I’m getting repeated P1143 on my 2002 Nissan Xterra. I usually get some odd code every year when it gets cold…then goes away when the weather warms up, so thought that here,…but we’re now into 40’s and 50’s in Maryland and P1143 is back. Any more experience from anybody on Xterra’s, old ones (my baby! 🙂
