Changed the sensor on my 2011 4.4 for fault P040D-00 (2F) Exhaust gas recirculation temperature sensor A, using the excellent guide / knowledge on here and spotted this down the side of my battery, it didn’t appear to have any use there, any idea where it should be fitted??

If you clean it up you may see a part number, then google is your friend Pete
