P1316 code issue

[7.3Powerstroke20]

I have had the p1316 code for quite some time now but have had no symptoms at all the truck runs great. I finally decided to figure it out and took it in for a buzz test and cct.

Pulled codes
P1272
P1274
P1276
P1278

CCT - failed #3 cylinder

Since the buzz test codes were all on the driver side I replaced the ucvh - code p1316 still comes up but still no symptoms.

I've tested resistance at idm 42 pin for all injector wiring and all are within tolerance.

I've also tested the center power pin at the 9 pin connector at the valve covers and got over 1v on both sides.

Any ideas?

Thanks

Did you clear the codes? A lot of codes are stored until reset.

I've cleared them with a simple OBD II reader, not sure if that clears them out of the IDM or not. When i clear them the SES does go off for about 15 miles of driving then comes back.

Then the code is clearing. After the computer checks it again, the code comes back.

Makes sure the harness on both sides is nice and tight. Remove and replace the connectors to makes sure there's good contact.
