SES Light Code P1131
So i bought a 2000 F150 4X4 Lariat back in June and just had a new motor put into the truck. Now i am having the service engine soon light come on and my little scanner reads code P1131. I have replaced all the O2 Sensors with Motorcraft Sensors except for the front passenger O2 sensor...Hopefully by changing the front passenger side O2 sensor maybe it will fix my issue..But just checking to see if anyone else has had this code appear and it be something else.
