author Posted November 25, 2019 hello Fijifixit, I deleted the codes and lost the peice of paper that they were written on. Just remember it being two codes, the same number but one with a P, i.e both left and right and think it said front sensor and possibly exhaust???? Mechanic will get it on the ramp today and have a good look. Thanks AL Quote

Both of our issues was regarding an exhaust leak that was throwing the sensor code. Hope it helps Quote
EcoFriendlyAL Posted November 25, 2019 Author Posted November 25, 2019 I talked to the mechanic and he found I had a broken exhaust bracket. He's put sealant on it and put a new bracket on it so hopefully that has sorted the emissions. My theory about very rough road was maybe correct. Quote
EcoFriendlyAL Posted November 28, 2019 Author Posted November 28, 2019 Glad to say it passed the emissions test today. Quote
