Complaint<\/strong><\/p>\n

Check Engine Light ON, for Injector 5 and 7 Circuit Fault. Runs fine<\/p>\n

Cause<\/strong><\/p>\n

Truck only has 5000 miles on it. Ford has replaced 4 injectors and the PCM already at 2500 miles. CYL 5 injector is original yet but 7 they replaced. When the Truck is cold all injectors show the same resistance reading. Once the truck is warmed up 5 and 7 resistance goes high. others all stay the same. I tested at the PCM and directly at the injector and got the same high reading. Truck runs perfect even after it sets those codes.<\/p>\n

Correction<\/strong><\/p>\n

Replaced two new injectors in and problem was solved.<\/p>\n
